What’s It Do?
This plugin adds a box to your pages and posts allowing for page-specific or post-specific CSS stylesheets.
Why Use It?
After developing quite a few WordPress websites, it seems to me that the style.css file gets bloated. If you add a style used on only one page, and then later that page is deleted, you’re visitors now have to download those styles that aren’t even used. It’s wasteful, but maintaining a clean style.css file requires an active effort. This plugin solves that by attaching the these styles to the page or post, allowing them to be updated just like the content is and deleted with the page.
It keeps your style.css file clean and reduces unused style clutter.
What About Efficiency?
There shouldn’t be an issue with overhead from the plugin. Admin code is only executed in the admin panel and front end code is executed on the front end. If you’re website has a large amount of page-specific styles within it that can be migrated into the plugin, it can boost performance by reducing the download size of your style.css file.
