<p>An essential WordPress plugin to easily insert scripts and styles (like Google Analytics, CSS, etc.) into your website’s header and footer.</p>
<p>Looking for a way to add Google Analytics, Facebook Pixel, or custom tracking code to your website’s header or footer?</p>
<p>Header and Footer Scripts is a simple yet powerful plugin that lets you inject code—such as Google Analytics, custom CSS, Facebook Pixel, and chat widgets—directly into your site’s header (<code><head></code>) or footer.</p>
<p>No bloat, no ads. This lightweight plugin simply does what it says: inserts code into your header and footer efficiently.</p>
<p>All you have to do is add the appropriate HTML code.</p>
<p>Don’t forget to wrap your code with proper tags.</p>
<pre><code><script type="text/javascript">
YOUR JS CODE HERE
</script>
</code></pre>
<p>Or for CSS:</p>
<pre><code><style type="text/css">
YOUR CSS CODE HERE
</style>
</code></pre>
<h4>Why use this plugin:</h4>
<ul>
<li>Insert scripts globally into the header and footer of your entire website.</li>
<li>Supports all script types including HTML, JavaScript, and CSS.</li>
<li>Add specific scripts to the header of individual posts or pages.</li>
<li>To insert code to Custom Post Type [New Feature].</li>
</ul>
<p>The plugin should be compatible with WooCommerce.</p>
<h4>What it does not offer</h4>
<ul>
<li>You can’t insert/execute PHP codes.</li>
</ul>
<p>Almost all WordPress themes support this “Header and Footer Scripts” plugin. If the codes are not appearing in your site [ask for support] or look at your theme file if they have standard <code>wp_head</code> and <code>wp_footer</code> hooks.</p>
