html - z-index of child element of a flex item -


i want absolute positioned child element (.tag-preview-container) of flex item (.image-container) overlap other elements in dom (for instance header .header). i'm setting z-index of absolute positioned element 2 (even 1 should work). however, element doesn't overlap dom element outside flex container(.tags-panel). in fact, cut off container. not setting z-index of other element in dom, root should stacking context. 

<div class="panel-container">   <div class="header">    </div>   <div class="tags-panel">     <div class="image-container">       <div class="tag-preview-container">       </div>     </div>     <div class="image-container">      </div>     <div class="image-container">      </div>     <div class="image-container">      </div>   </div> </div>

this scss code , here's jsfiddle

.panel-container {     width: 400px;   height: 400px;   position: relative;   margin: auto;   .header {     width: 100%;     height: 40px;     background-color: green;   }   .tags-panel {     position: absolute;     background-color: red;     top: 40px;     bottom: 0px;     width: 100%;     overflow-y: auto;     display: flex;     flex-flow: row wrap;     align-content: flex-start;   } }  .image-container {   flex: 0 0 33%;   box-sizing: border-box;   border: 1px solid black;   margin-top: 5px;   margin-left: 1px;   height: 80px;   background-color: yellow;   position: relative;   .tag-preview-container {     background-color: black;     position: absolute;     top: 50%;     left: 50%;     transform: translate(-50%,-50%);     width: 200px;     height: 200px;     z-index: 2;     opacity: 0.5;   } }

the z-index affected overflow property in .tags-panel, removing overflow-y: auto; solve issue. here updated fiddle https://jsfiddle.net/yc5xanax/

overflow-y: auto; automatically wrap/hide content outside .tags-panel container.
