This plugin will enable a custom css manager on administration page to add Custom CSS code to your WordPress website. It will automatically override any theme or plugin default styles. It also very useful if you want to add customization to your website but do not want to edit your theme or plugin css files.
It comes with two ways to add the custom css code:
1. Setting
You can go to Appearance → Custom CSS, then you will see a big box/textarea. Put your css code there.
2. Customizer – Live Preview
If you want to see the live preview while you adding the custom css code, then you can go to Appearance → Customize, after that open the Custom CSS section tab.
Great, works nicely! Thank you! However, search is not working as suppose to, and doesn’t work at all in russian if you have russian comments. Work around is to go to Custom CSS. But that’s different story. Pleasure.
Fulfill your role magnanimously!
I was brought into a project after another developer. Usually I would configure my own stylesheet but this plugin was installed and I didn’t have to. Will keep this in mind for future projects.
Great alternative to Simple Custom CSS, now that it’s no longer being maintained. You would think there wasn’t much to say about a custom css plugin, but this one not only adds the usual Custom CSS pane to Appearance, but adds it to Customize as well, so you can preview your code changes without having to refresh and switch tabs. Love this feature!
Generally a well-thought-out plugin, with scroll bars and pane expanders where you need them, numbered lines, a link to Mozilla’s html/css tutorial (which, let’s be honest, is friendlier than W3’s), and keeps the promotion for their other products unobtrusive and out of the way of functionality.
The only suggestion I would make is to add an additional save button near the top of the custom css box on the Custom CSS pane, as well as the one at the bottom.
Doing one thing and doing it good.
