Have you tried using the !important flag on the style? !important allows you to decide which style will win out. Also note !important will override inline styles as well.
#example p {
color: blue !important;
}
...
#example p {
color: red;
}
Another couple suggestions:
Add a span inside of the current. The inner most will win out. Although this could get pretty ugly.
<span class="style21">
<span style="position:absolute;top:432px;left:422px; color:Red" >relating to</span>
</span>
jQuery is also an option. The jQuery library will inject the style attribute in the targeted element.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js" type="text/javascript" ></script>
<script type="text/javascript">
$(document).ready(function() {
$("span").css("color", "#ff0000");
});
</script>
Hope this helps. CSS can be pretty frustrating at times.
