Single 1 pixel diagonal line background


i try to add a diagonal line in the background of a div. i wonder if it's possible to do it without to use a .png image. I saw some css options but the render quality is poor and the line don't touch both side.

If you can live without it being exactly 1px, you can use pure CSS on a single div by using a background gradient:

enter image description here

div {
   width: 400px;
   height: 400px;
   background: linear-gradient(135deg, #ff3232 0%,#ff3030 49.6%,#d6d6d6 50%,#ff3030 50.4%,#ff0000 100%);

The catch is that you set gradients by % so you likely will never get exactly a 1px line in the center. But it's lean markup.
