<p><strong>Head & Footer Code</strong> plugin helps you add custom code snippets (JavaScript, CSS, or HTML) to the page even if you are not a programmer. It could be within the <code><head></code> (site verification code for various services, custom styles, meta or Webfont link), right after opening <code><body></code> (pixel tracking, analytics or heatmap code) or just before closing <code></body></code> tag.</p>
<p>Go to <strong>Tools</strong> → <strong>Head & Footer Code</strong> in WordPress Dashboard. Insert custom code to HEAD, BODY or FOOTER section (depending on what you have to do).</p>
<p>All magic is done by hooking to WordPress hooks <code>wp_head</code>, <code>wp_footer</code> and <code>wp_body_open</code>.</p>

<h3>Homepage in Blog Posts mode</h3>
<p>If your WordPress shows the latest blog posts on the homepage, you can also add specific code only for the homepage on <strong>Tools</strong> → <strong>Head & Footer Code</strong> (there will be section <strong>Head, body and footer code on Homepage in Blog Posts mode</strong>)</p>
<h3>Article specific code</h3>
<p>To insert custom code specific for individual article (post, page or custom post type), use article-specific Metabox while editing post/page/custom post type (check out <a href="https://wordpress.org/plugins/head-footer-code/#screenshots" rel="ugc">Screenshots</a>). There choose if that specific code appends to site-wide code defined on <strong>Tools</strong> → <strong>Head & Footer Code</strong>, or to replace it.</p>
<h3>Category specific code</h3>
<p>You can also define a Category specific code on each individual category.</p>
<p>Other taxonomies (tag and custom taxonomy) do not have available their specific code, but for them a Global code is used instead.</p>

Head & Footer Code

This plugin is what exactly I'm looking for to add custom javascript and CSS codes to specific pages without inserting them inside the template.

A must have plugin

Easy add site-wide, category and article specific custom code before the closing </head> and </body>, or after opening <body> tag.
