I'm using description lists for several different purposes in something I'm writing. I would like to somehow define these lists differently so that I could apply different formatting or style to the different types. In HTML/CSS I would use the "class" attribute to do this. Is there something similar that can be done in LaTeX? The only thing I could think of was to make sort of a wrapper \NewDocumentCommand or environment that would get the list passed to it as an argument.
EDIT:I meant the description environment. So sometimes I might want the descriptions on the same line as the items, other times offset on the next line. I know how to do this, but I don't want to have to do it individually for each list. The project may have as many as 240 description lists of three different types.
I wanted to keep things flexible in case I had different ideas, but maybe I'm applying too much of an HTML/CSS mindset -- there I would use class attributes even if I had no specific plans to style things differently, just in case I wanted to do it later.
