Dear Chris,
Thanks a lot for using the Portfolio Manager.
You can add the required tab classes and rules to the Mosaic VIew CSS itself.
e.g., if you are using Mosaic Style 1, then add the tabs classes in mosaic_style1.css
located in:
httpdocs/components/com_behance/helpers/html/css/mosaic_style1.css
The class ".bop-option-set" is wrapping the whole tabs area. So in case you wish to add border-radius, use this rule:
.bop-option-set li span{
border-radius: 5px;
}
Note:
Just in case, use !important wherever necessary to override the inline style of the tabs generated.
Hope this helps
Please feel free to let me know if you have any other queries.
