jak zrobić podświetlenie aktualnie wybranej pozycji w menu Opcje

[wazi20]

Witam

Zwracam się z prośbą. Czy moglibyście mi pomóc w małej modyfikacji skryptu.
Chciałbym, aby po wybraniu jakiejś pozycji z menu została ona podświetlona na jakiś inny kolor. Bo w tej chwili nie wiadomo co aktualnie zostało wybrane.

Z góry dziękuję.
Pozdrawiam

Niestety takie rozwiązanie nie działa

Kod

.sdmenu {
    width: 257px;
    font-family: Sans-Serif;
    font-size: 12px;
    padding-bottom: 10px;

    color: #FFF;
}

.sdmenu .title, .sdmenu .titlehidden{
    display: block;
    padding: 5px 0;
    font-weight: bold;
    color: black;
    background: #FFF url(title.gif) repeat-x;
    text-align:
}

.sdmenu .title {
    border-bottom: 1px solid #DDD;
}

.sdmenu .arrow {
        margin-left: 10px;
    margin-right: 7px;
}

.sdmenu .titlehidden {
    border-bottom: none;
}

.sdmenu #top {
    background: url(toptitle.gif) no-repeat;
}

.sdmenu .submenu {
    overflow: hidden;
}

.sdmenu .submenu a {
    padding: 5px 0;
    text-indent: 10px;
    background: #FFF;
    display: block;
    border-bottom: 1px solid #DDD;
    color: #066;
    text-decoration: none;
}

.sdmenu .submenu a:hover {
    background : #066 url(linkarrow.gif) no-repeat right center;
    color: #FFF;
}
.sdmenu .submenu a:active {
    background : #000000;

}

Nie wprowadzaj w błąd.

[frok]

<a href="#">Menu1</a>

zmień na:
<a href="#" class="zamiana">Menu1</a>

w stylach dopisz:


a.zamiana, a.zamiana:visited {
text-decoration: none; //usuwa podkreślenie
color: #fff; //kolor czcionki
font-weight:bold; //pogrubienie, jezeli nie potrzebne to usun linijke

}

a.zamiana:hover {
text-decoration: none;
color: #000; //kolor po najechaniu

}
