Wait, #Sharkey doesn't support the $crop [#mfm either? I'll bet at ruins a bunch of old stuff.
Oh well; that's what I get for trusting a screwy undocumented markdown language without a reference spec. If I cared about consistency, I'd find something that lets me post raw CSS and HTML.
After looking at some of the source code in #Sharkey's implementation of #MFM, I discovered the details of the $[border decoration.
It accepts a width property for how thick the border should be (don't specify units)
There's a radius property for corner roundness (don't specify units)
You can specify a color with a 3, 4, or 6 digit hex code (don't put a hash sign first)
You can specify style where the options are ['hidden', 'dotted', 'dashed', 'solid', 'double', 'groove', 'ridge', 'inset', 'outset'] with a default of solid if you try to put in something else.
The noclip keyword doesn't have any properties. If you don't say noclip then it will add overflow:clip to the border which hides stuff inside it if it doesn't fit.
@ulysia the main limitation I run into is that while you can layer as many things as you want by tweaking their position, it'll still take up the space that the content would have if you hadn't moved it. Hopefully that makes sense, mfm is weird.
