CSS - Syntax Highlighting

Source

I found this on [Reddit](Guide: adding icons to notes based on tag : r/ObsidianMD (reddit.com)), posted by user pillowpotion.

Setup

Go to Settings, Appearance, and scroll all the way down to the CSS snippets section. You might already have some there, or not. It does not matter for us.

Click on the folder icon. This should open the local folder containing the snippets. Create a new file and give it a name that makes sense to you. For example, syntax highlighting.css. Make sure that the file extension is css. If you don't see your file extensions, click on View, Show, and File name extensions (in Windows Explorer).

Now open the file and copy the CSS code below into it. Save the file, go back to Obsidian and refresh the list of snippets. Enable this one, and that should do it. If it does not, you may have to restart Obsidian.

Result

This snippet lets you customize the colors of elements in your code blocks.

Code

body {
	--code-white-space: pre-wrap;	 /* type: variable-select, default: pre-wrap, options: normal, nowrap, pre, pre-wrap, pre-line, break-spaces, collapse balance, preserve nowrap) */
