h1 tag used more than once

Question

In the course example I found an h1 tag use more than once. Isn't it a bad practice?

<article>
<h1>Welcome</h1>
<section>
<h1>Heading</h1>
<p>content or image</p>
</section>
</article>

Answer 1

Multiple <h1> elements are valid regarding Html5 rules, but good practice regarding semantical meaning is to use only one <h1> per html document for better SEO (search engine optimization) ^^

Answer 2

It's not a bad practice at all. Since you are using articles and sections in a web page you can use h1 tag more than once in each sections and each articles.

Answer 3

you can use h1 tag as many times as you need.....no limit
