Location Closure Calendar
JavaScript CSS Drupal
A calendar visual for use on the GW MFA location pages indicating which day(s) that location is closed for the current month. I implemented this as a browser-native Web Component that site editors can drop in to a page as a custom element and compose the visual output via HTML attributes.
The component contains logic to prevent rendering if the attributes are of the wrong data type (i.e. non-numbers for the month and dates), outdated or out of valid range.
