Modular Custom CSS

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. A declining trend compresses what a buyer would pay.

   Thanks for this! It seems Modular Custom CSS is the most modern plugin that takes advantage of WP 4.7+ features.

   I have never bothered to review any plugin before, but I frickin love this one, Im not a css expert so its normally a big hassle for me to make changes. I love the way you can use this in the customizer, live preview so you can see the changes straight away, Thanks so much for this, saving me so much time.

   Very good idea if you have to manage same CSS for different themes.

   Just tested this on a premium theme that I didn’t want to make a child theme for and it’s REALLY handy. The style changes in the Customizer are instantaneous. Also really well thought-out to have the theme-agnostic styles separated out from theme-specific. Thanks for the contribution!
