I cannot reproduce, converting the following html
Code:
<!DOCTYPE html>
<html>
<head>
<title>test</title>
<meta charset="utf-8" />
</head>
<body>
<p style="font-size: 0.8rem">Hello i love yuou</p>
</body>
</html>
results in the following stylesheet.css (with font rescaling turned off)
Code:
.calibre {
display: block;
padding-left: 0;
padding-right: 0;
margin: 0 5pt
}
.calibre1 {
display: block;
font-size: 0.8rem;
margin: 1em 0
}
