CSS – Cascading Style Sheets
CSS defines HOW HTML elements are to be displayed.
CSS describes the visual style (appearance, layout, color, fonts) of HTML elements.
CSS was designed to separate document layout from document content (which greatly improved HTML flexibility and reduced HTML complexity).
CSS is easy to learn. You can use HTML element names as selectors, and list the style properties inside curly brackets:
font-family:”Times New Roman”;

CSS saves a lot of work!
The CSS definitions are normally stored in external files. This enables a web developer to change the appearance and layout of every page in a web site, just by editing one single file!
If you have ever tried to change the style of all elements in all your HTML pages, you understand how you can save a lot of work by storing the style definitions in an external file.
