PDF export: change inline title css

[m.scheminger]

I’m trying to style my pdf exports and change the inline title’s css but couldn’t manage to. It now looks like this:

However, I want the title to be bigger than Heading 1.

Tried targeting it like this:

@media print {
    .inline-title {
    font-size: 2.5em;
    }
}

Didn’t work though. Does somebody have a solution?
