First of all. This is JAVASCRIPT, this will not work on Wordpress! So, users can input search parameters (EG. Script Codes) then it would redirect the current page to google then search the inputed text.

put this where you put html replace 'background' with the background color of your site, replace 'link' with the link you want it to go to, replace 'cmts' with the color you want the text to be when you mouse over, and replace 'text' with some words ;) example:

Weasel's first javascript! on your website it pops up an alert with a response depending on the time! put it where you'd put html/javascript!
