CSS on Buttons implemented differently on overview and detail page

Hi,

I am working on a redesign page using Avada for WordPress.

On the overview page the text on the buttons are green, since my a:link css for links is green for the whole page also. But I want the text to be white. Blue button, white text. But this is not working, no matter what I try to do. Interestingly on the detail page of the job postings the buttons are looking fine.

Have you implemented the buttons on the detail page differently then on the overview page? What can I do?

Looking forward to your answer. Thank you in advance.

Many greetings from Germany
