Why the h1 in article is bigger than the h1 in section?

Answer 1

Did you mean bigger in font-size? It is relative, depending on your CSS styling for h1 inside article or section tag. You can set h1 inside section bigger than h1 under article tag. For example:

<article>
<h1>Header 1 in article</h1>
<section>
<h1>Header 1 in section</h1>
</section>
</article>

<style>
article h1 {
font-size: 32px;
}

article section h1 {
font-size: 36px;
}
</style>

Now, h1 in section bigger than h1 in article.
