css - Bootstrap's "dropdown open" background color -

-

i'm trying change background color of li element when it's class changes "dropdown" "dropdown open" on click. i've managed change color of text (which a). can't change parent li properties.

i've copied code here: http://www.bootply.com/fk88owgjgl. @ end of css file you'll see i've managed code concerning background color of li , of it's child. can't understand why font color works , background doesn't.

any appreciated.

thanks time

i think problem related floating elements inside form, adding clear fix help.

.navbar-right .dropdown-menu form:after {     content: "";     display: table;     clear: both; }

and there bit background @ bottom due parent margin, can rest.

.navbar-right {     margin-bottom: 0; }

use below, if need change background of search item itself(with magnifying glass) when active.

li.dropdown.open > a:focus {   color: #000;   background: red; }

demo: http://jsfiddle.net/1ub60vcj/3/

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
