Modifying the look of Appointments+

I need to make changes to the way Appointments+ look on my site. Here's what's going:

1. Up top where the client can see the appointment he/she made, the categories listed above the appointment took on a strange color pattern that makes it impossible to see the category names. How can I change this?

2. When an appointment is selected the words, "Please check the appointment details below and confirm:" will appear. But the words are too large and the sentence goes clear across my screen. How can I change the size of this font and maybe change the sentence to say something different?

You can visit the website at ihealthexpress.com, and when you leave the "home" page a floating menu will appear to the right of the screen. That floating menu will lead you to the calendar.

I am comfortable with Wordpress but not strong with coding. Hope this is easy! :slight_smile: Thanks
