htmx 4.0 is under construction — migration guide

The htmx.config.defaultSettleDelay option controls how long htmx waits between the swap phase and the settle phase (when CSS transition classes are removed).

Default: 1 (1 millisecond)

Example

htmx.config.defaultSettleDelay = 100;
<meta name="htmx-config" content='{"defaultSettleDelay":100}'>

Increase this value if CSS transitions are not completing before htmx removes the transition classes.
