Dark mode: text selection is barely visible

[laenzlinger]

Description

The default browser ::selection highlight is nearly invisible against PaperMod's dark background. No ::selection styles are defined in the theme, so it falls back to the browser default (typically a blue that blends into the dark background of #1d1e20).

This affects all major browsers (Chrome, Firefox, Safari, Edge) since their default selection colors have poor contrast against the dark theme.

Suggested fix

Add ::selection styles for dark mode in the theme CSS:

.dark ::selection {
    background: rgba(178, 134, 252, 0.4);
    color: #e2e8f0;
}

Workaround

Add the above CSS to assets/css/extended/.
