Frosted glass
A translucent pane over slowly moving color.
Glassmorphism Login Form
A frosted sign in card with glass inputs and a solid button, floating between two slow orbs. Fields glow on focus with :focus-within, and the button gets a shine sweep on hover.
Also known as: glassmorphism login form html css, glass login page css, frosted login form.

}Customizing this snippet
- Color: set
--gls-coloron the element or a parent. Currently previewing#3b82f6. - Base size: set
--gls-size. Every other dimension is inem, so the whole thing scales together. Currently previewing16px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
