Hello,

I have a webpage where I have four buttons.
when the page is loaded all you can see are the buttons but when you click a button a content appears, content which changes when clicked on another button. This is done by a siompel js script with an onClick command.

What I want to do is to change the background of the active button, I mean if I click on the first button, and see the content related to this button, then the button should have a different background.

All I managed to do so far is to change the background on hovering over the buttons, but it's just not enough for the visitors to know which content they are reading.

Please help!

<title>EXAMPLE PAGE</title>

</head>

<body>
     <div id="detail">
      <form>
       <input type="button" class="tab" value="Content 1"
        onClick="MM_showHideLayers('shtab1','','show','shtab2','','hide','shtab3','','hide','shtab4','','hide')"  />
       <input type="button" class="tab" value="Content 2"
        onClick="MM_showHideLayers('shtab1','','hide','shtab2','','show','shtab3','','hide','shtab4','','hide')"  />
       <input type="button" class="tab" value="Content 3"
        onClick="MM_showHideLayers('shtab1','','hide','shtab2','','hide','shtab3','','show','shtab4','','hide')"  />
       <input type="button" class="tab" value="Content 4"
        onClick="MM_showHideLayers('shtab1','','hide','shtab2','','hide','shtab3','','hide','shtab4','','show')"  />
      </form>
      <div class="tabsdet">
      <!-- HIDDEN INFORMATION TO BE SHOWN ONCLICK -->
      <div id="shtab1">
       <p>This is the content that is associated with button 1</p></div>
      <div id="shtab2">
       <p>This is a different content associated with button 2</p></div>
      <div id="shtab3">
       <p>This is yet another different content associated with button 3</p></div>
      <div id="shtab4">
        <p>This content is related to button4</p></div>
       </div>
      <!-- END - HIDDEN INFORMATION TO BE SHOWN ONCLICK -->
     </div>

</body>
</html>

And this is the CSS:

#detail input {display:inline; background:transparent url(img/title.png) repeat-x;
color:#fff; font-size:14px; font-weight:bold; border:none; height:25px; padding: 0 3px 0 3px;}
#detail input:hover{background:transparent url(img/activetitle.png) repeat-x;}
#shtab1, #shtab2, #shtab3, #shtab4 { position: absolute; top: 100px; left:30px; border:1px solid #99ccff; padding:10px; 
background:transparent url(img/filtr.png) repeat; visibility: hidden;}
#shtab1 p, #shtab2 p, #shtab3 p, #shtab4 p{width:500px;}

Here you have it!
