Because the max-width of my page is 952px. I want the content to be hidden the instant the user begins to collapse the page size.
But I want the content to be visible again at 800px, but then to be hidden again at 799px from there on in (would be up to 0px).
The reason for this is because there is a moment at 800px when the sidebar becomes hidden, and so there would be sufficient space to display my content. But while the sidebar is visible, this would not be possible.
