HTML issues tagged as h1.
<h6> elements represent headings for the different sections of a document, where
<h1> is the highest section and
<h6> is the lowest. Headings are specially important on screen readers as they give a quick overview of the contents of the different sections in the web page, so although it’s technically correct (not an error) to use a
<h1> in this way:
<section class="about"> <article> <h1>Article heading</h1> <p>Lorem</p> </article> </section>
this will raise a warning as it would be preferrable for example to leave the
<h1> for the heading of the
<h2> for the heading of the article, like this:
<section class="about"> <h1>About heading</h1> <article> <h2>Article heading</h2> <p>Lorem</p> </article> </section>
