How does Tailwind apply styles with the dark variant?
Given the Tailwind class dark:bg-gray-800, what happens when the user switches to dark mode in their system settings?
AThe background color never changes because Tailwind does not support dark mode.
BThe background color changes to gray-800 automatically without any extra setup when the system is in dark mode.
CThe background color changes to gray-800 only if the <code>dark</code> class is present on the <code>&lt;html&gt;</code> or <code>&lt;body&gt;</code> element.
DThe background color changes to gray-800 only if the element has a <code>dark</code> attribute.

What color will the text be in dark mode?
Consider this HTML snippet with Tailwind classes:
<div class="text-black dark:text-white">Hello</div>

What color will the text be when the page is in dark mode and the dark class is on the <html> element?
Tailwind
<div class="text-black dark:text-white">Hello</div>
AThe text will be white because the dark variant overrides the base color in dark mode.
BThe text will be black because the dark variant does not override the base color.
CThe text will be gray because Tailwind blends colors in dark mode.
DThe text will be invisible because both colors conflict.
