How to stretch the VK group widget over the entire height of the block?

Question

css

Hello everyone! Faced such a situation. You need to stretch the VK group widget over the entire height of the parent block. And the parent block is equal to the height of the window. How to do it?

I do it and it doesn't work. In widget options, 100% height doesn't roll.

#vk_groups {width:100%!important;height:100%!important}

Answer 1

Well, if it is equal to the height of the window, put 100vh

Answer 2

Through the developer tools in the browser, look at the inner blocks of the widget, set their height and immediately stretch and narrow the browser. That's how you find a solution.
