As you can see the styles are applied to the current tag
This means they will only show up on the current page (Homepage in this case)
I would reccomend removing the current tag before applying the styles. Since you want the changes to appear on all pages. Not just the current page (homepage).
To do this click the selector field above the style tags.
and select this one
Do this before applying the final style changes above.
Hope that helps!
Let me know if you get it working.
