Custom styling TB-Megamenu I'm attempting to custom style the TB-Megamenu because there are a lot of color changes I would like to make. I would also like to change how when the mouse leaves an item it stays that color for a moment before changing back to it's default state. I understand that I can always change the css in a custom stylesheet that's also included like

#main-menu-wrapper .tb-megamenu .mega-nav &gt; .active a, #main-menu-wrapper .tb-megamenu .dropdown-menu .mega-nav &gt; .active a {
    background-color: #000;
    color: #fff;
}


But hunting down everything I need to change is quite the task. Especially when trying to hunt down what selections I need to make for things elements are active, or elements that the mouse just left. The fact that the TB-Megamenu is changing the classes also makes it difficult. At the same time the TB-Megamenu is being used elsewhere, and I'd like to keep the default style for them, without affecting other sites that are on the same instance of drupal. 
Is there a better way to accomplish this? Or do I need to continue trying to search and override each element?
TB Mega Menu module has a CSS folder. Use that as your reference. It also has a styles sub-folder that IMO would be of greatest benefit. Just copy one of the whole styles/*.css files over and adapt it. No need to hunt it down.

To target a menu on a specific page you will need to inject a CSS class into that page via a preprocess_page hook or Context or some other preferred method. You need to set it closer to root level (ie html or body tag) than that of .tb-megamenu class occurence in the html. Having done that all you need do is prepend your injected class to every single selector that you use, as in:

.tb-megamenu.style-black .nav &gt; li &gt; a:focus,
.tb-megamenu.style-black .nav &gt; li &gt; a:hover {
  background-color: #222;
  color: #7bb9e0;
}


becomes:

.my-page-class .tb-megamenu.style-black .nav &gt; li &gt; a:focus,
.my-page-class .tb-megamenu.style-black .nav &gt; li &gt; a:hover {
  background-color: #222;
  color: #7bb9e0;
}
