CSS is not being rendered

Hello All,

My problem is after adding CSS class to some tags and then added the elements selectors in my CSS files, they are not being rendered on my website. All the previous CSS I did is working but any new ones aren't being rendered at all. It is as if they're not even there.

Has anyone else encountered this issue and if so how did you solve it?

Thanks for any help, it is much appreciated.

Thank you

Moe
