Letters in headings are too close to each other

[hmosvoll]

Describe the bug

The negative letter spacing cause some letters to have no spacing at all.

To Reproduce

• Go to the Datepickers page.
• Take a look at the h2 "Initial value"

Possible fix
Reduce negative margins and use em for dynamic spacing based on font size, such as letter-spacing: -0.02em;
Btw why does this only apply to h1 and h2?

I agree, on certain words/letter combos it makes it harder to read, maybe especially on h5's.
@stepandersen should probably give his 2 cents first though
