HTML Guide

Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.

The <article> element can be used to define complete, self-contained compositions of a document, for example blog posts. Consider using a heading element (any of <h2> to </h6>) to present each article.

Example:

<h1>Our blog</h1>
<article>
  <h2>How to validate accessibility</h2>
  <p>Use Rocket Validator for a in-depth scan</p>
</article>
<article>
  <h2>How to monitor sites for accessibility</h2>
  <p>Define schedules in Rocket Validator</p>
</article>

Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).

headings

The HTML <h1> to <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 <section>, and <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>

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

The <section> element can be used to define sections of a document, like chapters, tabbed content, etc. Consider using a heading element (any of <h2> to </h6>) to present each section. Example:

<h1>All about guitars</h1>
<section>
  <h2>Guitar types</h2>
  <p>Acoustic, electric, classical... we have them all!</p>
</section>
<section>
  <h2>Amplifiers</h2>
  <p>Analog, digital, portable...</p>
</section>

The “article” role is unnecessary for element “article”.

The article role indicates a section of a page that could easily stand on its own on a page, in a document, or on a website, is implicit when using the <article> tag.

This role indicates a section of a page that could easily stand on its own on a page, in a document, or on a website. It is usually set on related content items such as comments, forum posts, newspaper articles or other items grouped together on one page. It can be added to generic elements like <div> to convey this role, for example:

<div role="article">
  <h2>Heading</h2>
  <p>Content...</p>
</div>

Instead of using this role, it’s preferrable to use the native <article> element like this:

<article>
  <h2>Heading</h2>
  <p>Content...</p>
</article>
