WordPress Mobile Web Development: Beginner's Guide

Chapter 2. Using Responsive Themes

So, we’ve had a look at some plugins that can quickly and easily make your site mobile-friendly. These are a really easy way to make your site work great on mobile devices, but if you’re anything like me, you’ll have noticed a couple of downsides. The first downside is that with a plugin, you get a mobile site that looks just like a lot of other mobile sites out there with very little opportunity to add your own design. And the other one is that it’s difficult to display all of the content from your site, especially if you’re using widgets and a custom header.

So, you want to overcome these limitations, but you’ve still got limited time and next to no budget to make your site mobile. What can you do? The answer may just be to use a pre-existing mobile or responsive theme.

To get to grips with responsive themes, in this chapter we’ll:

  • Learn about mobile and responsive themes, and the difference between them

  • Learn how responsive themes work and what they offer...

Mobile themes versus responsive themes


In the past, most site owners who wanted a mobile-friendly site would use a separate mobile theme for the site with a design specifically for mobile devices. Some would also use different mobile domains. In fact, this is what those plugins we learned about in the last chapter are doing.

If you’re using a mobile theme, you tell WordPress to switch themes if the visitor is using a mobile, and stick to the desktop theme if he/she’s using a—yes you’ve guessed it—desktop PC.

A responsive theme, on the other hand, uses the same theme and similar styling for both sites, but uses a combination of a fluid layout and media queries to make the layout and content different on different-sized devices. It doesn’t just work for mobiles; responsive themes can change the look of a site on tablets or on really large screens, too.

Note

Responsive design—key terminology

To get to grips with a responsive design, you’ll need to understand the following:

  • Fluid layout: This is a...

Identifying the best approach for your site


Before starting, it’s a good idea to think about your website, its content and functionality, and consider what the best approach might be.

First let’s look at the options available to us.

Options for developing a mobile site

There are five main options for developing a mobile site as follows:

  • Using a mobile plugin: This gives us a mobile-friendly site with the minimum of effort, but doesn’t give us much scope to incorporate our own design into the mobile site, as we saw in the previous chapter. Many mobile plugins also don’t target tablet devices.

  • Using an off-the-shelf responsive theme: There are a number of free responsive themes available in the WordPress plugin repository. In this chapter we’ll look at some of them and see how we can tweak them so that our mobile site is more consistent with our desktop site.

  • Using an off-the-shelf responsive theme for mobile devices and our existing desktop theme for desktop computers: We achieve this by using...

Twenty Eleven—configuring the default WordPress theme


Since Version 3.2, every installation of WordPress comes with the Twenty Eleven theme (http://wordpress.org/extend/themes/twentyeleven) already installed and ready to go with. And the great news is that it’s responsive. So let’s see how it looks when applied to the Carborelli’s site.

Time for action—configuring the Twenty Eleven theme


To configure the Twenty Eleven theme, perform the following steps:

  1. 1. Activate the theme. At the moment, we have a bespoke theme activated, so we need to activate the Twenty Eleven theme. Let’s do that by clicking on Themes in the Appearance menu, as shown in the following screenshot:

    So how does the Carborelli’s home page look now? First, we will see how it looks on a desktop, as shown in the following screenshot:

    Next, we will see it on mobile devices with screens narrower than 480px, as shown in the following screenshot:

    Hmm. It’s not quite right, but it doesn’t look bad. Can you spot the main changes Twenty Eleven has made to the site, compared to the original theme? They are as follows:

    • The widgets are missing. The map has disappeared because it was in a widget. There is a search box but it’s in the header.

    • A comments box has been added. We don’t want one of those on our home page.

    • A wide image has been added at the top, which isn’t relevant...

More responsive themes—installation and configuration


But of course, we’re not limited to Twenty Eleven if we want an off-the-shelf responsive theme. A search for the terms—mobile and responsive, in the WordPress theme repository at http://wordpress.org/extend/themes/ reveals 14 themes in total, so let’s have a look at some of them.

Scherzo—installation and configuration

Scherzo (http://wordpress.org/extend/themes/scherzo) was one of the first free responsive WordPress themes, released at the beginning of 2011. It includes options for the background and header, which give it some flexibility, but in my view its main selling point is the fact that it’s very clean and minimal, which would make it a great parent theme to add our own styling to using a child theme.

Time for action—installing and configuring the Scherzo theme


Let’s see what we can do with Scherzo. To install and configure the Scherzo theme, perform the following steps:

  1. 1. Start by downloading Scherzo and activating it on the Manage Themes options page. Out of the box, this is how the Carborelli’s site now looks on desktop computers:

    And here’s how it looks on mobile devices:

    The desktop version has quite a lot of white space, and the mobile version has a problem with text wrapping around the images. The issue with the wrapping around the images would have to be solved within a media query, which is outside the scope of this chapter. The white space can be easily fixed by changing the theme options.

