#150 Finger Heart - 99.9% but diff is pure black

[richardacre]

Below code is 100% black in the diff, but scores only 99.9%, even though I've taken out all the "q" units and gone with integer px's

<p a><p><p b><style>*{background:#4F77FF;position:fixed}[a]{padding:100;margin:-58}p{padding:25 50;margin:92;border-radius:25px;background:#1038BF}[b]{padding:50 25

even the below, being explicit about the html closing tags, margins and nesting etc still only hits 99.9%

<div a></div><div></div><div b></div><style>*{margin:0;background:#4F77FF;position:fixed}[a]{padding:100;margin:-50}div{padding:25 50;margin:100;border-radius:25px;background:#1038BF}[b]{padding:50 25

Edit: So if I rearrange the P tags in the first example I can get it to report 100%. Something to do with the z-index, border radius and anti aliasing?
