Adjusting the sidebar and content width

Hello, is it possible to have a css code that sets the left and right sidebar 160px wide and the middle content part 728px wide?
Normally I use a layout without sidebar. But I wonder how it will stand like this. Normally, it is necessary to make the site width 771px for 728px. How should the site width be in such a layout: (160 + 728 + 160)

And of course I will use the following code that you mentioned earlier in order to make sidebars not visible on mobile:

@media all and (max-width: 799px) {

  .sidebar {
    display: none;
  }
}

Yours truly.
