delete color-scheme in head-html

[tcitry]

This is a suggestion about #387, just have a look.

[alex-shpak]

Hm, perhaps we should set it to light/dark theme background color?

[tcitry]

You mean BookTheme in config.toml ? I set it auto, and preferred_color_scheme with giscus. so, there still have problem when I in dark mode in macOS.

[alex-shpak]

Perhaps

<meta name="theme-color" media="(prefers-color-scheme: light)" content="#ffffff">
<meta name="theme-color" media="(prefers-color-scheme: dark)" content="#343a40">

[tcitry]

I tried on my local, not fixed with <meta name="color-scheme" content="light dark"> 😅

[alex-shpak]

But remove <meta name="color-scheme" content="light dark"> and add snipped I posted.

[tcitry]

yes, it works.

[alex-shpak]

But this does not? I would expect that to work

<meta name="color-scheme" content="light dark">
<meta name="theme-color" media="(prefers-color-scheme: light)" content="#ffffff">
<meta name="theme-color" media="(prefers-color-scheme: dark)" content="#343a40">

[tcitry]

No, its not work. I am confused too.

[tcitry]

Maybe it was a problem with giscus, and fixed with https://github.com/giscus/giscus/commit/15857d093d6115db81582cc56e01f2ce6c5ff18c, so this could be closed.
