// tailwind.config.js
{
  theme: {
    transitionProperty: { // defaults to these values
      'none': 'none',
      'all': 'all',
      'color': 'color',
      'bg': 'background-color',
      'border': 'border-color',
      'colors': ['color', 'background-color', 'border-color'],
      'opacity': 'opacity',

The default configuration generates the following CSS:

/* base styles for the default transition duration, timing function, and delay (when they differ from the CSS defaults) */
*, *::before, *::after {
  --transition-duration: 250ms;
  /* when the default timing function is a value other than "ease": */
  --transition-timing-function: [default-timing-function];
  /* when the default delay is a value other than zero: */
  --transition-delay: [default-delay];
}

/* configurable with the "transitionProperty" theme object */
.transition-none {
  transition-property: none;
  transition-duration: 250ms;
  transition-duration: var(--transition-duration);
}
.transition-all {
  transition-property: all;
  transition-duration: 250ms;
  transition-duration: var(--transition-duration);
}
.transition-[property-key] {
  transition-property: [property-value];
  /* when the default duration is a value other than zero: */
  transition-duration: [default-duration];
  transition-duration: var(--transition-duration);
  /* when the default timing function is a value other than "ease": */
  transition-timing-function: [default-timing-function];
  transition-timing-function: var(--transition-timing-function);
  /* when the default delay is a value other than zero: */
  transition-delay: [default-delay];
  transition-delay: var(--transition-delay);
}

/* configurable with the "transitionDuration" theme object */
.transition-0 {
  --transition-duration: 0ms;
  transition-duration: 0ms;
  transition-duration: var(--transition-duration);
}
.transition-100 {
  --transition-duration: 100ms;
  transition-duration: 100ms;
  transition-duration: var(--transition-duration);
}
.transition-[duration-key] {
  transition-duration: [duration-value];
  /* when the default duration is a value other than zero: */
  --transition-duration: [duration-value];
  transition-duration: var(--transition-duration);
  /* when the default timing function is a value other than "ease": */
  transition-timing-function: [default-timing-function];
  transition-timing-function: var(--transition-timing-function);
  /* when the default delay is a value other than zero: */
  transition-delay: [default-delay];
  transition-delay: var(--transition-delay);
}

/* configurable with the "transitionTimingFunction" theme object */
.transition-linear {
  transition-timing-function: linear;
}
.transition-ease {
  transition-timing-function: ease;
}
.transition-[timing-function-key] {
  transition-timing-function: [timing-function-value];
  /* when the default timing function is a value other than "ease": */
  --transition-timing-function: [timing-function-value];
  transition-timing-function: var(--transition-timing-function);
}

/* configurable with the "transitionDelay" theme object */
.transition-delay-0 {
  transition-delay: 0ms;
}
.transition-delay-100 {
  transition-delay: 100ms;
}
.transition-delay-[key] {
  transition-delay: [value];
  /* when the default delay is a value other than zero: */
  --transition-delay: [value];
  transition-delay: var(--transition-delay);
}

/* configurable with the "willChange" theme object */
.will-change {
  will-change: contents;
}
.will-change-auto {
  will-change: auto;
}
.will-change-[key] {
  will-change: [value];
}

Which you can then use in your HTML like this:

<button class="bg-gray-600 hover:bg-gray-500 transition-bg">
  Hover me for a lighter background
</button>

<button class="bg-gray-200 hover:bg-gray-900 text-gray-900 hover:text-gray-200 transition-colors transition-500 transition-linear">
  Hover me to invert colors
</button>

Note: The transitionDuration, transitionTimingFunction, and transitionDelay theme objects accept a default key that doesn’t generate any class; it is used to define a custom property on all elements and pseudo-elements (*, *::before, *::after) if the value differs from the CSS-defined default. These custom properties are then used to set actual properties on elements that have a transition-[property] or transition-[duration] class, so that you don’t have to define a duration, timing function, or delay every time.
