Download and saveĀ reset.css stylesheet into your assets folder. Then link it as external CSS so the code will look like this inside your <head> element of your html page:
<link rel="stylesheet" type="text/css" href="assets/reset.css" />
You may copy the code above and paste it after the <title> tag or use the CSS Styles panel inside Dreamweaver to link the reset.css file.
Instructor Note:
The point of using this particular stylesheet is to strip your page of any default style that may cause browser inconsistency. Eric Meyer, the guru of CSS, talks more about this in his article CSS Tools: Reset CSS.
If you already have an external CSS file, you can use the import command to import the reset.css into your main stylesheet. It works like combining multiple stylesheet. Add this code to your main stylesheet to import:
@import url(reset.css");
