Hello @chengjianping,
would you describe in more detail what you mean by “it was not synchronized to the css settings”? It would be useful to formulate the issue in this format: “I did [this], I was expecting [this], instead the plugin did [this]”. Feel free to use screenshots, if necessary.
On the linked website the caching is performed by the WP Rocket plugin. If by “it was not synchronized” you mean that the changes to the custom CSS code don’t show up on the frontend, then you might want to consider purging the WP Rocket caches after updating the CSS custom code.
I added css to your plug-in. I wanted to synchronize it to the css on the theme, but it was not automatically synced to the css of the theme. I also cleared the cache and it didn’t work.
To “synchronize the CSS” is not a technical term and it doesn’t describe the issue. Please describe in more detail what you did and what you want to achieve. Use screenshots.
I want to synchronize the css content added by your plug-in https://imgur.com/a/rEwiqgx directly to the theme’s css https://imgur.com/a/yRGc5m0. How can I synchronize it directly?
Any of the CSS codes added with the “Simple Custom CSS & JS” plugin will automatically be applied on the frontend. The CSS code added with the “WP Admin -> Appearance -> Customize -> Additional CSS” setting will also automatically be applied on the frontend.
These are two different systems to add CSS code to your website and they don’t need to be synchronized. In fact, if you add the same CSS code once with the “Simple Custom CSS & JS” plugin and a second time with “WP Admin -> Appearance -> Customize -> Additional CSS” setting, then the code will show up twice on the frontend. May I ask why do you want the same CSS code added twice to the website, once with the plugin and another time through the customizer?
