HTML

Question

Why in HTML <h7> doesn‘t exist?

Answer 1

The HTML spec defines 6 headings. Browsers recognize 6 headings. If you start using <h7> and so on, then you'll be using an invalid element.

If you find yourself needing an <h7> then you should probably take a look at how you're structuring your site. Not every single title deserves a heading element.

Thank

Answer 4

Because h6 has the same size as normal font (maybe a little smaller). As you may know, h6 < h5 < h4 < h3 < h2 < h1. If you want smaller font, costumize it in CSS:

.selected-text {
font-size: ...; //Don't forget to put the measuring unit
}

The default is 12px or 1em.

Good luck!
