CSS (Cascading Style Sheets) allows you to apply styles to web pages. More importantly, CSS enables you to do this independently of the HTML that makes up each web page.
CSS has become a crucial part of building websites and blogs. CSS goes hand in hand with HTML to display your website the way it's intended to be displayed. Here, you'll find CSS tutorials, code examples, and CSS reference material.
