We want our products to leave a good impression on first-time users. So whenever we build something, we make it possible first, then ask if it can be a little unique. And the glowing loader is one of those attempts.

Here is the original version onjsfiddle (33 changes).

Create your own loader in HTML and CSS

The loader design has a container and 3 elements: the background button, glowing spinner, and the logo. While the button and the spinner are all overlay layers (use absolute positioning).

Let's start with a straigt forward HTML markup as following:

<divclass="logo-container"><spanclass="spinner"></span><spanclass="background"></span><imgclass="logo"src="yourlogo.svg"height="28"/></div>

1. The container

The main point of the container is to groups the elements together, and positioning its childrenlogo in the center. Let's useflex in this example.

.logo-container{/* align children in the center */display:flex;align-items:center;justify-content:center;position:relative;/* a circle with 60x60 pixels */width:60px;height:60px;border-radius:50%;}

Now we have a plain logo.

Before going into the button background and the spinner. We need to make sure they are overlay layers, by applying absolute positioning as following.

.background,.spinner{position:absolute;display:inline-block;height:100%;width:100%;}

2. The button background

The button background is a circle, with a matte-ish gradient and shadows. Here's one way to do it

/* The button background layer */.background{border-radius:50%;background-image:linear-gradient(0deg,#0f1013,#252730);box-shadow:04px4px-1pxrgba(0,0,0,0.6),04px6px1pxrgba(0,0,0,0.3),01px2px1pxrgba(0,0,0,0)inset,018px32px-2pxrgba(255,255,255,0.1)inset;}

It'll look like this now:

3. Bring logo to front

In case you can't see your logo, you will need to usez-index to bring thelogo on top. Simple as the following CSS:

.logo{z-index:2;}

4. Glowing spinner

Glowing spinner layer use atop-border attribute, with shadow to add the glowing effect. It can be done as following:

.spinner{border-radius:50%;border-top:2pxsolid#ae34db;/* glowing with shadow (30% of #ae34db) */box-shadow:0-5px5px#ae34db4d;/* add spin animation */animation:spin1slinearinfinite;}

Then add the animation keyframes. It's basically a keyframe that rotate the light spinner in a 360 degree circle

@keyframesspin{0%{transform:rotate(0deg);}100%{transform:rotate(360deg);}}

You should see a glowing spinner with your logo inside. Here is our final result.

You can play with thespin keyframe to change the glowing colors, or spread the shadow more to make it like a siren light.

Now you know how to create a glowing loader. It contains a matte-ish gradient background, with a glowing spinner. You can check out the final resulton jsfiddle;
