Sorry, but it is not possible to define several elements. Is it possible to see the problem? Currently auto scroll is working fine for the test on laptop.

It does work fine for laptops, PCs and mobile phones, because I managed to pick a good offset in px.

But it's a bad offset for tablets. Here is a screenshot of 768x1024px screen width offset - ibb.co/hM5fsDM . I added an arrow, where a question title is located, right after I press one of answers. I used this website for testing - responsivetesttool.com/ . It's a good website for such purposes.

I just don't want to make a bigger offset to fit all the screen widths at once. Because if I will fit tablets, then mobile phones and laptops/PCs will have very big offset. I don't want that. Tablets are less important to me, but still ARE important.

That's why I am asking you for a 4th time, if there is any css selector for this offset, so I can use @media for it?

It is not possible to use @media queries for this purpose. The plugin accepts absolute values as offset or an element (usually it is sticky header) to get height of this element at runtime. In your case probably it needs to specify another element (not #masthead) because site theme for some dimensions adds margin to this element and it can affect on offset. We guess It is possible to use an inner element in #masthead element.
