Deploy Status Border: CSS Border Animation

Deploy Status Border

A deploy card whose dashed border marches while it builds, then closes into a solid green line with a glow as the status flips to Ready. One SVG rect animates dash length, offset and color.

Also known as: status border animation, build status card css, deployment card animation, dashed border loading css.

Customizing this snippet

Color: set --bdr-color on the element or a parent. Currently previewing #3b82f6.
Base size: set --bdr-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.
