Suppose I have a div:

div {
    height: 100px; 
    width: 500px; 
    background: blue; 
    margin: 0 auto; 
} 

And I want it to bee two mode - skew to each side -

Here is the base form - /

How could I get the above two forms?

Update :

If it required using JavaScript - do it.

• javascript
• html
• css
• skew

• You can't make two divs out of one without using JavaScript or some other dynamic language. You need to pick one or the other, or add another div. – TylerH Commented Aug 19, 2014 at 15:57
• It's not clear what you are trying to do. – Paulie_D Commented Aug 19, 2014 at 15:58
• @Paulie_D : what is not clear ? just get the div as the two attached forms ... – URL87 Commented Aug 19, 2014 at 16:00
• 1 This is a hammer to crack a nut! However you might want to do it like so: stackoverflow./questions/22069704/skew-one-corner-of-image. But I'd stick with triangles: stackoverflow./questions/16748387/… – Hashem Qolami Commented Aug 19, 2014 at 16:03
• @TylerH not pletely true. You can create new block elements by using :before and :after pseudo-classes – o--oOoOoO--o Commented Aug 19, 2014 at 16:03
