How to make such a feature?

Question

Layout

Hello. How can it be done and in general, what is this called? https://kentatoshikura.com/
When you hover over a link, it magnetizes to the cursor and stretches up to a certain point, and then returns to its place? I'm looking for a simpler option (crutches).
And the second question: how can you organize such a hover as on the See more link?

Answer 1

It's called css and javascript.
Through devtools, you can see exactly how it was done there, I don’t see the point in copying the code here.
