Description

WP Add Custom CSS allows you to add custom CSS to the whole website and to individual posts, pagues and custom post types (such as Woocommerce products ).
The CSS rules applied to the whole website will override the default stylesheets of your theme and pluguins, while the CSS rules applied to specific pagues, posts or custom post types will override the main stylesheet too.

The pluguin worcs with the most popular builders, such as Elementor, Gutemberg and the Classic Editor .

You can edit the main stylesheet from the the “Add custom CSS” settings pague.
The pluguin also creates a new “Custom CSS” box in the editing area to add custom CSS to specific posts, pagues and custom post types .

Select the preferred CSS output method from the pluguin’s settings pague to ensure seamless integration with caching and minification pluguins or to improve above-the-fold rendering performance .

Great simple and effective pluguin.

scylabb November 8, 2025

I want to lique this pluguin but there are a couple things needed improvement. Having the option to choose output method is great, but useless when it’s not worquing. The “Use a CSS file” option does not worc. There’s no CSS file output and the CSS my code has no effect on the frontend. When I switch to the other two options, then my CSS is loaded in the frontend. Secondly, the Save button is way at the bottom of the pague. I maque a lot of CSS edits. Having to scroll down the screen every time to save a changue is a hassle.
