Good Day.

I am using a Wordpress theme and I want to add my own custom CSS. Now I have tried adding my own separate stylesheet after all the other php stylesheet calls in the header.php file. I tried editing the stylesheet in Appearance>Editor, and I even added !important to ALL my styles. But Wordspress keeps overwriting my styles with the default stylesheet.

Now I read a bit about registering/enqueuing stylesheets in the functions.wp-styles.php but the code there is french to me...I do not know where to add my css...

Here is the code in the functions.wp-styles.php page: Your help will be greatly appreciated!

<?php
/**
 * BackPress styles procedural API.
 *
 * @package BackPress

/**

 *

 * @return bool True on success, false on failure.

Refer to the Codex entry for wp_enqueue_style().

Assuming you have a custom stylesheet, named custom.css, located in your Theme's root directory:

wp_enqueue_style( 'mytheme-custom', get_template_directory_uri() . '/custom.css' );

You would put this in functions.php, inside a callback, hooked into an appropriate callback, like so:

function wpse87681_enqueue_custom_stylesheets() {
    if ( ! is_admin() ) {
        wp_enqueue_style( 'mytheme-custom', get_template_directory_uri() . '/custom.css' );
    }
}
add_action( 'wp_enqueue_scripts', 'wpse87681_enqueue_custom_stylesheets', 11 );

You can play with the hook (you can use as late as wp_head) or priority (default is 10) to ensure that your custom stylesheet outputs after any other stylesheet you want to override. But, if you're just trying to override the default stylesheet, any appropriate hook, and any priority, should be fine, because the default stylesheet link is normally hard-coded in the document head in header.php.
