I was looking around but I couldn't find anything on backgrounds.

Anyway how do you change the color of the background with this code:

<form ACTION=URI>
<select name=lissamenu3
onchange="location.href=(form.lissamenu3.options[form.lissamenu3.selectedIndex].value)">
<option value="0"> Choose One</option>
<option value="0"></option> (This line adds a space in your menu)
<option value="http://www.lissaexplains.com"> Home</option>
<option value="http://www.lissaexplains.com/basics.shtml"> Basics</option>
<option value="http://www.lissaexplains.com/tools.shtml"> Links</option>
</select>
</form>

<form ACTION=URI>
<select name=lissamenu3
onchange="location.href=(form.lissamenu3.options[form.lissamenu3.selectedIndex].value)">
<option value="0" style="background-color: #000000;"> Choose One</option>
<option value="0"></option>
<option value="http://www.lissaexplains.com"> Home</option>
<option value="http://www.lissaexplains.com/basics.shtml"> Basics</option>
<option value="http://www.lissaexplains.com/tools.shtml"> Links</option>
</select>
</form>

and so on (the bold part). On lissa's site it says the following:

You just add the following code, but add your own links. Use CSS (input, text area) to change the font and color properties.

so for more codes you can look here:
