Responsive price list error

Hello!

I hope someone can help me. I have an issue with the font colour of the price in the tablet formatting. The font colour is the same as the background colour. I have tried to change it in css, but was not able to do it..

This is a screenshot of the information that the inspect option in Google Chrome gives me:

If I disable the colour it looks fine! Screenshot:

Sadly I can’t seem to manage this in CSS or find the corresponding part in the theme code…

I do not have this issue in desktop or mobile formatting. But the strange thing is this: when I was slowly decreasing the size of my browser to see when this problem happens, I found out that it only happens in the largest part of the tablet width range, and not in the smallest part. I do not know how to explain this more clearly, please try out decreasing and increating the browser size to see what I mean. Looking at the source code, the colour value in the first screenshot has changed to #fff, which is exactly what I need.

If there’s something unclear or if you need more information, just let me know!

Thanks in advance!
