How to Add Scripts and Styles in WordPress?

To enqueue the script and styles we use two basic functions wp_enqueue_script() or wp_enqueue_style()

Adding Stylesheet in WordPress

Stylesheet are used to customize the look of your website. The enqueue function used to load Stylesheet is wp_enqueue_style(). Here is the basic syntax of the function:

wp_enqueue_style( $handle, $source, $dependencies, $ver, $media );

It takes 5 parameters among which first two parameters are compulsory and rests are optional. Here are the explanations of each parameter.

  • $handle is the name of the stylesheet to be loaded.
  • $source is the location of the stylesheet.
  • $dependencies refer to weather your style sheet has dependencies. If you set the dependencies then those dependencies are loaded first before your style sheet is loaded.
  • $version is the place where you can assign the version number.
  • $media defines the type of media where this style sheet will be loaded.


The default stylesheet for WordPress is style.css which is required in every WordPress theme. To enqueue the default style.css of your WordPress:

wp_enqueue_style( 'style', get_stylesheet_uri() );

Lets assume you want to load stylesheet with name my_style.css present in the ‘CSS’ folder in your root directory. Then the code looks like this.

wp_enqueue_style( 'my-custom-style', get_template_directory_uri() . '/css/my_style.css',false,'1.1','all');

The final and technically more correct way of adding styles is to first register the style using wp_register_style function and then use the enqueue function. wp_register_style has similar parameters as wp_enqueue_style function. Here is the full code that you can use in the functions.php file of your theme and plugin.

function my_assets(){
                wp_register_style('my-custom-style', get_template_directory_uri() . '/css/my_style.css', false,'1.1','all');
                wp_enqueue_style(' my-custom-style ');
add_action('admin_enqueue_scripts', ' my_assets');

Adding Scripts in WordPress

If you want to load any JavaScript files then you should use the wp_enqueue_script function. Here is the basic syntax of the function:

wp_enqueue_script( $handle, $source, $dependencies, $version, $in_footer);

Here is the explanation of the parameters.

  • $handle is the name of the script.
  • $source defines where the scripts are to be loaded.
  • $dependencies define the dependencies of the script if there is any.
  • $version defines the version number.
  • $in_footer takes two values true or false. True allows you to place the value in the footer and false allows you to place the script in the header.
