WordPress: How to Add CSS to a Specific Page 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.

PHP Snippet: Apply CSS to a Page URL That Contains “string”

add_action( 'init', 'bbloomer_apply_css_if_url_contains_string' );
 
function bbloomer_apply_css_if_url_contains_string() {
 
$url = $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
 
if ( false !== strpos( $url, 'string' ) ) {
    echo '<style type="text/css">
         .entry-title { color: red }
         </style>';
} 
 
}

Where to add custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.

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

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?

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

    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} </style>'; } }

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?
