html - hover is not working on child element -



html - hover is not working on child element -

i have div within div below

<div id="locations"> <div id="h-dragbar"></div> </div>

and css below

#locations { height: 50px; width: 100%; position: relative; z-index: -1; } #h-dragbar{ background-color:black; width:100%; height: 3px; position: absolute; cursor: row-resize; bottom: 0; z-index: 999; } #h-dragbar:hover{ background-color:blue; }

but hover on div id h-dragbar not working. can test code here demo.

what doing wrong? in advance.

in new illustration jsfiddle you've provided, you're setting z-index of -1 parent div i.e. #locations why you're unable perform hover function on kid div i.e. #h-dragbar. need remove negative z-index on #locations , it'll work fine.

update:

i've checked latest fiddle , instead of using negative z-index #locations in order give priority #v-dragbar, can accomplish same using high z-index #v-dragbar, e.g. z-index: 9999, , relatively smaller z-index #locations, e.g. z-index: 9998. it'll work way. here's demo:

class="snippet-code-css lang-css prettyprint-override">body { width: 100%; height: 500px; } #wrapper { width: 100%; height: 100%; } #explorer { width: 13%; min-height: 100%; height: 100%; position: relative; float: left; } #v-dragbar { background-color: black; height: 100%; float: right; width: 2px; cursor: col-resize; z-index: 9999; position: relative; } #h-dragbar { background-color: black; width: 100%; height: 2px; cursor: row-resize; position: absolute; bottom: 0; z-index: 999; } #h-dragbar:hover { background-color: blue; } #v-dragbar:hover { background-color: blue; } #locations { height: 50%; width: 100%; position: relative; z-index: 9998; /*imp*/ } class="snippet-code-html lang-html prettyprint-override"><div id="wrapper"> <div id="explorer"> <div id="v-dragbar"></div> <span style="clear: both;"></span> <div id="locations"> <div id="h-dragbar"></div> </div> <div id="datapoints"> </div> </div> <div id="explorer"> </div> </div>
