Creating an Indefinite Animated Loading Bar in Dash (Python Dashboard Tutorial)
In this video, you'll learn how to build a custom animated loading bar using Dash and Bootstrap, perfect for web dashboards or internal tools where you want to show ongoing activity without relying on a spinner.
Python File : https://www.kaggle.com/code/krpurba/d...
CSS Here :
---------------------------------
/* indefinite progress bar */
.loadingbar{
position:fixed;
width:100vw;
height:31px;
top:0px;
left:0px;
z-index:1000;
overflow-x: hidden;
}
.loadingbar .line{
position:absolute;
opacity: 0.4;
background:#75a7ff;
width:150%;
height:3px;
}
.loadingbar .subline{
position:absolute;
background:#75a7ff;
height:3px;
}
.inc{
animation: increase 2s infinite;
}
.dec{
animation: decrease 2s 0.5s infinite;
}
@keyframes increase {
from { left: -5%; width: 5%; }
to { left: 130%; width: 100%;}
}
@keyframes decrease {
from { left: -80%; width: 80%; }
to { left: 110%; width: 10%;}
}
/* end of indefinite progress bar */

🚀 What this video covers:
Creating a smooth, indefinite loading animation with custom HTML & CSS
Using Dash callbacks to control when the loading bar appears and disappears
Simulating data loading with a delay (`time.sleep`)
Updating content dynamically after loading completes
Working with `datetime.now()` to show live timestamps
Preparing CSS asset folder
💡 Unlike default dcc.Loading or dcc.Spinner, this example gives you full control over the look and timing of your loader — great for stylized dashboards!
