Fixed Position

Copy linkTweet thisAlerts:
Apr 02.2021

I have a container DIV on my webpage, inside that another content DIV with loads of text information.

My first DIV is position relative. Second was absolute and a help icon DIV was fixed on the top right corner.

However I want the help icon to slide down the page, so I moved it to position fixed.

However it now gets placed top right of the page not the parent container and moves down the page. Is this normal?

@SempervivumApr 02.2021 — This can be achieved by a few lines of javascript:
``<i>
</i> window.addEventListener('scroll', event =&gt; {
const rect = document.getElementById('container').getBoundingClientRect();
// if the help icon has disappeard to the top:
// shift it down:
if (rect.top &lt; 0) {
document.getElementById('help-icon').style.transform = 'translateY(' + (-rect.top) + 'px)';
} else {
document.getElementById('help-icon').style.transform = 'translateY(0px)';
}
});<i>

</i>`</CODE>
'container' ist the ID of the second container 'help-icon' is the ID of the help icon.

This can be done by CSS and <C>position: sticky;</C> either:
<CODE>`<i>
</i> #help-icon {
float: right;
position: sticky;
top: 0;
}<i>
</i>``
but as I'm more of a javascript guy I implemented the other solution first.