  2. 2. The Header screen lets us upload a header image and change the color of the header font, so let’s do that first.

  3. 3. The Background screen gives us the option to change the page background, which results in less white space.

What just happened?

We installed Scherzo and made some changes to the...

Time for action—installing and configuring the Ari theme


Let’s try it out on the Carborelli’s site. To install and configure the Ari theme, perform the following steps:

  1. 1. Download Ari from http://wordpress.org/extend/themes/ari and activate it on the Manage Themes options page. Let’s have a look at what it does to our site without any tweaks, on each of the desktop, iPad, and mobile. The following screenshot shows the Ari theme on the desktop:

    The following screenshot shows how it looks on the iPad:

    Finally, our site with the Ari theme on a mobile looks like the following screenshot:

    As with Scherzo, there are some issues with wrapped text in the mobile version, but the changing column layouts are a nice touch across the different devices.

  2. 2. The next step is to make some design and branding alterations, which we can do via the Theme Options screen. Change the color of the header text, the page background, and the body text if you want. You can also upload an image to use as the logo—this...

Time for action—installing and configuring the Codium Extend theme


To install and configure the Codium Extend theme, perform the following steps:

  1. 1. Download Codium Extend from http://wordpress.org/extend/themes/codium-extend and activate it on the Manage Themes options page. So, how does it look out of the box on the Carborelli’s site? Let’s look at each of the desktop, iPad, and mobile renderings of the site. The following screenshot shows how Codium Extend looks on the desktop:

    The following screenshot shows how Codium Extend looks on the iPad:

    Finally, the following screenshot shows our site with the Codium Extend theme on a mobile:

    Hmm. The widgets seem to have gone a little awry. On the desktop, we have some extra widgets, and in the tablet and mobile version there are no widgets at all. The menu is in the wrong order, and finally the colors are nice enough but not consistent with our brand. Let’s fix each of these problems.

  2. 2. On the Widgets screen, there are two available widget areas...

Taking it further—using a responsive theme just for mobile devices


It may have occurred to you while working through this chapter that some of these themes give the Carborelli’s site a look and functionality that is great on mobiles. But, it’s a shame to lose the desktop theme with all its detail and elements such as the call to action button and contact details in the header.

It will probably also have occurred to you that some of these themes gave us a really quick and easy way to create a responsive site without writing any code.

So, what if we could have our cake (or our ice cream) and eat it? Is there a way to display the existing theme for desktop visitors, but display a responsive theme for mobile and possibly tablet visitors?

The great answer is yes, there is, and it involves the use of theme switchers.

Note

Do you remember what a switcher is, which we saw in Chapter 1, Using Plugins to Make Your Site Mobile-friendly? It’s a plugin that switches the site’s theme when someone visits it...

Time for action—configuring the WordPress Mobile Pack plugin as a theme switcher


To configure the WordPress Mobile Pack plugin as a theme switcher, perform the following steps:

  1. 1. Download WordPress Mobile Pack from http://wordpress.org/extend/plugins/wordpress-mobile-pack/ if you haven’t already, and activate it.

  2. 2. On the Mobile Switcher screen, select the responsive theme from the Mobile theme drop-down list. Here, we will select Ari, as shown in the following screenshot. Click on Save Changes.

  3. 3. Now, let’s see how the site looks, firstly on a desktop and then on a mobile. Note that the site will look the same on tablets as it does on the desktop, as the theme switcher is only activated for mobile devices. The following screenshot shows how the site looks on the desktop:

    The look of the site on the mobile is shown in the following screenshot:

What just happened?

Using a theme switcher plugin (WordPress Mobile Pack), we configured our site so that people visiting it on desktop PCs will see...

Summary


In this chapter we’ve started to work with the responsive design, by choosing and configuring a few responsive themes and testing them on our site.

We learned the difference between mobile and responsive themes, and the options available to us while choosing how to develop our mobile site. We also learned what to consider when choosing our approach and our theme, how to install and configure some free responsive themes, and how to combine an off-the-shelf responsive theme with a theme switcher to retain our existing desktop theme but improve the user experience on mobile devices.

But, this is just scratching the surface of what we can do with responsive themes. By building responsiveness into our own theme, we can retain all of the branding, design, and content we want for the Carborelli’s site, while ensuring that the site looks great on desktops, mobiles, and tablets. We can take it further by ensuring that mobile users don’t have to download large image files, and harness APIs and...

