How to make an expanding link block with hover offset?

Question

css

Actually for your project, you need to make a menu like on this site techmarkets.ru, only not only in the header, but below .... before pointing clip2net.com/s/3DHEx5A after pointing clip2net.com/s/3DHEMpP to the link area. You need to do the same but only on html and css.
I will be grateful for help
