I have created a custom page on WordPress, I have just copied page.php and added my slug at the end of page.php so my custom page is page-my-custom-page.php.

Inside my custom page I have a form with select boxes, buttons and other HTML elements.

I have ElementorPro plugin. What I want to do is to use the Elementor css classes on my custom page HTML elements.

Is this possible? How can I do that?

Many thanks.
