add css for one page only

You can target the homepage by adding .home in front of your CSS declaration.

Let me know how it goes.

You need a space after .home and before your other selectors.

For example, to make the menu links purple only on the homepage:

.home .primary-navigation a {
  color: #bb00bb;
}

Having a space means you’re targeting an element further down the HTML structure. (DOM)

Thanks, I tried this but it still affects all pages. In my case, I want to add right padding 40px to the columns in the homepage and no padding in the columns in the pricing page. I added home. with space as you suggested but it still affects all pages.

Could you please paste the CSS that isn’t working as you expect here, in a Code block? I’ll be glad to have a look.

Please also provide a mockup/image clearly showing where exactly you are looking to add padding on the homepage. Thanks!
