javascript - Background-Only Opacity -


i have trouble css.

i have code (example):

<div class="background" style="background: url(sample.jpg) no-repeat;">     <div class="text-title">title</div>     <div class="text">random stuff</div> </div>

what want is, when hovering on background image - should opacity lets 0.3, how make it, inside items stay same opacity 1?

here's best trick in book. https://jsfiddle.net/xbxvr8as/

if have trouble css might bend brain jsfiddle pared down can it. play removing single styles see happens.

the crux relative:position element. can add "pretend" div-like thing using :after pseudo-element. give pseudo-element bunch of properties - important being position:absolute allows sit straight underneath text.

html

<div id="a">     stuff in here ..... </div>

css

#a{position:relative} #a:after{     content:" ";     position:absolute;     display:block;     top:0;left:0;right:0;bottom:0;     background-color:#f00;     z-index:-1;     opacity:0.2; }
