CSS Question

load progress bar smoothly and within certain time

Hi I have a multi group progress bar that loads from left to right smoothly but it takes around 5 secs to load.

How can i update it to load smoothly from left to right and in 3 secs?

The group bar could have 6 or more groups and should load in 3 secs

Here the link to working code


<h1 class="u-pb--lg text-bold">Grouped ProgressBar Component Examples</h1>
<div class="space">
<div> Example: User earning all the points</div>
<div class="well-ProgressGroup">
<!-- react-text: 94 -->
<!-- /react-text -->
<div class="well-background--concept1 well-ProgressGroup--progress" style="width: 50%; animation-delay: 1s; z-index: -1; height: 50px;"></div>
<div class="well-background--concept2 well-ProgressGroup--progress" style="width: 75%; animation-delay: 2s; z-index: -2; height: 50px;"></div>
<div class="well-background--concept3 well-ProgressGroup--progress" style="width: 100%; animation-delay: 3s; z-index: -3; height: 50px;"></div>
<div class="well-background--concept4 well-ProgressGroup--progress" style="width: 250%; animation-delay: 4s; z-index: -4; height: 50px;"></div>
<div class="well-background--concept5 well-ProgressGroup--progress" style="width: 300%; animation-delay: 5s; z-index: -5; height: 50px;"></div>

.well-ProgressGroup {
display: flex;
background: #d3d4d5;
flex-direction: row;
border-radius: 0.5em;
overflow: auto;
position: relative;
z-index: 1;

@keyframes loadbar {
0% {
opacity: 1;
100% {
transform: translateX(0);
opacity: 1;

.well-ProgressGroup--progress {
transform: translateX(-100%);
animation: loadbar 1s linear forwards;
/* -webkit-animation: loadbar 1s forwards; */
opacity: 0;
background: blue;

.well-ProgressGroup--progress:not(:last-child) {
border-right: 1px solid white;

.well-background--concept1 {
background: tomato;

.well-background--concept2 {
background: blue;

.well-background--concept3 {
background: purple;

.well-background--concept4 {
background: red;

.well-background--concept5 {
background: green;

Answer Source

Each of your .well-ProgressGroup--progress divs has an animation delay inline style in the HTML, update these in increments of 3s / 5 = 0.6s so 0, 0.6s, 1.2s, 1.8s, 2.4s. Then in your CSS adjust the animation: loadbar 1s linear forwards; within .well-ProgressGroup--progress to animation: loadbar 0.6s linear forwards;

The first change is so that your bars fill one after the other with no gaps. The second is the speed at which each bar fills. See here
