Blank line in start

blank line - above the code snippet . . My sample code

	font-weight: 600;

No. We purposely do not modify your content. If someone wants space at the beginning, they can have it.

You could write a tiny plugin:

Just before the highlighting trim the whitespace yourself by modifying the DOM…

I already offered the solution: https://github.com/highlightjs/highlight.js/issues/3054#issuecomment-801916563

IF you want to strip the space then either use a plugin (see documentation) OR simply loop over the DOM yourself and strip the space from every code block before you even ask us to highlight them.
