December 19, 2024 -
I have several themes for my website, and I use JS to switch between them. Each theme has its own style. the other styles use regular color backgrounds, so I just used "transition: background-color .3s ease", but when I move into the theme with the linear-gradient background, it's really abrupt with no transition.
How can I implement a transition to make it less sudden?

You register the gradient stops as custom properties and then you can transition them. background: linear-gradient(var(--c0), var(--c1)); transition: .3s; /* ease is the default, no need to specify it */ transition-property: --c0, --c1 For the no gradient themes, --c1 is set to --c0. .gradient-theme { --c0: gold; --c1: purple } .no-gradient-theme { --c0: hotpink; --c1: var(--c0) }
