Hello,
I have seen that in the CSS stylesheets for the stacks, e.g. integrity or renew, the headings h1, h2, etc. are defined with percentage font sizes, e.g.
h3, .h3
{
font-size: 228.5%;
}
Is there any benefit of doing so instead of using absolute px values, e.g. font-size: 64px; I assume that one “advantage” could be that the headings scale, when changing the body font-size, but this is also an effect, someone might not want to have.
Or in other words, is there any disadvantage when using px value heading sizes?
