[NFBCS] CSS

[Michael Ausbun]

Greetings,
I'm curious what non-visual techniques folks use when working within CSS. Is determining the CSS' final output/user experience largely dependent on a reader/sighted person? Are there generally accepted best practices for CSS; such as ensuring all elements have a particular margin/padding/etc?
Trying to figure out the most efficient way to produce visually-appealing or inclusive design when using CSS. Writing CSS is no problem; just not sure about the checking, without using a reader.
Much appreciated!
Respectfully,
Michael
