HTML - Alternate To Getelementbyid

Basically I'm not wanting to change my established code too much just yet and I want to know if there's some script way to detect someone's browser and then use a different .css file for each type of browser I want to set it up for. I know pretty much how to detect the browser type but not so much how to do the <link href= part so that it would work in the script. Anyone have a suggestion?...

PS- I know I can just made an index.html that links over to a different page for each and every browser but that is really not an option with the amount of time it takes to update the page every day.

I had the following code,how can I make alternate color for each row?Actually I retrieved the data from database and bind to table,so I do not know the total number of row.How to make alternate color??


Code:

   Private Sub TableDetails(ByVal MydinProdNbr As String, ByVal OldStockCode As String, ByVal SupplierPrdNbr As String, ByVal Description As String, ByVal Packing As String, ByVal ListPrice As String, ByVal Disc1 As String, ByVal Disc2 As String, ByVal Disc3 As String, ByVal TotalOrderQty As String, ByVal DeliveredQty As String, ByVal SelectedQty As String, ByVal FOCQty As String, ByVal DiscountAmt As String, ByVal NetUnitPrice As String, ByVal Amount As String)
         
                    lbl.Text = lbl.Text & "<tr bgcolor=#99CCFF>"
                    lbl.Text = lbl.Text & "<td style=""font-size: 7pt"" width=""63pt"">"
                    lbl.Text = lbl.Text & MydinProdNbr
                    lbl.Text = lbl.Text & "</td>"
                    lbl.Text = lbl.Text & "<td style=""font-size: 7pt"" width=""60pt"">"

What I'm trying to do is get the googlemaps iframe to change if i hit to corresponding 3 links at the bottom.

So I tried to use getElementById(leftcolumn).innerhtml = "blah blah" to change the entire content of the div but it isnt working. Please advise.

Or would there be a simpler solution like creating 3 hidden divs and just do display:block; to display them? Am I making sense?

<script type="text/javascript">
function changeSrc()
{
document.getElementById("myImage").src="help_button.gif";
}
</script>
</head>
<body>
<img id="myImage" src="audio_button.gif" width="107" height="98" />
<br /><br />
<input type="button" onclick="changeSrc()" value="Change image" />

This is my html code, while go through the output, get only one rectangle and button, i can't see this image,??????...
which i include in the code.i already put the image in same folder.
