What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

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.

    Thanks for making this. JavaScript support, or similar plugin for JavaScript would be amazing! I know custom JS plugins exist, but they lack the simplicity.

    I searched a long time and this plugin is the best! It has a nice user interface and most important it shows CSS mistakes! I found with this Plugin why my CSS before was not working. This topic was modified 4 years ago by mayan62.

    Поменять стили настолько просто, что особо и добавить больше нечего. Особо полезен этот плагин для начинающих разработчиков.

    Absolutely love this; one note; sometimes after saving the changes and go back to change say one character or a line, it doesn’t popular “save changes”. Maybe a small bug? In either case, I use the plug-in for every WP site I run and can’t live without it. No more going through different theme menu’s just to edit the CSS!

    This is the kind of plugin you’d easily donate $10 for because it’s so useful. Much thanks to WASP Themes (creators of the Yellow Pencil plugin) for offering such a lightweight and useful tool for nothing. If you use custom css to regularly style elements like I do, there’s nothing quite like being able to preview those live changes in the window while you code. I’ve been using this for about 16 months, I use it on over 10 different wordpress installs to cleanly and effectively make simple color changes, add padding, etc.

    Does exactly what it says on the tin – and more. Excellent feature of being able to edit CSS and see results in realtime before saving. Fantastic time-saver – thanks to the devs!
