Typinator snippets used to write CSS. You need to type "c" in the quick search to filter (activate) those snippets.
I don't assign short abbreviations for most of them because I don't use abbreviations. I tend to forget them. For that, my strategy is to simply type the letter "c" on the quicksearch so that all the snippets of the CSS language will show up there. I will then quickly select or further filter them.
if you want use abbreviations, you can change them to shorter words or phrases.
As to the function of each of the snippets, I have added extensive descriptions on each of them. You will get the descriptions when you call them. You can also read the descriptions by opening each of them.
