Installing the Lizardmen Zettelkasten theme but the result is not what it should be.
Yellow text (instead of black in light mode of white in dark mode) in light mode this is on white background: not readable.
By hovering a link: content of links is not shown. No underlining to.
I like to use your theme though.
As @Obsidandnancy said, I went ahead and created a brand new vault, followed by installing the theme. Seems to work fine. It could be a plugin interfering with it or you might have something in the CSS snippets folder that is interfering.
