Lesson 1 - Headings, Paragraphs, and Horizontal Lines

Heading level 2

Since your title (defined at the top of the file) is your heading level 1, you should never use another heading level 1 in your body.

Heading level 3

The number of pound signs determines the heading level.

Heading level 4

It's also important not to skip heading levels. Don't jump from a 2 to a 4 or similar.

Paragraphs

You'll notice that I am putting blank lines between headings and plain text. This is necessary, or they won't render correctly.

It's also important to put a blank line in between each paragraph. See what happens without it: This is supposed to be a new paragraph, but it isn't.

Horizontal lines

Sometimes you want to insert a visual break in your text that isn't just a new paragraph. You can use three dashes to create a horizontal line:

This text will be below the line.
