I needed to reproduce the image in css, I already tested some transform options and I can not stretch one end.
My question is how to get the bottom of the left and make it bigger down the right.
I did this in css with after and before it does not look good I just wanted to have a square and stretch one end, it should have some way by css

div:before { content: ''; border-right: 318px solid transparent; border-top: 100px solid blue; position: absolute; bottom: -99px; left: -1px; }
div:after { content: ''; border-right: 318px solid transparent; border-top: 100px solid white; position: absolute; bottom: -98px; }
