/* defualt light color */
:root{
--bg-color: white;
--text-color: black;
}
/* dark color */
@media (prefers-color-scheme: dark){
:root{
--bg-color: black;
--text-color: white;
}
}
body{
height: 100vh;
background-color: var(--bg-color);
color: var(--text-color);
display: flex;
justify-content: center;
align-items: center;
transition: background-color 0.3s, color 0.3s;
}Normally, :root defines the default light mode with –bg-color set to white and –text-color set to black. Similarly, the :root inside the @media (prefers-color-scheme: dark) query switches to dark mode by setting –bg-color to black and –text-color to white.
