* fix: take out [data-scheme="dark"] from :root
Taking out the [data-scheme="dark"] from :root allows us to fix the
precedence of CSS when the [data-scheme="dark"] is placed in the <html>
tag. This is needed in order to make the dark styles accesible from the
<html> elment, this will allow us to change the vertical scrollbar
styles following the dark and light schemes.
* change document.body.dataset.scheme to document.documentElement.dataset.scheme
When the dark mode is on or when the light mode is on, the
[data-scheme="light"] or [data-scheme="dark"], respectively, will be
placed in the <html> tag. Allowing us to access the dark and light color
schemes from the <html> to change the vertical scrollbar styles
according to the current color scheme.
* feat: change the page vertical scrollbar styles
This change will make the vertical scrollbar styles to follow the dark
and light color scheme modes. Also, this change will make the vertical
scrollbar to look consistent in both, Chromium and Firefox.
* make the scrollbar-track background-color transparent
The body has this transition: 'transition: background-color 0.3s ease
0s'. Making the scrollbar-track background-color transparent allow us to
appreciate that transition in the scrollbar-track when switching the
background-color.
* Move [data-scheme=dark] back to :root block
* fix(comment/waline): detect dark mode from html tag
* feat: apply custom scrollbar style to all elements
