I have a triangle (JSFiddle) using this CSS:
.triangle {
width: 0;
height: 0;
border-top: 0;
border-bottom: 30px solid #666699;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
}
And this HTML:
<div class="triangle"></div>
This makes a triangle, but the diagonal lines are jagged and pixelated. How can I make them smooth? (I was able to smooth them out in Safari and Chrome by making them dotted, but that broke the triangles in Firefox and IE.)
For Firefox you can add -moz-transform: scale(.9999); to make smooth edges. In your case:
.triangle {
width: 0;
height: 0;
border-top: 0;
border-bottom: 30px solid #666699;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
-moz-transform: scale(.9999);
}
Will do the trick.
