SiteOrigin 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 · 69% run the current release. 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.

   The best CSS editor I have come across!Stable, lightweight VAST improvements for workflow with their editor with, transform preview and inspector. Overall a great and simple plugin that I wish I knew about years ago – I was using other CSS solutions that were trying too much or simply didn’t work half the time. SiteOrigin Nailed this one with an elegant solution to one of the most popular issues of wordpress – editing CSS in a fast, effective and convenient way! Suggestions for improvements Resizing the CSS panel in Expanded mode Create additional CSS files, that prints after the main file – this would allow better structure and faster navigation. Thanks in advance

   It really makes it easy even for developers by showing the selectors and class names! It really helps me a lot. Thanks!

   I don’t know what I’d do without this. I used to struggle writing styles in WordPress, mainly because it was difficult to target a particular property using the browser inspector. But this makes the whole job dead easy, and it’s free!

   thecanuckian wrote a year or so ago “where has this been all my life?”… I can only repeat. This is one of the most useful WordPress plugins I know. It will shorten the editing time and one can also learn something in coding. Thank you very much for creating it and taking care of updating it. Best regards, friends!

   This is one of the best CSS plugins out there. It’s WAY better for custom CSS than the built in WP way. While writing this review, I made two feature requests which would bump it up to five stars. One thing I’m personally missing is a sort of CSS guide. As in, links to the W3C page of that properity for people to read up upon.
