I have problem with z-index value in child element. Structure looks like this:
#header { position: relative; z-index: 2; width: 100%; height: 15vh; display: block; margin: 0 auto; background-color: white; color: #44a9ff; padding: 0; overflow: hidden; border-bottom: 3px solid #44a9ff; -webkit-box-shadow: 8px 1px 41px 0px rgba(0, 0, 0, 0.75); -moz-box-shadow: 8px 1px 41px 0px rgba(0, 0, 0, 0.75); box-shadow: 8px 1px 41px 0px rgba(0, 0, 0, 0.75); } #main { position: relative; z-index: 1; width: 100%; height: 75vh; display: block; margin: 0 auto; overflow: hidden; padding: 0; background: url('img/main_bg.jpg') no-repeat center center; background-size: cover; border-bottom: 3px solid #44a9ff; } #box { position: relative; z-index: 10; width: 40%; height: 38vh; background-color: #44a9ff; float: right; color: white; display: block; overflow: hidden; }
<div id="nav"> <ul> <li><a href="#">..</a></li> <li><a href="#">..</a></li> </ul> </div> <div id="main"> <div id="box"> </div> </div>
Element #nav
has z-index 2, because there is box shadow in the bottom. #main
has z-index 1, because when is higher, shadow is not visible. And than there is #box
, which has z index 3, because I need it to cover shadow from #nav
. But it probably has value of z-index from #main
, so it doesn't cover it. How could I fix this please?
try moving #box
out of #main
and give it a custom css code to get it to the right position
<div id="nav">
<ul>
<li><a href="#">..</a></li>
<li><a href="#">..</a></li>
</ul>
</div>
<div id="box">
</div>
<div id="main">
</div>
Try taking #box
out of #main
and setting it absolute
above with right
& top
coordinates:
#header { position: relative; z-index: 2; width: 100%; height: 15vh; display: block; margin: 0 auto; background-color: white; color: #44a9ff; padding: 0; overflow: hidden; border-bottom: 3px solid #44a9ff; -webkit-box-shadow: 8px 1px 41px 0px rgba(0, 0, 0, 0.75); -moz-box-shadow: 8px 1px 41px 0px rgba(0, 0, 0, 0.75); box-shadow: 8px 1px 41px 0px rgba(0, 0, 0, 0.75); } #main { position: relative; z-index: 1; width: 100%; height: 75vh; display: block; margin: 0 auto; overflow: hidden; padding: 0; background: url('img/main_bg.jpg') no-repeat center center; background-size: cover; border-bottom: 3px solid #44a9ff; background: green; } #box { /* set it absolute */ position: absolute; /* tweak coordinates to your benefit */ right: 8px; top: 19vh; z-index: 3; width: 40%; height: 38vh; background-color: #44a9ff; color: white; display: block; overflow: hidden; }
<div id="header"> <div id="nav"> <ul> <li><a href="#">..</a> </li> <li><a href="#">..</a> </li> </ul> </div> </div> <div id="main"></div> <div id="box"></div>
