Fixed position but relative to container

Closed 4 years ago.
I need this button fixed at the bottom of the parent div and floating over its scrolling content.
I'm really surprised this doesn't work. I expected position: relative on the parent in combination with bottom: 0 on the fixed element to achieve this..
PS: the button must be inside the div.
div {
position: relative;
width: 200px;
height: 100px;
overflow-y: scroll;
background-color: lightblue;
}
button {
position: fixed;
bottom: 0;
}
body {
height: 200px;
}
<div>

You code is almost working.You need to do only one change.
Add position: sticky; for div element.
