I know it's easy to change the color if you use the standard format and css :
<i class="icon-cog"></i>
But I'm forced to use the html format () of the icon:
<input id="btn-save-workout" type="submit" class="btn btn-default pull-right btn-sm" value=" Save">

Not sure it's possible with this syntax. I tried putting a div around with a color without success. Thanks in advance,
