The CSS transition-delay property specifies how long to wait before starting a property transition. In the given CSS code, the transition-delay is set to 2s.
* CSS Transition Properties:
* transition-property: Specifies the CSS property to which the transition is applied (font-size in this case).
* transition-duration: Specifies how long the transition takes (4s).
* transition-delay: Specifies the delay before the transition starts (2s).
Example:
* Given HTML:
<div id="delay">Hover over me</div>
* Given CSS:
#delay {
font-size: 14px;
transition-property: font-size;
transition-duration: 4s;
transition-delay: 2s;
}
#delay:hover {
font-size: 36px;
}
Explanation: When a user hovers over the element with id="delay", it will wait for 2 seconds before the transition effect on font-size starts.
