CSS styling not reflected on front end browser

Dear Sir/Madam
I am working a project and have been doing some CSS styling. However, I noticed all styling are reflected on cornerstone editor but when viewed on browser the styling are not reflected.
Please check attached image to see what I mean.

Hi @ASIDCam,

Thanks for reaching out.
As per the screenshot it seems that you have added the custom CSS code into the Page CSS for a specific page, which will not load for other pages. I would suggest you add the same into the Global CSS i.e. Theme Options > CSS to apply to all the pages.

Thanks
