WordPress: How to Add CSS to a Specific URL

This is an interesting topic. A WordPress/WooCommerce client could not add CSS via the usual way. In fact, Gravity Forms plugin (and in particular the “directory” extension), stores entries in the database BUT the directory page and the entries filtered list have the same classes, ids, and cannot be “targeted” with CSS.

Long story short, and Gravity Form or not Gravity Form, here’s the snippet you can use to add CSS to any WordPress page as long as you know its URL.

Let’s say I want to apply some red font to the page title if the URL contains the string “yo”. All I need is the snippet below, where I use “yo” as the search string. That’s it!

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101

  1. Hi! I should add the domain name to “SERVER NAME” and the path to “SERVER URI”??

    1. Sorry for the confusion. The only thing you need to change is the “abc” search string, so if your URL is example.com/whatever you need to replace “abc” with “whatever“, and then write the CSS that you want to apply. That’s it!

  2. NIIIIIIce thanks man!

  3. Boom!!!! You are the man!
    Thank you so much. I had a Javascript instead if this amazing function.
    I just added this to load it in the head.

    function inline_css() {
      echo "<style>.html{ color: red } }</style>";
    add_action( 'wp_head', 'inline_css', 0 );


  4. A very interesting thing happened when I applied the code. I used it for the WooCommerce My Account sub-page “orders” just to change an Elementor element I put above the my account shortcode. It broke the WooCommerce orders table, but only on mobile Safari and mobile Chrome and only the “display: block” attribute did not work anymore. When I changed the font of the table the CSS showed, but the “display” attribute is somehow broken. When I looked at it in Chromes inspect window with mobile view the table was normal. Very odd behaviour. On other pages with tables everything works fine when I use this code. Do you maybe know why the “display” attribute won’t work on the WooCommerce order table because of this code?

    1. It depends on many things, and first of all on the CSS you applied. Want to share it here maybe?

      1. Sure. I applied CSS to a row above the orders content from Elementor (which I made to as a navigation through the My Account part), to change the background-color and color of the “buttons” when the specific URL is activated. (you can see it here what happens, if the php code is applied: https://www.magentacloud.de/lnk/TwCFjgXz#file)

        I applied this code:

        add_action( 'init', 'bbloomer_apply_css_if_url_contains_bestellungen' );
        function bbloomer_apply_css_if_url_contains_bestellungen() {
        $url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
        if ( false !== strpos( $url, 'bestellungen' ) ) {
            echo '<style type="text/css">
                 .elementor-11 .elementor-element.elementor-element-23f25a3 > .elementor-widget-container {background-color:#000 !important} .elementor-11 .elementor-element.elementor-element-23f25a3 .elementor-icon-box-content .elementor-icon-box-title {color:#fff !important} .elementor-11 .elementor-element.elementor-element-23f25a3 .elementor-icon i {color: #fff;} .woocommerce-page.table.shop_table_responsive tr td {display:block !important}

    1. Where did you place your CSS?

  6. Hi! I used this snippet for changing CSS on specific pages where i need. It works perfect BUT:
    Can I ask if using it multiple times in a short period gets the Imunify360 to block the ip?
    Because that does happen, it changes the CSS of said page and nothing brakes, so before I freak out again I just want to make sure it’s just a safety measure and that I shouldnt worry? Or should I proceed in another way?

    1. Hi Vanessa, no it shouldn’t

  7. Hi, just wanted to let you know that I used something similar ages ago and wanted to use that code again and I was having a blank/couldn’t remenber the exact coding I did, cause I went withouth coding for years, bla bla bla.
