-
-	<p>If you want to insert an icon manually using the <code>:before</code> selector, you can setup CSS rules like the following example. <strong>Make sure to set the size to a multiple of 16px</strong> or the icons could end up looking fuzzy:</p>
-
-<p><textarea class="code" style="min-height: 150px;" onclick="select();">.my-icon:before {
-	content: '\f408';
-        display: inline-block;
-        -webkit-font-smoothing: antialiased;
-        font: normal 32px/1 'Genericons';
-        vertical-align: middle;
-}</textarea></p>
-
-	<p>Add a matching class to your HTML:</p>
-
-	<p><code>&lt;div class="my-icon"&gt;You're a Star!&lt;/div&gt;</code></p>
-
-	<p>Here's the result: <span class="my-icon">You're a Star!</span></p>
-
-	<h2>Examples</h2>
-
-	<p>Turn every icon a <span style="color: #fa8072;">Salmon</span> color:</p>
-
-<p><textarea class="code" style="min-height: 70px" onclick="select();">
-.genericon {
-	color: #fa8072;
-}</textarea></p>
-
-	<p>Or turn the stars <span style="color: #ffd700;">Gold</span>:</p>
-
-<p><textarea class="code" style="min-height: 70px" onclick="select();">
-.genericon-star {
-	color: #fa8072;
-}</textarea></p>
-
-	<p>Use icons for bulleted lists:</p>
-
-	<ul class="my-checklist">

-		<li>Two</li>
-		<li>Three</li>

-	<h2>CSS Preprocessors</h2>
-
-	<p>Preprocessing extensions such as Sass (SCSS Syntax) or LESS</a> can make it easier to manage CSS for a lot of things at once using things like variables and mixins.</p>
-
-	<p>This example will seup the basic genericon rules and sets a color you can use for all icons using Sass:</p>
-
-<p><textarea class="code" style="min-height: 360px;" onclick="select();">$icon-color: "#fa8072";
-
-.genericon {
-        color: $icon-color;

-	<h2>Fallback images for IE7 and below</h2>
-
-	<p>Genericons <strong>does not come with fallback icons by default</strong> -- therefore you have to create them yourself. If you are using HTML similar to this example:
-
-	<p><code>&lt;span class="genericon genericon-warning"&gt;&lt;/span&gt;</code></p>
-
-	<p>You can use the asterisk hack to serve a different icon to IE7 once you have saved the fallback icons to your project:</p>
-
-<textarea class="code" style="min-height: 85px;" onclick="select();">.genericon-warning {
-        *background: url(fallback-icon.png) no-repeat center center;
-        *text-indent: 100%;

-
-	<p>If you want to insert an icon manually using the <code>:before</code> selector, you can setup CSS rules like the following example. <strong>Make sure to set the size to a multiple of 16px</strong> or the icons could end up looking fuzzy:</p>
-
-<p><textarea class="code" style="min-height: 150px;" onclick="select();">.my-icon:before {
-	content: '\f408';
-        display: inline-block;
-        -webkit-font-smoothing: antialiased;
-        font: normal 32px/1 'Genericons';
-        vertical-align: middle;
-}</textarea></p>
-
-	<p>Add a matching class to your HTML:</p>
-
-	<p><code>&lt;div class="my-icon"&gt;You're a Star!&lt;/div&gt;</code></p>
-
-	<p>Here's the result: <span class="my-icon">You're a Star!</span></p>
-
-	<h2>Examples</h2>
-
-	<p>Turn every icon a <span style="color: #fa8072;">Salmon</span> color:</p>
-
-<p><textarea class="code" style="min-height: 70px" onclick="select();">
-.genericon {
-	color: #fa8072;
-}</textarea></p>
-
-	<p>Or turn the stars <span style="color: #ffd700;">Gold</span>:</p>
-
-<p><textarea class="code" style="min-height: 70px" onclick="select();">
-.genericon-star {
-	color: #fa8072;
-}</textarea></p>
-
-	<p>Use icons for bulleted lists:</p>
-

-		<li>Two</li>
-		<li>Three</li>

-	<h2>CSS Preprocessors</h2>
-
-	<p>Preprocessing extensions such as Sass (SCSS Syntax) or LESS</a> can make it easier to manage CSS for a lot of things at once using things like variables and mixins.</p>
-
-	<p>This example will seup the basic genericon rules and sets a color you can use for all icons using Sass:</p>
-
-<p><textarea class="code" style="min-height: 360px;" onclick="select();">$icon-color: "#fa8072";
-
-.genericon {
-        color: $icon-color;
-}
-
-@mixin genericon-rules {
-        display: inline-block;
-        -webkit-font-smoothing: antialiased;
-        font: normal 16px/1 'Genericons';
-        vertical-align: middle;
-}
-
-.my-icon:before {
-	content: '\f408';
-        @include genericon-rules;
-}</textarea></p>
-
-	<p>Here is a similar example for LESS:</p>
-
-<p><textarea class="code" style="min-height: 360px;" onclick="select();">@icon-color: "#fa8072";
-
-.genericon {
-        color: @icon-color;
-}
-
-.genericon-rules {
-        display: inline-block;
-        -webkit-font-smoothing: antialiased;
-        font: normal 16px/1 'Genericons';
-        vertical-align: middle;
-}
-
-.my-icon:before {
-	content: '\f408';
-        .genericon-rules;
-}</textarea></p>
-
-	<h2>Fallback images for IE7 and below</h2>
-
-	<p>Genericons <strong>does not come with fallback icons by default</strong> -- therefore you have to create them yourself. If you are using HTML similar to this example:
-
-	<p><code>&lt;span class="genericon genericon-warning"&gt;&lt;/span&gt;</code></p>
-
-	<p>You can use the asterisk hack to serve a different icon to IE7 once you have saved the fallback icons to your project:</p>
-
-<textarea class="code" style="min-height: 85px;" onclick="select();">.genericon-warning {
-        *background: url(fallback-icon.png) no-repeat center center;
-        *text-indent: 100%;
-}</textarea>
