what version of Atahualpa and WP?
What is your URL?
You need to look at the source of the page and then determine what the CSS Selector and CSS Rule you need. for example a CSS Selector might be 'div.searchbox' while a couple CSS rules might be something like 'position:relative; top:-50px;' and put together it would be
HTML Code:
div.searchbox {
position:relative;
top:-50px;
}
Now this is strictly an example, yours maybe different which is why w3schools.com is such a good resource for learning both CSS and HTML
If you want customize your site even more than the theme options allow, you need to learn some CSS and HTML.
BTW - none of the links in STB signature are sites of their's, they are just links to others peoples helpful sites
