Browser compatibility

The term browser compatibility refers to the ability of a given Web site to appear fully functional on the browsers available in the market.

The most powerful aspect of the Web is what makes it so challenging to build for: its universality. When you create a Web site, you’re writing code that needs to be understood by many different browsers on different devices and operating systems!

To make the Web evolve in a sane and sustainable way for both users and developers, browser vendors work together to standardize new features, whether it’s a new HTML element, CSS property, or JavaScript API. But different vendors have different priorities, resources, and release cycles — so it’s very unlikely that a new feature will land on all the major browsers at once. As a Web developer, this is something you must consider if you’re relying on a feature to build your site.

In this course, we are providing references to the browser support of HTML5 features using these two resources: Can I Use and Mozilla Developer Network (MDN) Web Docs.

Can I use

Can I Use provides up-to-date tables for support of front-end Web technologies on desktop and mobile Web browsers. Below is a snapshot of what information is given by CanIUse when searching for "CSS3 colors".
