I'm trying to add an :active link class to the following CSS, but I'm lost!

.menu {font-size:0.85em;padding-bottom:1px;}

/* remove all the bullets, borders and padding from the default list styling */
.menu ul {padding:0;margin:0;list-style-type:none; height:2.8em; background:#006436;}

/* style the sub-level lists */
.menu ul ul {width:15em;}

/* float the top list items to make it horizontal and a relative positon so that you can control the dropdown menu positon */
.menu ul li {float:left;height:2.8em;line-height:2.8em;}

/* style the sub level list items */
.menu ul ul li {display:block;width:8em;height:auto; line-height:1em;}

/* style the links for the top level */
.menu a, .menu a:visited {display:block;float:left;height:100%;font-size:1em;text-decoration:none;color:#fff;background:#006436;padding:0 2em 0 1em; border-left:1px solid #006436; border-right:1px solid #006436;}

/* style the sub level links */
.menu ul ul a, .menu ul ul a:visited {display:block;background:#006436; color:#fff;width:12em;height:100%;line-height:1em; padding:0.5em 1em;}
* html .menu ul ul a, * html .menu ul ul a:visited {width:14em; w\idth:12em;}


/* style the table so that it takes no part in the layout - required for IE to work */
.menu table {position:absolute; left:1px; top:0; width:0; height:0; font-size:1em; z-index:-1;}


/* style the level hovers */
/* first */
* html .menu a:hover {color:#fff;background:#87d192; position:relative; z-index:100;}
.menu li:hover {position:relative;}
.menu :hover > a {color:#fff;background:#87d192;}


/* hide the sub levels and give them a positon absolute so that they take up no room */
.menu ul ul {visibility:hidden;position:absolute;height:0;top:2.8em;left:0;width:14em;}

/* position the third level flyout menu */
.menu ul ul ul{left:12em;top:0;width:14em;}


/* make the second level visible when hover on first level list OR link */
.menu ul :hover ul{visibility:visible; height:auto; padding-bottom:3em; background:transparent url(images/trans.gif);}
/* keep the third level hidden when you hover on first level list OR link */
.menu ul :hover ul ul{visibility:hidden;}
/* keep the fourth level hidden when you hover on second level list OR link */
.menu ul :hover ul :hover ul ul{visibility:hidden;}
/* make the third level visible when you hover over second level list OR link */
.menu ul :hover ul :hover ul{visibility:visible;}
/* make the fourth level visible when you hover over third level list OR link */
.menu ul :hover ul :hover ul :hover ul {visibility:visible;}

I would like the :active to have the background colour 87d192

If anyone could point me in the right direction that would be appreciated.

Been looking at it too long now!

Thanks

A:active {background: #87d192; text-decoration: none}
.class A:active {text-decoration: underline overline}

PM me your page if neither works, i'll reconfig your setup.
