// Enqueue the stylesheet
function my_plugin_enqueue_styles() {
wp_enqueue_style( 'my-plugin-style', plugins_url( '/css/my-plugin-style.css', __FILE__ ), array(), '1.0.0' );
}
add_action( 'wp_enqueue_scripts', 'my_plugin_enqueue_styles' );
In this example, we are using the plugins_url() function to generate the URL of the stylesheet in the plugin directory. You can replace /css/my-plugin-style.css with the path to your own stylesheet.
Enqueuing Scripts
Enqueuing scripts follows a similar process as enqueuing styles. The main difference is that you will use the wp_enqueue_script() function instead.
Here is an example of how to enqueue a script in your WordPress plugin:
// Enqueue the script
function my_plugin_enqueue_scripts() {
wp_enqueue_script( 'my-plugin-script', plugins_url( '/js/my-plugin-script.js', __FILE__ ), array( 'jquery' ), '1.0.0', true );
}
add_action( 'wp_enqueue_scripts', 'my_plugin_enqueue_scripts' );
In this example, we are enqueuing a script called my-plugin-script.js located in the /js directory of our plugin. We are also specifying that the script depends on jQuery, which means that jQuery will be loaded before our script.
By enqueuing styles and scripts in your WordPress plugin, you ensure that they are loaded in the correct order and only on the pages where they are needed. This helps prevent conflicts with other styles and scripts and improves the overall performance of your plugin.
Remember to properly enqueue the styles and scripts in the main plugin file or a separate file that is included in the main plugin file using the appropriate WordPress hooks and actions.
