Offset anchors

Description:

A user from Neve's Facebook group is using a stick to top header. When having a stick to top header, whenever you use an anchor, the anchor will go under the header, and it will not be visible. I was able to provide a solution for our user and here's what I wrote:

Ah, I understand what you mean now. I'm not sure we can provide a solution for the theme. I will open an issue on GitHub to discuss the matter with my colleagues. Until then, here's a custom solution that you can implement by yourself.
So let's say you have a title where the anchor goes to. Whenever you add your anchor, add a class also. Let's say we name our class 'offsetanchor'. You also need to add the following code to Customizer:

.offsetanchor::before{
content: '';
display: block;
height: 230px;
margin-top: -230px;
visibility: hidden;
}

Modify '230px' for height and margin-top with the offset you need. The margin-top is negative. Here's a video of how this would work: https://vertis.d.pr/v/CEPKvt
I hope it helps!

I'm not sure if we can have a better solution inside the theme.

Alternatives:

We can write a documentation about offset anchors.

No file or test is named in the issue. Start by reproducing an anchor jump with a sticky top header and inspect the theme's Customizer-related styling; define whether the result should be a built-in offset or documentation for the existing workaround, then verify that anchored content remains visible.
