Hi Carel,

Welcome to T3 Framework community.

For your question, to change background color of megamenu dropdown, please open the custom.css file then add the following css rule:

.t3-megamenu .mega.open > .mega-dropdown-menu, .t3-megamenu .mega.dropdown-submenu.open > .mega-dropdown-menu {

background: #000;

}

You can change the color to whatever you want.

Gardner.

Thanks a lot Gardner, that .css is much better than mine !,

However, my question was merely where the custom.css should/can be placed to be picked up by T3.

I "think" you can have only one custom.css, located under \templates\t3_bs3_blank\css\. It will be picked up for all themes. ?
I "think" you can not have a custom.css specific for a theme ? and as such located in templates\t3_bs3_blank\css\themes\red (if you select the red theme) or generally in : templates\t3_bs3_blank\css\themes\<theme name> ?

Not a big deal for me, but I was wondering if I did miss something.

gr, Carel.

Yes, you have it exactly right.

As far as I know, the only customizable files in the <theme name> directories are the LESS files in \templates\t3_bs3_blank\less\themes\<theme name> where several Less files are generated by default.

That's right Michael. If you have any more concern, let me know. I am willing to help you.
