Ajax Search Dropdown Menu 2

Hi,

1. Some time ago I had an issue with the Ajax Search on a site. The problem is back. All search results are black and unreadable (see screenshot) Here is the previous topic:
https://kriesi.at/support/topic/ajax-search-dropdown-menu/#post-588790

As discussed, I added the following to CSS, but If I delete all of it nothing changes. If I add it back nothing changes. I am not putting it in Quick CSS, I’m adding it to the Child theme CSS and clearing my cache to check results.

/*Ajax Search*/

.header_color .ajax_search_title {
	color: white;
}

#top .header_color .ajax_search_entry:hover .ajax_search_title {
	color: black;
}

.header_color .ajax_search_excerpt {
	color: #999999;
}

2. Also, there is this just below it. Can you remind me what this is used for?

#top #header .av-main-nav > li > a:hover > .avia-menu-text,#top #header .av-main-nav > li > a > .avia-menu-text {
	color: white !important;
}

3. Is there a simpler way to do #1 above? Perhaps in Advanced Styling? CSS just seems to break over time.

Thank you,

Jas
