How to Register Conditional Stylesheets in WordPress

Are you looking for a way to register conditional stylesheets? While there’s probably a plugin for this, we have created a quick code snippet that you can use to register conditional stylesheet in WordPress.

The first parameter should be the condition, with the rest being identical to those used in wp_register_style.

Example:

        register_style_conditional( 'lt IE 9', 'ubuntu-regular', 'http://fonts.googleapis.com/css?family=Ubuntu:400' );
        wp_enqueue_style( 'ubuntu-regular' );

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

/**
 * Registers a style, as with wp_register_style, between a condition (e.g. 'lt IE 9')
 * @param  string $condition Condition under which to load the style
 * @param  string $handle Name of the stylesheet
 * @param  string|bool $src Path to the stylesheet root
 * @param  array $deps Array of handles of stylesheets that this one depends upon
 * @param  boolean $ver Stylesheet version number
 * @param  string $media Media for which this stylesheet has been defined
 */
function register_style_conditional( $condition, $handle, $src, $deps = array(), $ver = false, $media = 'all' ) {
    wp_register_style( $handle, $src, $deps, $ver, $media );

    global $wp_styles;
    $wp_styles->add_data( $handle, 'conditional', $condition );
}
