Frequently Asked Questions

Common questions about Hydrogen Calendar Embeds

Hydrogen Calendar Embeds implements the excellent Full Calendar for you, and tosses in a little Tippy.js and Popper to make things... well... pop.

No. All calendar events are maintained via your calendar source (Google Calendar, iCloud, Outlook, Airbnb, Clickup, etc.). This plugin just displays them beautifully.

Each calendar gets its own CSS selector: hycal-event-# where the # is the order of the listed calendar (starting with 0). So if you have two calendars in one, you can use hycal-event-0 to style the first, and hycal-event-1 to style the second calendar. If you use the cal_ids argument to set custom identifiers, those will be used instead of numeric indexes. For example, if you set cal_ids="soccer,baseball", you can use .hycal-calendar-soccer-event and .hycal-calendar-baseball-event to style each calendar's events specifically. Event pop-up tooltips also have calendar-specific classes: hycal-calendar-0-event-popup for easier styling of event pop-ups per calendar.

Add custom CSS to your theme to tweak to your desire.

Probably! With the fc_args parameter, you can pass in any FullCalendar argument to customize your calendar. See the FullCalendar documentation for a full list of options: https://fullcalendar.io/docs Contact me for requests for additional functionality, and let's see what we can create together!
