transition-delay
CSS transition-delay Property
The transition-delay CSS property specifies when the transition effect should start.
The transition-delay property is one of the CSS3 properties.
The default value is 0s which means that the transition effect starts immediately.
The time offset which is specified with the transition-delay property offsets the transition animation by the specified amount. The offset can be a negative value as well. When a negative time offset is used as a value for the transition-delay property the transition will execute the changed moment of the property, but it will appear that the execution has started at the specified offset.
The value can be either a valid time value defined in seconds or milliseconds or a comma-separated list of time values specified for a single element. When we have a comma-separated list of property names, this list is commonly mapped to the values of other transition-related properties (transition-duration, transition-timing-function, transition-property).
For maximum browsers compatibility extensions such as -webkit- for Safari, Google Chrome, and Opera (newer versions), -moz- for Firefox, -o- for older versions of Opera are used with this property.
