Should be added

[notsure]

Functions

• calc-em --> and everywhere else the fallback size is 16px before it was stored in config.$config--font-size; this could be reintroduced.

Mixins

Extends

• border-gradient (ivcolar - renders a border with a colourful gradient)
• loading-text (motorex - displays a sekelton loading indicator)

General

• Deprecation warnings into changelog and add the version to each @deprecated
• loading indicator: as overlay, fullwidth, inline ... --> could also be a component
• Should we move as many variables from SASS variables to CSS variables?
  • major benefit is that everything can be overwritten
  • biggest disadvantage is that if css variables are deleted, the code fails silently

-- > are there other cool mixins or functions we could use?
