What is CSS?

Cascading Style Sheets (CSS) is used to format the layout of a webpage.

With CSS, you can control the color, font, the size of text, the spacing between elements, how elements are positioned and laid out, what background images or background colors are to be used, different displays for different devices and screen sizes, and much more!

Tip: The word cascading means that a style applied to a parent element will also apply to all children elements within the parent. So, if you set the color of the body text to "blue", all headings, paragraphs, and other text elements within the body will also get the same color (unless you specify something else)!

Using CSS

CSS can be added to HTML documents in 3 ways:

• Inline - by using the style attribute inside HTML elements

  External CSS

  An external style sheet is used to define the style for many HTML pages.

  To use an external style sheet, add a link to it in the section of each HTML page:

  Example

  
  
  
   
  
  

  This is a heading

  
  

  This is a paragraph.

  The external style sheet can be written in any text editor. The file must not contain any HTML code, and must be saved with a .css extension.

  Here is what the "styles.css" file looks like:

  "styles.css":

  body {
    background-color: powderblue;
  }
  h2 {
    color: blue;
  }
  p {
    color: red;
  }

  Tip: With an external style sheet, you can change the look of an entire web site, by changing one file!
