text-decoration-line: blinkLimited availability

Not yet supported in all major browsers — check the table and provide a fallback.

Discouraged: Browsers may ignore the blink value. Use instead: Animations (CSS)

How to use

Support is still inconsistent across browsers. Use feature detection and test carefully.

Example

Full syntax and examples are on MDN — see the links below.

Feature detection

CSS · check before using
@supports (text-decoration-line: blink) {
  /* styles that rely on text-decoration-line: blink */
}

/* or in JavaScript */
if (CSS.supports("text-decoration-line", "blink")) {
  // use it
}
