How to make a 2 line heading with GitHub Markdown?

Question

I want to know how to make a markdown heading over 2 lines.

I tried using 2 headers, but that displays 2 headers rather than 1 multiline heading. For example,

# :emoji:
# Heading

displays,

:emoji:

Heading

Answer 1

You can break any line in GitHub Markdown with the <br> element. This also applies to headers. Hence, the following can be done:

# :emoji:<br>Heading

:emoji:
Heading

Notice how the line break is closer; GitHub will not add the heading underline between lines.
