Headings h1 and h2 are interchanged

[kuleszdl]

First of all, thank you a lot for making this great theme available! How,ever I noticed that the style of the headings seems to be a bit off:

Describe the bug
Headings of level h1 appear smaller than those of level h2.

To Reproduce

Build a site using both headings, e.g.:

# Heading 1

text

## heading 2

text

or

Heading1
=======

text

Heading 2
-------------

text

Expected behavior
Heading 1 should be larger than heading 2.

Desktop (please complete the following information):

• OS: Linux
• Browser Firefox
• Version 60.x (ESR)

Additional context
Could be worked around by using the syntax the other way round, however, switching themes later would be cumbersome.

Whoopsie, yeah. I’m using h1s for the title and should apply the same styling (or font-size, at least) in the article body too.
