I'd prefer plain style without shadows.
/*
Diagram and ASCII ART styling for Jekyll
(and other markdown parser that appends a .language- prefix)
*/
.language-ascii-art {
display: inline-block;
font-family: "Lucida Console", Monaco, monospace;
letter-spacing: -0.2em;
line-height: 0.8em;
}If you look at the style, it's essentially just moving text characters closer to each other.

Btw, no shadow example is added now.
