Create A Custom Search Box Using Css/html

I have an affiliate search box I need to build using CSS/HTML.

You will need to design a web form with the needed fields that will produce a URL that will go to the 3rd party site and pull up a customised search – I will supply all needed parameters, fields and the search URL.

The web form will need to be a certain size and colour – again, I will let you know the details when the project is accepted.
