Before You Begin

Each great journey begins with a humble step. Our upcoming adventure in the land of HTML and CSS is no exception. Before we can do awesome things with data, we need to be prepared with a productive environment. In this section, we shall see how to do that.

Installing Chrome

In this book, we have used Chrome version 76, which was the latest version at the time of publication. Make sure you have downloaded and installed the latest version of Chrome to ensure an optimal experience.

To install Chrome on Windows, follow the instructions given here: https://www.google.com/chrome/

For other platforms such as macOS and Linux, scroll down to the bottom left-hand corner of this website: https://www.google.com/chrome/ and click on Other Platforms, and choose accordingly.

Installing Visual Studio Code

Here are the steps to install Visual Studio Code (VSCode):

1. Download the latest VSCode from https://packt.live/2BIlniA:

Installing the web sever

Some exercises in the book will require the use of a personal web server to run the scripts and view the pages you'll be creating. If you do not have a personal web server already set up, you can use the following steps to get one installed.

To begin, you will need to go to https://www.apachefriends.org/index.html and download the XAMPP package for your operating system. XAMPP is available for Windows, Mac, and Linux.

Instructions for Windows

1. Once the web server package has been downloaded and installed on your system, open the XAMPP Control Panel and check the status of your web server. If Apache is highlighted in green, then the web server is running:
   

   Figure 0.4: The XAMPP Control Panel

   If it is not highlighted in green, then you will need to start the Apache web server:

   

   Figure 0.5: Starting the Apache Web Server for Windows

2. Click the first Start button in the control panel that corresponds to Apache. The web server will then initialize and start so you can use it.
3. To check if your web server is running correctly, open your browser, type localhost into the browser's URL bar and then hit Enter:
   

   Figure 0.6: Navigating to localhost in the browser

   If your installation was successful and Apache is running, you will get the XAMPP welcome page:

   

   Figure 0.7: Viewing the XAMPP Welcome Page

4. Next, open your XAMPP directory so you understand where to place your files when you want to use the web server to view your pages. From the XAMPP Control Panel, click the Explorer tab:
   

   Figure 0.8: Navigating to the File Explorer

5. This will open the Windows Explorer and show the files used by XAMPP for running your web server. Locate the folder named htdocs. This is the folder that holds any files that you want to view in the browser:
   

   Figure 0.9: Viewing the Web Server Folders and Files

6. Any files you place into this folder can be accessed through your localhost. For example, we see the file applications.html. If we want to access this file in the browser, we would type localhost/applications.html:
   

   Figure 0.10: Navigating to the applications.html Page

7. Press Enter and your browser will open the file. You can now place any folders or files you wish to open using the web server, by placing them into this directory.

Instructions for Mac

1. Download MAC file from this link: https://www.apachefriends.org/index.html.
2. Double click the downloaded .dmg file (for example: xampp-osx-7.4.5-0-vm.dmg)
3. Drag the DMG image into application as seen below:
   

   Figure 0.11: XAMPP Installation screen

4. To start XAMPP, go to Finder -> Applications -> XAMPP OR press CMD + Space (Spotlight search) and type "XAMPP". You will see the following result:

12. Now go to your web-browser and type-in localhost:8080 (as visible in the above figure) and you will see the same "Welcome" screen.
13. To place your files into XAMPP, click on the "Volumes" tab and click on the "Mount" button. Once clicked, the other two options "Unmount" & "Explore" will be activated for you. Now click on "Explore" button to go to the LAMPP folder:

14. When you click on "Explore" button, you see Finder window will open and search for "htdocs" folder as shown below:
    

    Figure 0.20: Finder with htdocs view

    There you can see applications.html file.

15. Navigate that file from the web-browser and save all your files in this folder to access them on your server:
