Is there a way to make pretty, colorful blockquotes in LateX
like this?
This might be a duplicate of How can I make blockquotes in LaTeX, like Markdown, but I don't like the ugly gray blockquote which that produces.
I know that answer lets you choose different colors other than gray, but is there a way to add fancy borders
like this
or like on the other StackExchange websites (Math comes to mind for me).
tcolorbox, where you can use any color you wish. This answers seems to solve your problem. Seetcolorboxdocumentation, there is big number of examples. – Zarko May 21 '16 at 16:28
