About HTML5 Tags
In HTML 5, we have a tendency to had the heading tags from to for outlining a document define. every higher range tag becomes a baby of the lower range tag. for instance, the subsequent structure...
<h1>HTML 5</h1>
<h2>Specs</h2>
<h3>Section Tags</h3>
<h4>Section</h4>

<h6>HTML 5</h6>
<section>
<h3>Specs</h3>
<section>
<h2>Section Tags</h2>
<section>
<h1>Section</h1>
</section>

Notice that the h3 tags became the kids of the highest h6 tag, the h2 tags square measure currently youngsters of the h3 tag, and also the h1 tag is fostered by an h2 tag.
What it means?
This decree mustn't happen. Not solely will it build things confusing, however additionally ruins the show for search engines and user agents alike.
For search engines, headings of a better rank (h1, h2) may well be overrun by headings of a inferiority (h3-h6). you recognize however vital these headings square measure for SEO, right? (If not, browse this text on mistreatment headings to optimize your web log post). Search engines assign worth to superior headings, and classify content supported these headings. currently if you have got multiple h1s, that solely serves to confuse the search engines. Secondly, h1s ought to be most keyword-healthy, followed by h2s, h3s and then on. you are not doing yourself a favor by breaking the chain of command flow of those headings!
Most user agents haven't adopted these specifications nonetheless. They in all probability will not any time presently, however the face remains that if confronted with these new tags, the user agents can merely ignore them. that the document define you have outlined with these new tags are going to be thrown out of the window, and also the agents can merely return to the recent ways that, and use the default h1-h6 theme for drawing up the table of contents, or otherwise interacting the page.
What must you do?
This doesn't mean you should not use the hypertext mark-up language five section tags for outlining structure. If you as a developer need to produce a purposeful document structure, use the h1–h6 parts to precise document structure. don't rely on the HTML5 document define. By all suggests that use the HTML5 section parts, however don't rely on them to convey a purposeful structure. If at some purpose within the future the HTML5 document define ceases to be a fiction, you may be coated because the use of h1-h6 is backwards compatible.
The hypertext mark-up language five specification has an equivalent recommendation for you.
Sections may contain headings of any rank, and authors are strongly encouraged to use headings of the appropriate rank for the section’s nesting level.
