Hello dear friends.

I added a code to the header and it works fine.  
The code I added;  
div class=“block22”  
button class=“block22” Block Button button  
div

But I want to hide this item from chat page on mobile. I really need help on this. All my attempts have failed.

Kind regards

Hello 👋

I am on my phone now but if I remember correctly you can target the `.has-full-page-chat` body class.

Mobile / CSS

```scss
body.has-full-page-chat {
  .block22 {
    display: none;
  }
}

```
