Adding other css files to wp_head

Question

I am editing the standard twentythirteen theme that comes with the latest wordpress. I need to add a few of my own .css files into the wp_head but I'm not sure how to do this. I'm currently calling my files outside of wp_head but this is messy and would like to do it properly. ``` <?php wp_title( '|', true, 'right' ); ?> /bootstrap.css" /> ``` Where is it being defined what goes into wp_head and how do I add my own to it?

Accepted Answer

To add your own css in the wp_head(), you need to use a collection of WordPress functions:

First, you'll put this in your theme's functions.php file:

`add_action('wp_enqueue_scripts', 'your_function_name');`

(This uses the add action hook, hooking into the wp_enqueue_scripts action.)

Then, you'll need to add the function to your functions.php file that will utilize the WordPress function wp_enqueue_style:

```
function your_function_name() {
    wp_enqueue_style('my-script-slug',  get_stylesheet_directory_uri() . '/your_style.css');
}
```

Note the use of get_stylesheet_directory_uri() - this gets the proper stylesheet directory for your theme.

This is also the proper way to enqueue scripts into your header. Example:

```
function your_function_name() {
    // Enqueue the style
    wp_enqueue_style('my-script-slug',  get_stylesheet_directory_uri() . '/your_style.css');
    // Enqueue the script
    wp_enqueue_script('my-script-slug',  get_stylesheet_directory_uri() . '/your_script.js');
}
```

Which uses the WordPress wp_enqueue_script function.

Finally, it is worth mentioning that altering the twenty thirteen (or any other core theme) theme directly is usually discouraged. The recommendation is to create a child theme (overkill in my opinion, but worth mentioning).
