it was netscapes take on style sheets, using javascript instead. it gave us the with expression, so you could write either this:
tags.H2.color = "red";
tags.H2.fontSize = "16pt";
tags.H2.marginTop = "4cm";
or you could write this:
with (tags.H2) {
color = "red";
fontSize = "16pt";
marginTop = "4cm";
}
