change the background color of a link using css

Hi, I have a page with an iframe and links. When I click on the link the background of that link change, but when I click anywhere in the document the background changes back.
How can I keep the :active background until another link is clicked no matter what happens in the iframe or elsewhere in the document?

my links look like this:
<span><a class="index_vertical_links" href="javascript:jumpto('<?php echo "$main_output"; ?>')" >Page</a></span>
<span><a class="index_vertical_links" href="javascript:jumpto('<?php echo "$display_form"; ?>')" >some other page</a></span>
<span><a class="index_vertical_links" href="javascript:jumpto('<?php echo "$add_new?cat_add=1"; ?>')" >other page</a></span>

my css looks like this:
a.index_vertical_links:link,a.index_vertical_links:Visited
{
width:235px;
height:20px;
padding-left:20px;
float:left;
color:#ffffff;
background-color:#3f5d83;
border-right:1px solid #264266;
border-top:1px solid #3f5d83;
border-bottom:1px solid #3f5d83;
text-align:left;
text-decoration:none;
letter-spacing:1pt;
word-spacing:0pt;
font-weight:normal;
font-size:12px;
font-family:MS Sans Serif,Arial,sans-serif;
line-height:18px;
}

a.index_vertical_links:Hover
{
width:234px;
height:20px;
border-left:1px solid #264266;
float:left;
color:#e4ab13;
background-color:#787b6a;
border-right:1px solid #787b6a;
border-top:1px solid #264266;
border-bottom:1px solid #264266;

letter-spacing:1pt;
word-spacing:0pt;
font-weight:normal;
font-size:12px;
font-family:MS Sans Serif,Arial,sans-serif;
line-height:18px;
}

a.index_vertical_links:active,a.index_vertical_links:focus
{
width:235px;
height:20px;
padding-left:20px;
float:left;
color:#e4ab13;
background-color:#787b6a;
border-right:1px solid #787b6a;
border-top:1px solid #264266;
border-bottom:1px solid #264266;

letter-spacing:1pt;
