On Mac Power Users, co-host David Sparks recommends using the code formatting in Markdown for notes and annotations. I tried that but at first it didn’t work for me; I need my notes and annotations to really pop – jump out at me when I’m scanning a document.
Solution: Very simple CSS to render code with a yellow background:
* {
font-family: "Menlo";
}
pre, code {
background-color: yellow;
}
