What Is CSS?

CSS is a style sheet that describes the presentation of an HTML based page. It's one of the cornerstones of the web. CSS stands for cascading style sheets and separates presentation and content to improve accessibility and reduce time spent coding. It enables you to build multiple pages that share the same formatting but specify the CSS to each particular page. Separating presentation and content allows you to render multiple versions of a single page for alternate formats such as mobile, on-screen, or by voice. It's maintained by W3C, which provides a free validation service. CSS is supported by other markup languages in addition to HTML such as XHTML and SVG. It also integrates with things like javascript.

Why Learn CSS

Web browsers apply CSS rules to web pages to affect how they're displayed. Learning CSS allows you to create beautiful web pages that work across a variety of formats. It integrates with other programming frameworks to build out things like background color, text color, font size, and a variety of other HTML elements. CSS changes HTML to a Document Object Model (DOM). The browser combines the content with the style information to create a single object within the web browser's memory. Learning CSS allows you to maintain your build through external stylesheets, internal stylesheets, or inline styles.

CSS Certifications and Courses

CSS tutorials can give you a basic understanding, but making a living building web projects may require more than just a passing knowledge. Harvard University's certification gives you a grand overview of basic development tools. Web developers gain knowledge of various frameworks as they pertain to CSS and HTML. For a targeted certification, you can learn from the originals, W3C, with a CSS basics course designed to familiarize you with CSS properties, the CSS grid, and style attributes, as well as best practices in web design. Other courses can also round out not only your knowledge of CSS but how it fits into the larger scheme of web development.

CSS and Your Career

CSS is one of the cornerstones of the web and learning it gives you huge potential to build multilevel platforms for your organization or to work as an independent developer. CSS gives your projects consistency and allows you to cut down on time you spend building through a well-maintained set of stylesheets and by allowing you to reuse elements from things you've already built. CSS could be the beginning of your career in development.
