This simple plugin hooks to the wp_enqueue_scripts and removed the id='<handle of the css file>-css' attribute. Most of the time you don’t need these IDs anyway.

I am using the mod_pagespeed module on my server and the combine_css filter doesn’t work if the <link> tags have ID attributes. So based on this blog post I created a very very simple (basically one-liner) plugin that removes the ID attribute using regex.

There is also a very simple unit test for it, created using wp-cli: wp scaffod plugin ....

Enjoy the speedy sites! 🙂
