How to make h1, h2, h3 tags?

i am confused. i have a little bit of experience. my last wordpress blog i attempted, i could easily change a heading to h1, h2, or h3. can someone explain to me how to do that on this theme. Thank you.

Depends on where you’re trying to do that.

In a post you just use normal HTML. Headlines/titles are already H1.

In sidebars and indexes for stories, headlines are usually h2 and h3, as there should only be one H1 per page.

For home page, for a site description, just make a text box and wrap a site description in h1 tags; for custom CSS apply a style class like
<h1 class="homeh1">My Neato Description</h1>
