CSS stands for Cascading Style Sheets. CSS describes how HTML elements are to be displayed on screen, paper, or in other media. CSS saves a lot of work. It can control the layout of multiple web pages all at once. External stylesheets are stored in CSS files
CSS is used to define styles for your web pages, including the design, layout and variations in display for different devices and screen sizes.
The style definitions are normally saved in external .css files. With an external stylesheet file, you can change the look of an entire website by changing just one file!
CSS Example
body { background-color: lightblue; } h1 { color: white; text-align: center; } p { font-family: verdana; font-size: 20px; }
