scrollIntoView Scrolls just too far

Question

Smooth scroll to the proper position

Get correct y coordinate and use window.scrollTo({top: y, behavior: 'smooth'})

const id = 'profilePhoto';
const yOffset = -10; 
const element = document.getElementById(id);
const y = element.getBoundingClientRect().top + window.pageYOffset + yOffset;

window.scrollTo({top: y, behavior: 'smooth'});

Position Anchor By Absolute Method

Another way to do this is to position your anchors exactly where you want on the page rather than relying on scrolling by offset. I find it allows better control for each element (eg. if you want a different offset for certain elements), and may also be more resistant to browser API changes/differences.

<div id="title-element" style="position: relative;">
  <div id="anchor-name" style="position: absolute; top: -100px; left: 0"></div>
</div>

Now the offset is specified as -100px relative to the element. Create a function to create this anchor for code reuse, or if you are using a modern JS framework such as React do this by creating a component that renders your anchor, and pass in the anchor name and alignment for each element, which may or may not be the same.

Then just use :

const element = document.getElementById('anchor-name')
element.scrollIntoView({ behavior: 'smooth', block: 'start' });

For smooth scrolling with an offset of 100px.

You can do it in two steps :

el.scrollIntoView(true);
window.scrollBy(0, -10); // Adjust scrolling with a negative value here

If it's about 10px, then I guess you could simply manually adjust the containing div's scroll offset like that:

el.scrollIntoView(true);
document.getElementById("containingDiv").scrollTop -= 10;
