The following HTML markup won't work on a production site.
<div class="iconleft 109">TEXT</div>
This is the code in the custom.css file.
.iconleft.\31 09,
.iconleft.\31 12,
.iconleft.\31 10,
.iconleft.\31 11,
.iconleft.\31 20 {
background: #B0CD00;
}
.iconleft.\31 09
works on localhost with xampp and no aggregation. On the production site, where Advanced CSS/JS Aggregation is activated, it wont work for 109.
In the aggregated CSS file, I see .iconleft.\31 9
as CSS class. It seems that 0 has been removed.
Do you have any hint?
.iconleft.\00003109
instead of.iconleft.\31 09
