What is CSS? – Definition

CSS (Cascading Style Sheets) is a style sheet language that describes the style of the HTML document.  It describes how HTML elements are displayed on a page. CSS saves a lot of work as it may control the layout of multiple pages at once. Style formatting is usually saved in a separate .css file. Thanks to this, you can modify the layout of the whole site by changing only one file.
