Quick Reference
The transition-duration property specifies how long the transition effect will take to complete, and is defined in seconds (s) or milliseconds (ms).
The following will animate the width, on hover, after a delay of 250 milliseconds, over the course of 0.4 seconds, using ease-in-out.
div {
width: 50%;
transition-property: width;
transition-duration: 0.4s;
transition-timing-function: ease-in-out;
transition-delay: 250ms;
}
div:hover {
width: 100%;
}
Note
The transition is put on the original element and NOT the element that will cause the change, such as a :hover.
Default

Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.
document.getElementById('my_div').style.transitionDuration = '0.4s';
<button onclick='my_function()'>Click Here</button>
<script>
function my_function() {
document.getElementById('my_div').style.transitionDuration = '0.4s';
}
</script>
CSS Notes:
- The “inherit”, “initial” and “unset” keywords can be used with any CSS property to set its value
- In CSS there are many ways to express a color value in a property
