Learning HTML5 and CSS3

If you learned how to build websites in the late 1990s or early 2000s and want to get back into the world of coding, you may be wondering how to code in HTML5 and CSS3. Fortunately, these latest versions of the web's most basic building block languages aren't that much different from their predecessors. Still, if it really has been a long time since you've built a website from scratch, or if you're learning for the first time, a refresher education or introduction is a great idea.

What Are HTML5 and CSS3?

To use the metaphor of a car in describing the internet, one might say that HTML is the basic frame and body of the car, while CSS is the finish. You need the frame and body (HTML) in place to add on important comfort and structural elements (CSS), like seats and body paint. If you apply CSS to a webpage without HTML, you aren't going to see anything rendered on your screen. If you code a webpage with HTML but leave out the CSS, your page might look like it came from a 20th-century time machine.

If you're already familiar with code, you likely know this. But updates to these essential coding languages mean you can build a better website than ever with HTML5 and make it even more beautifully designed and organized with CSS3. HTML5 was approved by the World Wide Web Consortium in 2014, while CSS3 has been approved in bits and pieces starting in 2011. These are incremental updates of the same coding languages you learned before.

How Are They Different?

The exact ""how"" of the difference between current and past versions of these coding languages can get a bit complex based on what you already know and also because the sheer volume of differences can take a while to parse out. Suffice it to say that the changes reflect the changing ways we use the web. HTML5 makes a lot more allowances for audio and video content, for example, while CSS3 introduces a more sophisticated and varied range of style options.

If you're thinking about getting back into coding websites either for fun or to make a career change, you might want to take a refresher course to not only brush up your old skills but also to add on to what you already know. Learning HTML5 and CSS3 can help you design sites that feel fresh and modern. A Udacity Nanodegree program like Intro to Programming may be just what you need to get back in the swing of things and integrate HTML5 and CSS3 into your coding repertoire.
