I would like the hyperlinks in an article to stand out more. Is there a CSS file that I can modify the link color and text-decoration?

Thank you in advance for your help.

If you want to customize a template ( logo.gif, color, font or background) and don´t know the css class, please use Firefox with the Firebug extension. Now you can analyze every CSS style for customizing the template CSS.

For example:
If you want to style the basic link you have to add this code to the file: css/custom.css

a {color:#FF0000}
