If you scroll down to the bottom, you’ll also find where you can set a custom HTML anchor for the heading block. You can read more about how to set an HTML anchor in this post.
And, just as with all blocks, you can set a custom CSS class for the block.
Why use a heading block?
Organizing your posts using various header levels is good for SEO and also helps with readability as people tend to scroll through blog posts looking for the content they want vs. sitting down for a good, long read as with an essay in a print article or book.
Still, you can always choose to disregard using headings if it’s appropriate for your individual piece regardless of what your SEO plugin might tell you.
Tip: Reserve the H1 heading level for your post title. Use H2 and below for sections of your post.
