Data Lock Secure: Hairline Animation

Data Lock Secure

A padlock in front of an isometric data block snaps its shackle shut on a spring, then an accent perimeter ring settles around both. Hairline SVG with CSS translate and scale.

Also known as: security lock animation, encryption animation, hairline isometric.

Customizing this snippet

Color: set --hln-color on the element or a parent. Currently previewing #3b82f6.
Base size: set --hln-size. Every other dimension is in em, so the whole thing scales together. Currently previewing 16px.
Speed: change the duration on the transition or animation shorthand. 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.
