Textbox on Background Image

Something like this in your head section, setting the position atributes:

<style>
p.pos_fixed
{
position:fixed;
bottom:60px;
right:5px;
}
</style>

And this in the body of your webpage, which uses a paragraph <p> to place whatever content you like, including a textbox in any position that you like, which is set in the <style> settings above.

<p class="pos_fixed" align="right" id="help">Your text or other HTML elements here... It will be placed in whatever position that is set in the style settings in your head section. A textbox here is fine, as is almost any other HTML elements. The resolution of the users browser doesn't matter, as the position is set using number of pixels, so if the resolution is lower, the HTML will be placed in the same place on the graphic background.</p>
