Is it possible to have multiple sticky elements stacked on top of each other in pure CSS?
The desired behavior can be seen here: https://webthemez.com/demo/sticky-multi-header-scroll/index.html
Only I'd prefer to use pure CSS, instead of a Javascript implementation. I've experimented a bit with multiple sticky elements, but I can't keep them from pushing out other sticky elements. I've tried placing them in the same stacking context:
#sticky .sticky-1,
#sticky .sticky-2
{
position: sticky;
}
#sticky .sticky-1
{
top: 1em;
z-index: 1;
}
#sticky .sticky-2
{
top: 2em;
z-index: 1;
}
But can't get it to work, as you can see in below . Any insights would be greatly appreciated!
#container
{
display: grid;
grid-template-columns: 50% 50%;
}
#sticky .sticky-1,
#sticky .sticky-2
{
position: sticky;
}
#sticky .sticky-1
{
top: 1em;
z-index: 1;
}
#sticky .sticky-2
{
top: 2em;
z-index: 1;
}
#fixed
{
position: relative;
}
#fixed .sticky-1
{
position: fixed;
top: 0;
}
#fixed .sticky-2
{
position: fixed;
top: 1em;

</div>You need to make all the elements to stick to the same container (containing block) by adding some offsets.
Here is a basic example where the elements will stick to the body:
body {
margin:0;
min-height:200vh;
border:2px solid;
}
.first {
height:50px;
background:red;
position:sticky;
top:0;
}
.second {
height:50px;
background:blue;
position:sticky;
top:52px;
}
.third {
height:50px;
background:green;
position:sticky;
top:104px;
}<div class="first"></div>

</div>A stickily positioned element is an element whose computed position value is sticky. It's treated as relatively positioned until its containing block crosses a specified threshold (such as setting top to value other than auto) within its flow root (or the container it scrolls within), at which point it is treated as "stuck" until meeting the opposite edge of its containing block ref
The most important part here is the last one. So if all the elements aren't in the same container each one will reach the edge of its container and the sticky behavior will stop there. Note how, in the last example, each element will stop moving when reaching the bottom-border of its containing block
