Font-size of h1 is shown different (36px vs. 24px), when it is part of HTML-element "main" or "section"

My HTML-file contains the following code: ... <main> 

<h1>Headline</h1>
Some Text

... </main>

When I change "main" to "section", the font-size changes from 36px to 24px (this is reported by webdevelopper), but only for "Headline", for "Some Text" font-size remains unchanged. In CSS I have "body {font-size1: 1.1em;}", no other rules for font-size.

Can You explain this and/or give help? Thanks Andreas

I see some font-size rules in the default builtin html.css file.

Thanks for prompt answer. The link is somewhat helpful. I don't understand the rules completely, but I suppose, there are modifications along with the new version 63.0.1, which cause what I see in my webpage. So, it is as it is.
