Overview of this book

With knowledge of CSS and HTML, you can build visually appealing, interactive websites without relying on website-building tools that come with lots of pre-packaged restrictions. The HTML and CSS Workshop takes you on a journey to learning how to create beautiful websites using your own content, understanding how they work, and how to manage them long-term. The book begins by introducing you to HTML5 and CSS3, and takes you through the process of website development with easy-to-follow steps. Exploring how the browser renders websites from code to display, you'll advance to adding a cinematic experience to your website by incorporating video and audio elements into your code. You'll also use JavaScript to add interactivity to your site, integrate HTML forms for capturing user data, incorporate animations to create slick transitions, and build stunning themes using advanced CSS. You'll also get to grips with mobile-first development using responsive design and media queries, to ensure your sites perform well on any device. Throughout the book, you'll work on engaging projects, including a video store home page that you will iteratively add functionality to as you learn new skills. By the end of this Workshop, you'll have gained the confidence to creatively tackle your own ambitious web development projects.

If you open the Exercise 13.05.html page in a browser that doesn't support either the CSS Paint API or CSS Properties and Values API, you will experience none of the stylings we expect and also some JavaScript errors.

The following screenshot shows the result of running Exercise 13.05.html in the Chrome browser, which does not support the CSS Properties and Values API. The dev tools console panel is open and shows a JavaScript error caused by a lack of support for CSS.registerProperty. The button is difficult to use as it appears with none of the expected styles:

In this exercise, we will make our code more robust and provide a decent experience for those browsers that...
