Hi, Jermayn

Separating presentation and content is one of the main directions in which the W3C goes. It basically means using HTML for structural markup and CSS for styling/layout.

Using h1 tags for visual presentation goes against the grain. You can, instead, label a heading div and apply styles to it.

Using HTML for structure and CSS for styling is a good habit to have, because people with disabilities rely on software that interprets HTML markup, such as headings, lists and such.

You don't want to redo your websites to make them accessible to comply with already functioning Web accessibility law, right?

Using hx for presentation (for increasing font-size and making text block elements) is a pretty grey area now with the search engines, too. If you overuse or abuse it, you may have issues (ranking or indexing), with Google, at least.

Though I don't see how one would create a page on two different topics right now, I'll add h1 to the list.

At the moment, h1 is used automatically for page titles (the one you see as "Page title" when creating pages).

Cheers.
