.wrap {
max-height: 200px;
overflow-y: auto;
position: relative;
border: 2px solid green;
}
.content {
height: 1000px;
}
.absolute {
position: absolute;
bottom: 0;
left: 0;
width: 100%;
background-color: red;
}<div class="wrap">
<div class="content"></div>
<div class="absolute">absolute</div>
</div>As you can see in snippet. When I scroll the .wrap, the .absolute also go away too. Why this happen. And how can I keep the .absolute on the bottom.
>Solution :
With position: sticky;, like so:
.wrap {
max-height: 200px;
overflow-y: auto;
position: relative;
border: 2px solid green;
}
.content {
height: 1000px;
}
.absolute {
position: sticky;
bottom: 0;
left: 0;
width: 100%;
background-color: red;
}<div class="wrap">
<div class="content"></div>
<div class="absolute">absolute</div>
