How to make background color full width?

Question

css

It turns out that the navigation came out like this

But specify height 790px; is also not good, because if the screen is smaller, then it will turn out that the footer will go to the next block. And if you make it

position: fixed;
height: 100%

Try using vh size for your block:
height: 100vh;
