How to rotate background in CSS?

问题:

I want to achieve a skewed/rotated background div with solid color.

Just like this:

I know there is a trick with rotating your background to create chamfered corners but will it work out here? Or jQuery will do better?

Second problem I might have with this is a content layer (marked as red) overlaying the two background divs.

Can you help me please?

Thanks in advance, and sorry for any language mistakes.

You can do this with pseudo elements.

I changed the colours to make visible

<div class="foo"></div>

.foo {
    position: relative;
    width: 200px;
    height: 100px;
    background: blue;
}

.foo:after {
    content: '';
    display:block;
    height:100px;
    width: 100px;
   -webkit-transform: skew(30deg, 0deg);
    background: red;
    left: 150px;
    position:absolute;
    z-index: -1;
}
