<p><strong>Script Surgery</strong> gives you a visual, actionable view of every script and style loaded on your WordPress site — broken down by page type (homepage, single post, product, cart, etc.).</p>
<h4>What it does</h4>
<p><strong>Visual asset inventory</strong><br />
See every enqueued script and style on each page type: the handle, which plugin or theme added it, file size, whether it loads in <code><head></code> (render-blocking) or footer, and async/defer status.</p>
<p><strong>Source attribution</strong><br />
Each asset is attributed to: WordPress Core, a plugin (by name), your theme, or an external CDN. No guesswork.</p>
<p><strong>Per-page-type disable rules</strong><br />
Disable any script or style on specific page types with one click. Elementor scripts loading on your checkout page? Slider scripts loading on cart? Disable them — no code required.</p>
<p><strong>Render-blocking detection</strong><br />
Scripts loading in <code><head></code> without async or defer are flagged as render-blocking. Styles are flagged similarly. Fix the highest-impact issues first.</p>
<p><strong>Bulk actions</strong><br />
“Only on this page” — disable a script everywhere except the current page type in one click. Reset individual or all rules at once.</p>
<h4>How data is collected</h4>
<p>Data is captured automatically when a logged-in administrator visits any frontend page. No cron jobs, no external requests. The WordPress admin bar shows a ⚗ indicator on each page type so you know what’s been captured.</p>
<h4>Privacy</h4>
<p>Script Surgery only runs for logged-in administrators. No data is sent externally. All data is stored in your own database (transients + one options entry).</p>

<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>
