SVG Icons + Framework7
<p>Framework7 uses SVG icons in their example layouts like <a href="http://framework7.io/examples/tab-bar/" rel="nofollow">here</a>.</p>

<p>Here's their code for the first icon:</p>

<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>i.tabbar-demo-icon-1 {
  width: 30px;
  height: 30px;
  background-image: url("data:image/svg+xml;charset=utf-8,&lt;svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 30 30' fill='%23929292'&gt;&lt;g&gt;&lt;circle cx='15.2' cy='8.8' r='1.5'/&gt;&lt;polygon points='16.7,12.3 16.7,11.7 16.7,11.3 13.7,11.3 13.7,12.3 14.7,12.3 14.7,20.3 13.7,20.3 13.7,21.3 17.7,21.3 17.7,20.3 16.7,20.3'/&gt;&lt;path d='M15.2,2.3C8.3,2.3,2.7,7.9,2.7,14.8s5.6,12.5,12.5,12.5c6.9,0,12.5-5.6,12.5-12.5S22.1,2.3,15.2,2.3z M15.2,26.3 c-6.3,0-11.5-5.2-11.5-11.5S8.8,3.3,15.2,3.3s11.5,5.2,11.5,11.5S21.5,26.3,15.2,26.3z'/&gt;&lt;/g&gt;&lt;/svg&gt;");
}
.active i.tabbar-demo-icon-1 {
  background-image: url("data:image/svg+xml;charset=utf-8,&lt;svg xmlns='http://www.w3.org/2000/svg' x='0px' y='0px' viewBox='0 0 30 30' fill='%23007aff'&gt;&lt;path d='M15,2.6C8.1,2.6,2.5,8.2,2.5,15.1C2.5,22,8.1,27.6,15,27.6S27.5,22,27.5,15.1C27.5,8.2,21.9,2.6,15,2.6z M15,7.6 c0.8,0,1.5,0.7,1.5,1.5c0,0.8-0.7,1.5-1.5,1.5c-0.8,0-1.5-0.7-1.5-1.5C13.5,8.3,14.2,7.6,15,7.6z M17.5,21.6h-4v-1h1v-8h-1v-1h3V12 v0.6v8h1V21.6z'/&gt;&lt;/svg&gt;");
}</code></pre>
</div>

<p>Where did they get this background image URLs for the icons? How can I find links for others icons so I can replace the existing one?</p>
