Axiom is a set of axiomatic CSS mixins.
1: Consider the following CSS property name and property value domains.
| key | value |
|---|---|
| display | block |
| flex | |
| inline-block | |
| inline | |
| position | relative |
| absolute | |
| fixed | |
| font-weight | bold |
| font-style | italic |
| … etc |
In many cases, the value itself is representative enough and even unique across all property domains. When you see value like block it is in most cases means display: block. So the first idea is to omit keys in cases when they are obvious. CSS does not support «boolean» or «flag» values. This is a place for a mixins, like .block.
2: We often use properties in a composition. Like when you need some special left value,
you often need also a top. Or when you specify width you may want to specify height as well in some cases. Sometimes you need block with line of text inside, so you specify both height and line-height of the same value.
Mixins, which provide adequate abstractions, like .pos(@top; @left) or .wh(@width; @height) (with a little help of reasonable defaults) may be handy.
3: Using axiomatic mixins allow to write short, well-composed and even poetic definitions for elements. It is a good ground for more high-level mixins.
