Similar to the contextual text color classes,easily set the background of an element to any contextual class. Background utilities do not set color,so in some cases you’ll want to use .text-*utilities.

By adding a .bg-gradientclass,a linear gradient is added as background image to the backgrounds. This gradient starts with a semi-transparent white which fades out to the bottom.
Do you need a gradient in your custom CSS? Just add background-image:var(--bs-gradient);.
