Titles

As we started writing a markdown document, we need to add a title and some sub-headers.

Markdown supports two styles of headers, Setext and atx.

Setext-style headers are “underlined” using equal signs (for first-level headers) and dashes (for second-level headers). For example:

This is an H1
=============

This is an H2
-------------

Any number of underlining =’s or -’s will work.

Atx-style headers use 1-6 hash characters at the start of the line, corresponding to header levels 1-6. For example:

# This is an H1

## This is an H2

###### This is an H6

Optionally, you may “close” atx-style headers. This is purely cosmetic — you can use this if you think it looks better. The closing hashes don’t even need to match the number of hashes used to open the header. (The number of opening hashes determines the header level.) :

# This is an H1 #

## This is an H2 ##

### This is an H3 ######

Here's a quiz about markdown titles.

Select the valid headers:

• [x] # hello
• [ ] #hello

Headers need space between the hash characters and the text.

Select the valid headers:

• [ ]

  ########
  

• [x]

  =======
  

Only '=' and '-' are accepted for underlining an header.
