Customize the loading icon

Customize the loading icon

Note that it changes the main loading icon, but not the small loading icon (composer, search menu, etc).

Edit your current theme or create a new theme component.

Go in </head> and paste this code:

<script type="text/x-handlebars" data-template-name="components/conditional-loading-spinner">
{{#if condition}}
<div class="custom-loader-container">

  <div class="my-custom-loader">
  </div>

</div>
{{else}}
  {{yield}}
{{/if}}
</script>

Replace or fill .my-custom-loader with your loader HTML code.

Go in CSS and paste this code:

.custom-loader-container {
    position: relative;
    margin: 20px 0 20px;
    display: flex;
    justify-content: center;
}

Add your custom loader CSS.

I really, really love this. Because we have a large number of categories, our category list page takes a few seconds to load. The unicycle makes me smile!

Hi @Canapin,
Thank you for sharing us, I really like it.
Is that possible to change the loader globally?

Thank you!

Canapin · October 25, 2020, 10:22am

If you’re talking about the small spinner, maybe start from this:

Don · October 25, 2020, 11:19am

Thank you @Canapin ,

I got it! I just target the spinner class and changed it to the pulser loader.

Johnny_McIvor · June 16, 2021, 3:14am

how do i replace it with a gif. for example:

Heather_Dudley · June 16, 2021, 2:10pm

Not currently possible.

Johnny_McIvor · June 16, 2021, 6:12pm

Can I replace it with a static image? I probably won’t change it though
