FAQ

Will this Plugin work on my WordPress.com website?

Sorry, this plugin is available for use only on self-hosted (WordPress.org) websites.

My Custom CSS isn’t showing up

There are several reasons this could be happening:

  • Your CSS is targeting the wrong selector.

  • Your CSS selectors aren’t specific enough.

For instance, you may have:

a {
    color: #f00;
}

When you need:

\#content a {
    color: #f00;
}

The specificity you need depends upon the CSS rules you are attempting to override.

  • Your CSS isn’t valid.

Please check your CSS at the W3C CSS Validation Service.

Indispensable. I can add custom css from the WP root admin panel. But memo to the developers: you mark mediaqueries with red x's. This doesn't affect performance, but please, it's long past time to fix this.

Instead of using print_scripts() to insert the CSS directly into the HEAD, CSS styles are generated within simple-custom-css.php, then added via wp_enqueue_scripts, so now it will appear in the HEAD as:

    <link rel="stylesheet" href="http://yoursite.com/?sccss=1" />

…even though no css file is actually generated. Please see the comments within the Plugin file for more detailed information.
