Fix initial linting errors in the scaffold

[johnwatkins0]

Describe the bug

On a clean installation of the scaffold, after running npm install, running an initial commit is blocked because of linting errors in the theme, specifically 3 CSS errors.

I suggest fixing these errors or at least adding ignore comments to them so that an initial commit can be made without friction.

Steps to Reproduce

1. Make a clean install of the scaffold
2. Run npm install
3. Make a commit and you'll see lint staged failing due to several CSS errors