We live at a time when it's essential to make our websites or web apps accessible from several different types of devices: desktop computers with big screens, smartphones with small touchscreens, tablets, netbooks, televisions, consoles, etc.As a result, starting in the web development world is becoming more difficult for newbies. This book tries to make that path easier by doing a thorough explanation of all steps to be followed to make our websites or web apps more accessible.Going further into details on the book's contents, it has to be stressed that is focused to newbies, but to make the most of it is highly recommended to have experience with CSS. PHP isn't essential, although it helps. Nor is it necessary experience with WordPress, but if you've used before you will feel more comfortable following explanations.This book is part of the series "Learn by doing" by Packt Publishing, which means that it's eminently practical. It's advisable to read it in front of your computer and write, modify and experiment with the code you will find that is abundant.It consists of 10 chapters that I will comment below:Chapter 1: Starting with the basics, this chapter tries to make a website accessible using free WordPress plugins. We use an example website called Carbonelli's, which is an ice cream store, and we'll see continuously throughout the book. Rachel McCollin makes an exhaustive review of the five most used WordPress plugins to make a responsive site, explaining their pros and cons and installing and configuring two of them.Chapter 2: Using plugins is a valid option in some cases, but it has many limitations. If you need something more flexible, the next step is to use a responsive WordPress theme, which is the focus of this chapter. Again we find an exhaustive comparison of different responsive themes. Rachel walks you through the installation process and shows the result for desktop computers and mobile devices.Also install a theme switcher plugin type. These kind of plugins change the WordPress theme when they detect that the user is accessing from a mobile device.Chapter 3: So far, we have seen the possibilities we have to develop our responsive website without touching code, but this will change in this chapter that focuses on Media Queries. We start making our layout to fluid, changing the pixel dimensions to percentages, then we'll define breakpoints for desktop computers, tablets in portrait mode, smartphones in landscape mode and smartphones in portrait mode. Finally we'll create Media Queries for each of these breakpoints.Chapter 4: This chapter continues where we left off in the previous one and we'll play much CSS code. Basically we will make the necessary adjustments in Media Queries that we created for the Carbonelli's website to looks properly at any resolution. The process followed by Rachel is: shows a site's image before the changes, explains the necessary adjustments and the reason, shows the code to achieve our goal (change the font size, adjust width, margins, etc.) and finally shows a picture with the result. An extensive and very detailed chapter.Chapter 5: Now that we have a website with a responsive design for any type of device, it's time to improve the user experience (UX). To achieve this, certain adjustments are necessary in the theme, such as changing the font size, using ems instead of pixels, changing font type and modifying the navigation. All this according to the device's resolution.Chapter 6: One of the big issues to ensure a responsive design is to deal properly with images and video. The reason is that, unlike the rest of elements that make up a website, in this case isn't enough to fit the width with the layout, the real challenge is to ensure that the mobile devices doesn't download the images full size version while we only need to show a much smaller one. We all know that data consumption has a price in such devices when we are not using WiFi, so it's a very important issue for our users.Well, this chapter exactly focuses this and solve the problem using a plugin that allows you to serve different content based on the device.Chapter 7: Following improvements in user experience, now that we are able to detect the type of device accessing our site, we can provide data tailored for different devices. I have found it very interesting to know the kind of information searched by the users depending on the type of device that they are using.Chapter 8: This chapter explains, among other things, what's a web app and what options we have when converting a website into a web application. Then we will see step by step what we need to do in order to begin transforming the visual appearance of Carbonelli's website in a web application.Chapter 9: Once we have the web app visuals, we must change out app's functionality. Rachel starts by reviewing the different types of plugins that we can use: E-commerce plugins, geolocation, social media, etc. to finally explain how we can add a feature that allows our users to create and sell custom ice creams using PayPal as a payment method.Chapter 10: The last step before launching our web app is to test it in a variety of browsers and devices. This chapter shows us the different options we have to achieve it: using browsers' plugins that modify the browser size or change the User Agent, and use various mobile devices' emulators.In summary and as I said at the beginning of this review, it's a practical book that forces us to adopt an active attitude when it comes to reading. Isn't enough to sit back into your favorite couch, you have to roll up your sleeves and start writing code and experimenting. In addition, each chapter includes a brief test that will help us to check if we master the skills. At the end of the book we can find the solutions and explanations to each question.This is a book that, as the title suggests, is focused to newbies. Surely not make you an expert on the subject, but it's a great start to keep you learning about responsive design, something that are more and more important every day.Finally I must emphasize that, although the book focuses on modifying a website using WordPress, you will find content very useful even if you don't use this CMS, especially from chapter 3, which is when we started to modify CSS code.

