ローディングアイコンをカスタマイズする

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!

Don · 2020 年 10 月 23 日午前 9:52

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

Thank you!

Canapin · 2020 年 10 月 25 日午前 10:22

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

Don · 2020 年 10 月 25 日午前 11:19

Thank you @Canapin ,

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

Johnny_McIvor · 2021 年 6 月 16 日午前 3:14

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

Heather_Dudley · 2021 年 6 月 16 日午後 2:10

Not currently possible.

Johnny_McIvor · 2021 年 6 月 16 日午後 6:12

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