Hi there!
Is there a particular view that you want to target? I took a look at your calendar, and I noticed that in Month view, some of the items were being forced to font-weight: 700 by Divi’s styles.
When using web fonts, you need to load each weight that will be used. If the specified weight is not available, the browser will try to “fake it,” but this doesn’t work out so well on stylized fonts.
In any case, you can target the Events Calendar with CSS to change the font family or font weight with the following:
#tribe-events-content * {
font-family: Arial;
font-weight: normal;
}
If you wanted to target certain views only, you would need to modify that a bit.
For example, to just target the month view:
#tribe-events-content.tribe-events-month * {
font-family: Arial;
font-weight: normal;
}
Hope that helps! Let me know if you have further questions.
Thanks,
Sky
