Adding the following in child theme’s functions.php
will load Boostrap‘s minified CSS and JS files in the header and footer respectively in your WordPress site.
add_action( 'wp_enqueue_scripts', 'custom_load_bootstrap' );
/**
* Enqueue Bootstrap.
*/
function custom_load_bootstrap() {
wp_enqueue_style( 'bootstrap-css', '//maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css' );
wp_enqueue_script( 'bootstrap-js', '//maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js', array( 'jquery' ), CHILD_THEME_VERSION, true );
}
If CHILD_THEME_VERSION
is not set in your child theme, it can be done like so:
define( 'CHILD_THEME_VERSION', '2.3.0' );
