Adds a custom field to your post editing screens to add custom styles applied only on that page or post.
Attach custom styles to any page, post, or custom post type. Separate styles can be attached for print, screen, or mobile. You can also store your own library of frequently-used styles.
How to use the style library:
<ol>
<li>Add the styles you want on your settings page.</li>
<li>Navigate to an article which requires specific styles.</li>
<li>Select the library style from the drop down, leaving the style textarea blank.</li>
<li>Update or post the new document.</li>
</ol>
A newly-selected style from the style library will always overwrite any previous hand-written styles. If you wish to alter the library styles for a specific page, you can do this in the textarea after you’ve saved the page with the style library template.
By default, editing your saved stylesheets will have no impact on previously saved post-specific styles; set the option to pull styles from the library to change this.
Note: custom styles will not be included on archive pages; only on single post/Page views.
The use you’ll get out of this plugin depends on the flexibility of the theme you’re using and your own knowledge of CSS (Cascading Style Sheets).

WP Post Styling

Define custom styles for any post, page, or custom post type. Example: journal-style publications which want to create a unique design for articles.

<h3>What you need, where you need it – and when.</h3>
For WordPress 3.8 to 4.9+ – Backward compatibile to WordPress 3.5 (see <a href="https://wordpress.org/extend/plugins/admin-menus-fixed/other_notes/" rel="ugc">Other Notes</a>) 
Works with: <a href="https://wordpress.org/extend/plugins/ozh-admin-drop-down-menu/" rel="ugc">Ozh’ Admin Drop Down Menu 3.6+</a> and <a href="https://wordpress.org/extend/plugins/ag-custom-admin/" rel="ugc">AG Custom Admin 1.2.5+</a>
Admin Menus Fixed Three Ways: As a companion to Ozh’ Admin Drop Down Menu AND/OR AG Custom Admin OR Standalone (WordPress 3.5-3.7)
<ul>
<li>
New in v1.4 Now Responsive down to phone sizes. Ozh’ Admin Drop Down Menu header background automatically changes to high contrast when displayed on smaller screens.
</li>
<li>
New in v1.4 Ozh’ Admin Drop Down Menu Header Gradient now wraps when the header does; improving the look and readability!
</li>
<li>
Consolidates the WordPress Toolbar and Ozh’s menu and makes them both always readily available at the top of your window; no matter where you happen to be scrolled on a long page.
</li>
<li>
Incorporates HoverIntent to chill the Toolbar drop-down menu hair trigger, so now you can overshoot Ozh’ Menu without the Toolbar menu falsely stepping on it; causing you to move away until it closes, so that you can get to what you were going for. Way easier to work this way. Fast. Efficient.
</li>
<li>
Automatically adjusts to the WordPress Toolbar display state; whether disabled by Ozh’ Admin Drop Down Menu or AG Custom Admin.
</li>
</ul>
Standalone: (Depreciated) The WordPress Devs have taken a page from this plugin’s book, pulling the concept into core by fixed-positioning the Toolbar and Admin Menus in versions 3.8+, so the plugin code is shrinking. Kinda goes against the new direction of pulling code out of core and having plugins handle the function if you want/need it, but I’m glad that the concept has been adopted; because it was long overdue. The plugin is returning to its own core purpose, that of enhancing Ozh’ Admin Drop Down Menu, and I’m OK with that. – see <a href="https://wordpress.org/extend/plugins/admin-menus-fixed/other_notes/" rel="ugc">Other Notes</a>

The WordPress Toolbar and standard Admin Menu along the left side are made fixed-position in both expanded and collapsed modes; eliminating a lot of scrolling.
