Ion-spinner as background image

Hey is there anyway to use the ion-spinner svgs as a background image for an element? For instance I’d like to use it as a preloader for an image.


I’m wondering if this is the right thing to do if you have a lot of images. I have an app that loads photos in a collection-repeat directive to minimize the number of DOM objects in my webview. But I noticed that the ion-spinner directive expands dramatically after compile.

compare ionicons CSS animation:

<i class="icon ion-load-c ion-spin light">:before</i>
// Animation Icons
// --------------------------

.ion-spin {
  -webkit-animation: spin 1s infinite linear;
  -moz-animation: spin 1s infinite linear;
  -o-animation: spin 1s infinite linear;
  animation: spin 1s infinite linear;

@-moz-keyframes spin {
  0% { -moz-transform: rotate(0deg); }
  100% { -moz-transform: rotate(359deg); }
@-webkit-keyframes spin {
  0% { -webkit-transform: rotate(0deg); }
  100% { -webkit-transform: rotate(359deg); }
@-o-keyframes spin {
  0% { -o-transform: rotate(0deg); }
  100% { -o-transform: rotate(359deg); }
@-ms-keyframes spin {
  0% { -ms-transform: rotate(0deg); }
  100% { -ms-transform: rotate(359deg); }
@keyframes spin {
  0% { transform: rotate(0deg); }
  100% { transform: rotate(359deg); }

with ion-spinner

<ion-spinner class="spinner-light spinner spinner-lines" icon="lines"><svg viewBox="0 0 64 64"><g stroke-width="7" stroke-linecap="round"><line x1="10" x2="10" y1="17.0079" y2="46.9921"><animate attributeName="y1" dur="750ms" values="16;18;28;18;16;16" repeatCount="indefinite"></animate><animate attributeName="y2" dur="750ms" values="48;46;36;44;48;48" repeatCount="indefinite"></animate><animate attributeName="stroke-opacity" dur="750ms" values="1;.4;.5;.8;1;1" repeatCount="indefinite"></animate></line><line x1="24" x2="24" y1="16" y2="48"><animate attributeName="y1" dur="750ms" values="16;16;18;28;18;16" repeatCount="indefinite"></animate><animate attributeName="y2" dur="750ms" values="48;48;46;36;44;48" repeatCount="indefinite"></animate><animate attributeName="stroke-opacity" dur="750ms" values="1;1;.4;.5;.8;1" repeatCount="indefinite"></animate></line><line x1="38" x2="38" y1="16.9921" y2="46.0158"><animate attributeName="y1" dur="750ms" values="18;16;16;18;28;18" repeatCount="indefinite"></animate><animate attributeName="y2" dur="750ms" values="44;48;48;46;36;44" repeatCount="indefinite"></animate><animate attributeName="stroke-opacity" dur="750ms" values=".8;1;1;.4;.5;.8" repeatCount="indefinite"></animate></line><line x1="52" x2="52" y1="22.9606" y2="40.0315"><animate attributeName="y1" dur="750ms" values="28;18;16;16;18;28" repeatCount="indefinite"></animate><animate attributeName="y2" dur="750ms" values="36;44;48;48;46;36" repeatCount="indefinite"></animate><animate attributeName="stroke-opacity" dur="750ms" values=".5;.8;1;1;.4;.5" repeatCount="indefinite"></animate></line></g></svg></ion-spinner>

I have not tested, but will the added overhead in the DOM tree for 20+ rendered items in collection-repeat be too much?

Thoughts anyone?
