Would like to create a progress indicator div using CSS animations? Check out the JSBin link provided. The desired behavior is to have the div width increase from 30% to 100% when the user clicks on stage3 after stage1, rather than starting from 0%. Although setting the initial width as 30% would achieve this, it may not be practical for multiple stages. The goal is for the animation to start from the final width of the last stage and then transition to the new stage's specified width.
document.getElementById('stage1').addEventListener('click', function() {
document.getElementById('progress').classList.add('stage1');
}, false);
document.getElementById('stage2').addEventListener('click', function() {
document.getElementById('progress').classList.add('stage2');
}, false);
document.getElementById('stage3').addEventListener('click', function() {
document.getElementById('progress').classList.add('stage3');
}, false);.progress-wrapper {
height: 10px;
width: 400px;
background-color: #BBDEFB;
}
#progress {
background-color: #AADE00;
height: 10px;
width: 0;
}
.stage1 {
animation-name: stage1;
animation-duration: 1s;
animation-fill-mode: forwards;
}
@keyframes stage1 {
to {
width: 30%;
}
}
.stage2 {
animation-name: stage2;
animation-duration: 1s;
animation-fill-mode: forwards;
}
@keyframes stage2 {
to {
width: 70%;
}
}
.stage3 {
animation-name: stage3;
animation-duration: 1s;
animation-fill-mode: forwards;
}
@keyframes stage3 {
to {
width: 100%;
}