Give your WordPress sites a boost!So many of us web developers and designers depend on WordPress to fulfil the needs of our customers, and it is often hard to find information on niche WP topics, especially things like making WP sites responsive. I know there are responsive themes available for WP, but that is only a small part of creating mobile-friendly sites.So I opened Rachel's book with anticipation, having read some of her work before on various web sites, and I wasn't disappointed. She covers pretty much anything you could possibly need to get started in this area in a friendly approachable style, starting from the basics and moving up to more complicated topics. She starts off by giving sound advice on using mobile plugins and themes - great, because there is such a lot to choose from out there. The next major section of the book looks at using media queries to optimise different facets of your layout, from general containers, to nav menus, to text.Then we get to the real meat of the responsive umbrella - responsive images. Rachel presents some pretty nifty techniques for making video and images responsive on a WP site, including serving different file size images, rather than just changing the display size.The rest of the book concludes nicely, with tips for creative web app interfaces for WP sites, dynamically altering the content sent to (or displayed on) different devices using server- and client-side technologies, and how to handle testing and updates. If you're a WP developer working in this day and age, you'll probably find a lot of useful stuff crammed inside these pages.

Book is split into 10 chapters. First chapter deals with use of plugins to deliver mobile version of a website. Step by step instructions are included for few popular plugins. Second chapter is about using responsive themes that use same theme for mobile and desktop viewing, adjusting layout to different screen size using CSS.Chapters 3, 4, 5 and 6 are dedicated to building a responsive theme from setting up media queries for different devices, setting the layout to follow the responsive approach, working with theme elements and optimizing content for smaller screens (images before all). Chapter 8 deals with the detection of the device visiting the page and different method for this.Chapters 9 and 10 are dedicated to web apps, and methods for building them, and what plugins and tools you can use to enhance the app. Last chapter is about testing the mobile websites without using devices, all through desktop simulators for different platforms.Chapters on web apps are lacking and they are missing the much needed information about different mobile platforms and specific aspects needed for such apps on different devices. There is only a list of websites for different mobile systems and nothing more. testing chapter is also lacking information for more popular mobile environments, most likely due to the fact that only Opera has real testing tools for its mobile browsers.This is very good book. It was written for beginners, and it delivers relevant information for various methods on making mobile friendly website. Step by step tutorials in it are great, easy to follow and understand. There are some things that maybe are not exactly for beginners, but even code and CSS examples are followed by a lot of explanations.

This book comprehensively covers the options available to make a Wordpress site work well on all mobile devices - phones and tablets. Whilst aimed at the beginner, more advanced developers will find many useful tips and resources throughout the book. WordPress Mobile Web Development: Beginner's Guide starts with some simple steps a developer can take to enhance how his site will look on different devices. The meat of the book discusses what is meant by responsive design and how to provide a good user experience on all devices using more hands-on techniques. Native apps are discussed and what the developer can do to make use of a browser's in-built functionality. There is also a discussion on useful techniques and strategies for testing and debugging your site.Each chapter provides numerous resources for downloading and references for further research. Techniques are detailed via a step by step approach and accompanied by a good use of screenshots. Many of the chapters include pop quizzes for you to test your understanding and retention.The first two chapters address the resources available to make a wordpress site mobile friendly. There are a number of themes and plugins available to download, enabling the developer to quickly ensure their site works well on all devices. The book explains the different impact these resources have on both development and end result. The author walks the reader through the steps to implement responsive themes or plugins including a description of the options and how to use them.The next five chapters focus on the theory of responsive design and more advanced techniques to customise the mobile experience. Issues of accessibility, response times and ease of interaction are addressed both from a theoretical and practical perspective. The author repeatedly refers back to these issues to help the developer determine which technique is the most suitable to use.Specific chapters focus on the different aspects of a website - page layout, text, navigation, images and videos - and how to make them responsive. In these chapters, you will learn how to use media queries, optimize images as well as file size and adjust your layout depending on device size and orientation. The author identifies different strategies to employ depending on the objective of the page and offers solutions for different problems. For example if space is an issue for displaying the navigation, she suggests using an accordion effect or using a fixed position button to link to the navigation further down the page. You can download a sample chapter at [...]The 2 chapters on native apps provide a good overview on their pros and cons versus mobile sites. Immediate and longer term solutions for a developer to consider are identified and as in previous chapters, third party solutions are offered for further investigation. The final chapter on testing is excellent, providing invaluable techniques and resources for testing. Clearly testing on all mobile devices is challenging and this chapter provides a number of options.I highly recommend this book to beginning developers with a small caveat - experience with Wordpress is essential and knowledge of CSS is useful. More advanced developers and developers who do not use Wordpress will also benefit from the many resources and references discussed. My only criticism of this book is that, unlike some books, it does not provide the full code for the example site which would enable the user to properly try out all the code and techniques.
