How to change an element on the VK page and its design using the Tampermonkey script?

Question

css

Good day, I'm wondering if it's possible to change an element on the vk.com website page using scripts in Tampermonkey?
For example, change the width of the frame of the rectangle with the text "side" and its position on the page and background color.

Answer 1

For example like this (and by analogy change the desired properties)
Or with jQuery
$("#myprofile_wrap>a>span").css({"color":"red"});
