The dynamically generated page looks like this, and the menu style is as follows:
ul#topnav .sub ul li a
{

float: none;
text-indent: 0; /*- -Reset text indent--*/
height: auto;
background: url(../../Images/menulist/navlist_arrow.png) no-repeat 5px 12px;
padding: 7px 5px 7px 15px;
display: block;
text-decoration:none;
color: #fff;
}
My font is transparent, and the background iframe is also transparent, so it is affected by the underlying Elemental influence. Now I want to change the font color so that it is not affected by the underlying element, but changing the color has no effect. I tested it myself and it was because of the influence of the underlying iframe. Please tell me how to change the font color without changing the iframe?
