Styling BBEdit’s Markdown Preview
What’s not so clear is how to style your filtered Markdown content into markup that doesn’t look like a webpage presented in Netscape 3. Thankfully this situation is easy to rememdy:
Create the folder
~/Library/Application Support/BBEdit/Preview CSS (if it doesn’t already exist) and drop in as many stylesheets as you please. These stylesheets will be accessible from BBEdit’s preview window’s CSS popup menu.
