Want to learn more about widget? Click here.

Better:

Learn more about widgets

A compromise solution:

Click here to learn about widgets

Achieved using this bit of CSS:

body {color:#000;}
a{color:#006;font-weight:bold;}
a:hover,a:focus{color:#090;}
a.clickhere, a.clickhere:hover, a.clickhere:focus {text-decoration:none;color:#000;font-weight:normal;/* to match body color and weight */}
a.clickhere span {text-decoration:underline;font-weight:bold;color:#006;}
a.clickhere:hover span, a.clickhere:focus span {color:#090;;text-decoration:underline;font-weight:bold}
