Box model
120 x 70 content box with padding and a double border.

Floating box

This box should sit to the left of this paragraph on wider screens.
The paragraph should flow beside the floating box and continue naturally. On browsers without full CSS support, the box may simply appear above the paragraph, which is an acceptable fallback.
