Add hover to links in signature

Question

I am making signatures for my company and I would like to add a hover change color to some of the links. I know there must be a way to do it but all the information must be contained in the one file and I can't get it to work. Everything works fine, except I can't figure out how to make the text change color when I hover.

This is for the Mail app on Mac OSX.

Here's my current code:

<table width='320' id="sig" cellspacing='0' cellpadding='0' border-spacing='0' style="width: 320px; margin: 0px; padding:0px;">
<tr>


<!-- The formatting of the image -->
<td width="86" style="width: 86px ;margin-left: 20px; padding: 0px;">
<a href='http://blog.jimdo.com/wp-content/uploads/2014/01/tree-247122.jpg' style="border:none;text-decoration:none;">
<img moz-do-not-send= "true" src= "http://blog.jimdo.com/wp-content/uploads/2014/01/tree-247122.jpg" alt="DatIMG" style=" border:none; width:100px;"></a>
</td>

 <!-- Formats the text to be beside, not below, the image-->     
<td width="10" style="width: 10px; min-width: 10px; max-width: 10px; margin: 0px ; padding: 0px;">&nbsp;</td>
<td valign='top' style="margin: 0px ; padding: 0px;">
<table id="sig2" cellspacing='0' cellpadding='0' border-spacing='0' style="padding: 0px; margin-top: 10px; font-family: 'Helvetica'; font-size: 14px; color: #58585a; border-collapse: collapse;-webkit-text-size-adjust: none;">

Answer 1

You can't do that by just using HTML the most simple way of change the text when hovering is giving each signature you want a to change colour a class and then using CSS Hover function to change the colour.

Example below

HTML CODE:

<div class="signature1">
<a href="link.html"> YOUR LINK </a>
</div>

CSS CODE:

.signature1{
color: #fff
}

.signature1 hover{
color: FF0000
}

That is the way i'd do it as its easier and if you wanted to change it the future it just as easy.
