This website is all about CSS, a key tool in web design. In case you’re not familiar with CSS: CSS is the sister technology to HTML that is used to style your web pages. The details are in the tutorial, but for now we can say that CSS can make your web pages look great!
CSS (Cascading Style Sheets) is used to style and layout web pages — for example, to alter the font, colour, size and spacing of your content, split it into multiple columns, or add animations and other decorative features. This module gets you started on the path to CSS mastery with the basics of how it works, including selectors and properties, writing CSS rules, applying CSS to HTML, how to specify length, colour, and other units in CSS, cascade and inheritance, and debugging CSS.
