Custom CSS not working for mobile view

Hi! I am using custom CSS to have buttons width occupy 100% of the screen on mobile view, and also for the page logo in header to change on specific pages. For some reason nothing is working. This is the code:

/* Header logo */
@media only screen and (max-width:767px) {
  body#collection-636997b0d30783082de18988.page-faqs .header-title-logo a {
    content: url('https://static1.squarespace.com/static/62adaf0603d8e10682bd2f64/t/65d5c00bc018f861344f6478/1708507147165/Logo_TGO-07.png') !important;
    max-width: 200px;
  }
}

/* Button width */
@media only screen and (max-width: 767px) {
    .list-item-content__button.sqs-block-button-element.sqs-block-button-element--medium.sqs-button-element--primary {
        width: 100%;
    }
}

Any help appreciated!

Thank you!

Use this code for mobile

@media screen and (max-width:767px) {
body#collection-636997b0d30783082de18988 header#header img {
    content: url(https://static1.squarespace.com/static/62adaf0603d8e10682bd2f64/t/65d5c00bc018f861344f6478/1708507147165/Logo_TGO-07.png);
}
}

With button

Which page are you referring to? I don't see button on FAQs page

As for the button, is the one on the contact page  https://thegramounce.com/contact

But I think I was able to solve it. Thanks again!
