[Idea] Form with css method

Lately, I was read about css variables and I had mixture an idea.
What about allowing to dynamically change css applied to an page, without javascript?
Simple html element, created with form tag, method css. Input’s name’s would be css property. Action will be assembly with this elements:

  1. CSS Rule id - because, when user decided to change css, we won’t generate new rule, but replace existing (it cannot contains question mark)
  2. Question mark
  3. Selector

Also, allow apply set-input tag (new tag) to option tag. It contains input name and new value. For example:

Also, you could create css protocol to change css by click on link (without form and without javascript).
