<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>

<p>Other taxonomies (tag and custom taxonomy) do not have available their specific code, but for them a Global code is used instead.</p>
