Hide 'Create Topic' on home page?

You can use your browser’s Style Inspector. It shows that the declaration is overwritten by a more specific one on mobile: [Screenshot from 2021-04-07 18-57-16] So you can either use the more specific declaration for mobile yourself: body:not([class*="category-"]) .list-controls .container #create-topic { display: none; } Or give your general declaration priority with the !important property: body:not([class*="category-"]) #create-topic { display: none !important; }
