Yes you can. With the latest version of Ulti Counter, the leading part, the actual counter and the tailing part are in a different div. You can give each part seperate a different look in the css file of your template.
The html code will look like this:
<div id="ulti_counter" class="ulti_counter">
<div class="ulti_counter_leading">
your leading text
</div>
<div class="ulti_counter_middle">
actual counter
</div>
<div class="ulti_counter_tailing">
tailing part
</div>
</div>
So if you want e.g. to have the 3 parts in a different color, put the following code in the css of your template:
div.ulti_counter_leading {
color: #ff0000;
}
div.ulti_counter_middle {
color: #00ff00;
}
div.ulti_counter_tailing {
color: #0000ff;
}
