Links

Events may have locations and URLs. If you embed the calendar into a website, you can choose where the clicked link opens the page.
Open the linked document in the same frame as it was clicked. Open the linked document in the parent frame. Open the linked document in a new window or tab. Open the linked document in the full body of the window.

Custom Style with CSS

You can change the color of your calendar and many more properties using CSS. Your customization has priority over the Skin you choose. Below, you can choose from a few customizations we prepared for you.

• You can change the background color of the calendar.
• You can change the color of the elements which can be clicked.
• You can change the background color of the current date.
• If you like to have a different color for the days, you can specify this, too.
• Some days of the calendar have a different color if they are not within the month.

You can specify your own CSS properties if you like.

Loading Animation

In some cases, the server takes quite a time to load the calendar. In case the server uses a free plan on Heroku, the server needs to start first.

Month, Week, Day and Agenda View

The Month view is the default. However, you can choose to show a different view in the beginning. Choose one: Month Week Day Agenda

It might be that you do not want to show all controls for the users to see. Choose here which controls you would like to display:

Month Week Day Agenda Next Previous Today Date

Hosting the Specification

The calendar can be generated not only using the url but also through a JSON or YAML specification which resides in a file. The customization from above generates this specification:

You can download this specification and place it somewhere on the web. This way you are still in control over the customization of the calendar after you shared the link, e.g. on GitHub in a Gist. Once you have placed the specification somewhere online, you can create a link like this one .
