Mastering Bootstrap 4

Chapter 2. Making a Style Statement

In the previous chapter, we showed you a first glimpse of MyPhoto, the Bootstrap website that we are going to build up throughout the following chapters. Now it is time to get our hands dirty, and actually start building the first section of this website. A first pass at an element of the Services section that presents the list of print sizes available to order. We will achieve this by building a grid using Bootstrap's grid system, creating image elements within the grid system, applying image modifiers, and leveraging Bootstrap's utility classes to create visual indicators and optimized layouts specific to different display resolutions.

By the end of this chapter, through code examples and studying the Bootstrap source code, you will have gained a deep understanding of the following:

  • Bootstrap's grid system
  • Responsive images within Bootstrap
  • Bootstrap's helper classes
  • Bootstrap's responsive utilities

The grid system

Bootstrap's grid system is arguably its most impressive and most commonly used feature. Therefore, mastering it is essential for any Bootstrap developer as the grid system removes many of the pain-points associated with page layouts, especially responsive page layouts. The grid system solves issues such as the horizontal and vertical positioning of a page's contents and the structure of the page across multiple display widths.

As already noted in Chapter 1, Revving up Bootstrap, Bootstrap 4 is mobile-first. As such, it should come as no surprise that the grid system is optimized for smaller viewports and scales up to suit larger viewports, as opposed to scaling down to smaller viewports.

Note

What is a viewport?

A viewport is the available display size to render the contents of a page. For example, the size of your browser window, minus the toolbars, scrollbars, and so on, on your display is your viewport. As already noted in Chapter 1 , Revving Up Bootstrap...

Image elements

As a next step, let us add an image to each column in our grid. Each image will act as a category heading, as well as allow us to display our photographic wares. The images used in the following part, and throughout the rest of the book, are provided with this book. Take a look at the following code:

    <div class="col-xs-6 col-sm-3 push-sm-3">
        <img src="images/small.jpg">
        <h5>Small</h5>
        <div class="row">
            <div class="col-sm-4">6x5</div>
            <div class="col-sm-4">8x10</div>
            <div class="col-sm-4">11x17</div>
        </div>
    </div>
    <div class="col-xs-6 col-sm-3 push-sm...

Responsive utilities

Responsive utilities are a group of media query-based classes that control when an element should be hidden or shown depending on the viewport. One popular use case for this is controlling display specific navigations. For example, a page may have a navigation bar on large displays and have a hidden navigation on small displays which is only displayed when a user chooses to open the navigation.

Let's look at a quick example with our Print Size page. Add the hidden-xs-down class to the img elements:

    <div class="container">
        <h1>Our Print Sizes</h1>
        <div class="row">
            <div class="col-xs-6 col-sm-3 push-sm-3">
                <img src="images/small.jpg" class="img-fluid img-circle
               ...

Helper classes

Bootstrap also provides some utility classes, which Bootstrap refers to as helper classes. The helper classes provide some basic styles to accentuate information on a page. Their purpose is to give the user some context to the information they are receiving and to provide the developer with styling techniques, outside of the grid system.

Context

Bootstrap defines six context types to give a visual indicator to the user of what type of information is being conveyed: muted, primary, success, info, warning, and danger, as well as providing the developer with simple classes to assign context to elements via text color, text-<context> or background color, bg-<context>.

Let's apply some context to our example. We will add two prices to each size: a regular price and a special offer price. We will apply a success context to the special offer price and a muted context to the regular price. Print sizes with prices reduced by €10 or more will be given an info context...

This book gets into the nitty-gritty of Bootstrap 4, and for that it is very helpful. However, the examples in the book leave something to be desired. They provide you with example code, but only snippets; you have to figure out where the sample code should go in your file which is really annoying. Also, many of the examples simply do not work. Even if I copy/paste from the code provided (after modifying it to include the CSS and JS files that their examples left out), it still does not display properly. In the authors' defense, this could be because the book is using Bootstrap-4.0.0-alpha.4 whereas I am using the updated Bootstrap-4.0.0-alpha.5.I also do not like their use of bower. If you use it as they instruct, you'll end up with different versions of jQuery and related plugins than the authors. For example, simply running "bower install jquery" gave them jQuery 2.1.4, but gives me 3.1.1. That may or may not be a problem for these examples, but it is worth noting. Why not just point us to the jQuery download site and let us install it ourselves? Or just use the CDN as they mentioned, then glossed over, early on? That would also fix the problem with their example files not including the JS and CSS files.All that being said, the authors know their stuff. If you're already familiar with Bootstrap 3, this book will be helpful for you. If you're looking to learn how to use Bootstrap, I'd recommend a different book.
