Found Interesting things when you click a link in dev.to you will see a colorful progress navbar grow width it's so cool.
I just inspect how dev.to implement it. let's show code i have found:
First defined html dom like this
<div class="navigation-progress showing" id="navigation-progress"></div>
Then use css *animate attributes
// defined background with linear-gradient
.navigation-progress {
position: fixed;
top: 0;
background: linear-gradient(to right, orange, yellow, green, cyan, blue, violet);
z-index: 102;
height: var(--su-1);
width: 0%;
}
// play animation when navigation-progress dom added showing class
.navigation-progress.showing {
display: block;
width: 140%;
-webkit-animation: grow-width 3200ms ease-out, pulsate 1.4s infinite ease-in-out;
animation: grow-width 3200ms ease-out, pulsate 1.4s infinite ease-in-out;
}
// define keyframes
@keyframes grow-width {
from {
width: 0;
}
to {
width: 100%;
}
}
These CSS defined animation grow-width will infinite play until page loaded.
Hope it can help you :) Demo
