  • How do you keep parents of floated elements from collapsing? [duplicate] 16 answers

    • This should work: <div style="background-color: #302683; overflow: hidden;">

    See the example: http://jsfiddle.net/b8q836zs/1/

    Overflow: hidden|auto will make an element establish a 'new block formatting context' — an isolated container, which will keep it from flowing into the space occupied by preceiding floats — see: CSS 2.1 - floats.
