What is CSS.

Q15. What is CSS?
Ans.
CSS is a text document (or style-sheet) that is commonly used to define the style and layout of an XML document, such as font size, font color, line width, and background color. The same CSS document can be used in multiple XML documents. The CSS document, which has the .css extension, contains the style code for the structure, such as heading, paragraphs, and links, of the XML document.
