Descripción

An essential WordPress plugin to easily insert scripts and styles (like Google Analytics, CSS, etc.) into your website’s header and footer.

Looking for a way to add Google Analytics, Facebook Pixel, or custom tracking code to your website’s header or footer?

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 (<head>) or footer.

No bloat, no ads. This lightweight plugin simply does what it says: inserts code into your header and footer efficiently.

All you have to do is add the appropriate HTML code.

No olvides envolver tu código con las etiquetas adecuadas.

<script type="text/javascript">
YOUR JS CODE HERE
</script>

O para CSS:

<style type="text/css">
YOUR CSS CODE HERE
</style>

Por qué usar este plugin:

Insert scripts globally into the header and footer of your entire website.
Supports all script types including HTML, JavaScript, and CSS.
Add specific scripts to the header of individual posts or pages.
Insertar código en tipos de contenido personalizado [nueva característica].

El plugin debería ser compatible con WooCommerce.

Lo que no ofrece

No puedes insertar o ejecutar códigos PHP.

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 wp_head and wp_footer hooks.

One of the most useful plugins. I was looking for a plugin that allows adding Metadata. Then I founs this, and it is very useful. Thanks a lot for your efforts guys. P.S. Thank you for the last update. It corrects some errors.

I’ve recently switched themes, and my previous theme allowed me to add custom CSS directly from the page editor. Unfortunately, my new theme lacks this feature. This plugin appears to be the only one that restores that functionality, enabling me to inject CSS specifically for individual pages. While other plugins offer global injection, which is certainly useful, I find that for unique pages like the homepage or special types, it’s essential to have the ability to add targeted styles without affecting the rest of the site. This plugin is a great solution for that!P.S. No bacon was saved during or after this message. Nom nom nom. lol.

Very useful plugin

I like that the plugin is up to the point and does what it is supposed to do. However, I believe it vulnerable to hijacks and injections. Since I’ve started using the plugin, some ads appear in new tab once I click on a link to the website. So I uninstalled the plugin and now will look for another solution.
