Thank You very much for your time and code. This is perfect. Have a nice day!
Thank you very much @hube2, the solution seems pretty easy, but I have a problem: in this way each div “item” has the name of each category and I predict every category name in my CSS.
How instead I could transform your $ cat_class into a generic variable in the sense: I take the name of the current category (the one I’m seeing) and I associate it with a generic class (example: current-class) so in my CSS I could say: if the class is current-class then this is the rule.
My CSS Code:
.category-carousel .cat-icon{
border:2px solid #0057ff;
display:inline-block;
height:50px;
width:50px;
line-height:46px;
border-radius:100%;
-webkit-border-radius:100%;
-moz-border-radius:100%;
-webkit-box-shadow: 1px 1px 10px -6px rgba(0,0,0,0.3);
-moz-box-shadow: 1px 1px 10px -6px rgba(0,0,0,0.3);
box-shadow: 1px 1px 10px -6px rgba(0,0,0,0.3);}
/*Current Category*/
.category-carousel .cat-icon.category-fotografia{
border:2px solid #000;}
Thanks a lot for the answer.
