Description
@keyframes
to change the color of a button in its hover state.
Here's an example of changing the width of an image on hover:
<style>
img:hover {
animation-name: width;
animation-duration: 500ms;
}
@keyframes width {
100% {
width: 40px;
}
}
</style>
<img src="https://bit.ly/smallgooglelogo" alt="Google's Logo" />
Instructions
ms
stands for milliseconds, where 1000ms is equal to 1s.
Use CSS @keyframes
to change the background-color
of the button
element so it becomes #4791d0
when a user hovers over it. The @keyframes
rule should only have an entry for 100%
.
Tests
tests:
- text: The @keyframes rule should use the <code>animation-name</code> background-color.
testString: assert(code.match(/@keyframes\s+?background-color\s*?{/g), 'The @keyframes rule should use the <code>animation-name</code> background-color.');
- text: There should be one rule under <code>@keyframes</code> that changes the <code>background-color</code> to <code>#4791d0</code> at 100%.
testString: assert(code.match(/100%\s*?{\s*?background-color:\s*?#4791d0;\s*?}/gi), 'There should be one rule under <code>@keyframes</code> that changes the <code>background-color</code> to <code>#4791d0</code> at 100%.');
