Hi Coralie,
Thanks for getting in touch! I’d be happy to help but would you please post this question to our Events Calendar PRO forum? We use the Pre-Sales forum to answer general questions about the features of our premiums forums for people interested in purchasing them.
If you have not purchased one of our premium plugins, you can post in ourĀ open source forum. We review that forum weekly to check for bug reports. If you need more in-depth support you will need to purchase a license.
In the meantime, it sounds like CSS will help resolve this issue. Please do check out our Themer’s Guide (which includes information on customizing calendar styles) and this article for tips on how to target CSS classes in the calendar.
Cheers!
Geoff
