In our previous blog post, we updated our progress bar code to use React and create a reusable progress bar component. In this tutorial, we’ll take it a step further and show you how to add animations to our progress bar using CSS and React.
Adding Animations with CSS
First, let’s update our CSS to add animations to our progress bar. Open up your ProgressBar.css
file and add the following code:
.progress-bar {
width: 100%;
height: 20px;
background-color: #ddd;
border-radius: 10px;
position: relative;
}
.progress {
height: 100%;
background-color: #4CAF50;
border-radius: 10px;
position: absolute;
top: 0;
left: 0;
animation-name: progress-animation;
animation-duration: 2s;
animation-timing-function: ease-out;
}
@keyframes progress-animation {
from {
width: 0%;
}
to {
width: 100%;
}
}
In this code, we’ve added a position: relative
to the progress-bar
element and a position: absolute
to the progress
element. This will allow us to position the progress
element inside the progress-bar
element and animate its width without affecting the layout of other elements.
We’ve also added a CSS animation to the progress
element called progress-animation
. The animation starts with a width of 0%
and ends with a width of 100%
. It lasts for 2s
and has an easing effect.
Updating the Progress Bar Component
Now that we have our CSS animations set up, let’s update our ProgressBar
component to use them. Open up ProgressBar.js
and update the progress
element to include a className
of animate
.
<div className="progress animate" style={{ width: `${progress}%` }}></div>
In addition to the progress
class, we’ve added a new animate
class to trigger the CSS animation.
Conclusion
By adding animations to our progress bar using CSS and React, we can create a more engaging user experience and draw attention to the progress. Of course, you can customize the design and animation of the progress bar to match your website’s style.
