I am trying to make two containers responsive without using media queries or JavaScript.
When the screen size is 500px or less, I want the containers to stack on top of each other and take up 100% of the screen width.
But when the screen size exceeds 500px, I need the containers to be displayed side by side, occupying equal widths of the horizontal space.
The challenge is that this needs to work in IE8. Can it be achieved with just CSS?
