How to remove space on right side?

Question

I have the problem with white space on right side. Looks like its problem with width, i tried to fix the issue with max-width on html and body but nothing happens.

Problem: http://prntscr.com/j0c1y5

P.S. This is not the full code space appears on every part of the page.

Answer 1

use this code.

*, *::before, *::after {
    box-sizing: border-box;
}

you are getting scroll because with width: 100%; & padding. padding value get outside space so width: 100% + padding = 100%+ you can see the link for more information. https://www.w3schools.com/cssref/css3_pr_box-sizing.asp
