Understanding the rules of inheritance in CSS3 helps you create interesting sites that require a minimum of maintenance. By following these rules, when maintenance is required, you normally have to make just one change, rather than changing hundreds of items individually. It pays to experiment, though, so you can understand the full effects of inheritance and the effects of using multiple styles together.

  1. Create a new HTML5 file with your text editor.

    Your editor may not support HTML5 files. Any text file will do.

  2. Type the following code for the HTML page.

    <!DOCTYPE html>
    <html>
    <head>
     <title>Inheritance Example</title>

     </div>
    </body>
    </html>
