Can you share the two lines of CSS that would make something like this work? <div style="width: 200px" class="kawaii-backpack kawaii-happy"></div> or this: <div style="width: 200px"> <img src="kawaii-backpack.sgv" /> <img src="kawaii-happy.svg" /> </div> Edit: it should also work with a color user defined color.
