This is an SVG sprite container with a single SVG icon inside.
<svg style="display: none">
    <symbol id="icon-angle-down"
            viewBox="0 0 24 24">
        <path d="M7.41 8.59L12 13.17l4.59-4.58L18 10l-6 6-6-6 1.41-1.41z"/>
        <path fill="none" d="M0 0h24v24H0V0z"/>

<h1>An SVG Icon</h1>

<p>This is a demonstration of having the same SVG icon but in one instance it is unoptimized and in the other it is run through <a href="">SVGOMG</a>. The third instance is a reference to an SVG inside an inline sprite.</p>

<p>Look at the HTML editor above to see the underlying code.</p>

<h2>The unoptimized SVG</h2>

<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 21.1.0, SVG Export Plug-In . SVG Version: 6.00 Build 0)  -->
<svg version="1.1" id="Layer_1" xmlns="" xmlns:xlink="" x="0px" y="0px" width="24px" height="24px" viewBox="0 0 24 24" enable-background="new 0 0 24 24" xml:space="preserve" class="svg-icon">
    <path d="M7.41,8.59L12,13.17l4.59-4.58L18,10l-6,6l-6-6L7.41,8.59z"/>
    <path fill="none" d="M0,0h24v24H0V0z"/>

<h2>The minified and optimized SVG</h2>

<svg class="svg-icon" viewBox="0 0 24 24"><path d="M7.41 8.59L12 13.17l4.59-4.58L18 10l-6 6-6-6 1.41-1.41z"/><path fill="none" d="M0 0h24v24H0V0z"/></svg>

<h2>Referencing the SVG from a sprite</h2>
