Handy CSS
October 31, 2022
Here is the css file that I include in my theme ( one of many, actually. ) This file pre-defines a lot of CSS options as classes, which makes them much easier to use. Include this file in your theme header, and these classes will display properly in the Gutenberg WordPress editor. In fact, I am using them now.
/*
* additional quick classes that should be part of css
* many of these display correctly in Gutenberg

A lot of this is pretty repetitive, like all the width specifications. But it is handy to have many useful widths pre-defined. Pre-defining useful css classes and then using them is the opposite of the way most web designers work. Most web designers make up new classes as the need arises, willy-nilly, with the result that you end up with dozens of redundant classes that all do the same thing, * or more likely, almost but not-quite the same thing. The end result is hundreds of classes overall, if not thousands. The css gets huge, until eventually the poor program that has to parse the whole mess crashes. The worst case of this is epubs ( which are really self-contained websites ) generated by the Calibre program. Oh my god!
* Did you notice I'm being redundant?
A benefit of pre-defining CSS and then sticking to it is that you end up with much more consistent formatting. Have you ever wondered why much of the internet looks like it was done by a third-grader? In fact, this is the way CSS was intended to be used, and most web designers are actually using it wrong!
