Mobile video resolution for request page and vendor page

I used the following additional CSS for listing page and it works.
how do i do the same for Request page and Vendor page??

@media screen and (max-width: 74.99em){
	.hp-template--listing-view-page .hp-listing__attribute iframe{
	    width: 100%;

Please try to change the listing word to the vendor word for vendors in this code snippet

Please try to change hp-template--listing-view-page on hp-template--request-view-page for requests if a request attribute is on the single request page

It works thank you so much yevhen
