Head & Footer Code 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.
Go to Tools → Head & Footer Code in WordPress Dashboard. Insert custom code to HEAD, BODY or FOOTER section (depending on what you have to do).
All magic is done by hooking to WordPress hooks <code>wp_head</code>, <code>wp_footer</code> and <code>wp_body_open</code>.

<h3>Homepage in Blog Posts mode</h3>

<h3>Article specific code</h3>
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 Tools → Head & Footer Code, or to replace it.
<h3>Category specific code</h3>
You can also define a Category specific code on each individual category.
Other taxonomies (tag and custom taxonomy) do not have available their specific code, but for them a Global code is used instead.

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.

This plug-in takes the URL, chops it into pieces, and adds each “piece” as an additional 
class to the <code>body</code> tag.
Meaning, if your page’s URL is: 
http://www.example.com/2012/02/24/wordpress-plugin-add-url-slugs-as-body-classes/ 
Your page’s <code>body</code> tag would have at least these classes: 
 2012 02 24 wordpress-plugin-add-url-slugs-as-body-classess
It gets much stronger when you start thinking about Categories or nested Pages: 
 http://www.example.com/category/wordpress/ 
which would add: 
 category wordpress 
while: 
 http://www.example.com/movies/star-trek/wrath-of-khan/ 
would add: 
 movies star-trek wrath-of-khan
This allows you to very easily add custom CSS and/or JS to these pages based on these new CSS classes.
Please let me know if you have any questions/suggestions/thoughts,
