Can't add css to my page

Hello, I’ve added some css code to the “aditional css” part in the theme and it worked just fine. however a couple of days ago, when i added new code it did nothing. i’ve tried different things but nothing changed. the code i put initially still works and i can change it and see the results just fine. the problem is any new code i put in. i have cleared my cache but the problem is still there. How can i solve this? thank you.

Hello there,

Thank you for contacting us about our theme Talon. I am happy to help with your queries.

Can you check all your custom CSS code with this tool to ensure the validity and you should fix the error when it presents?
