New themeCopy Anchor Link

If you are going to update the package to the latest version, you will encounter a problem that says uilab-core/theme.css is not found or something like that.

You need to update your css file like below

@import "uilab-core/styles.css";
@import "uilab-core/neutral.css";

/*
	This is the old source, you can remove this line
	@import "uilab-core/theme.css";
*/

If you don't like the new theme, you can always use the old one with this line

@import "uilab-core/styles.css";
@import "uilab-core/legacy.css";
