A theme for Bootstrap for designing, styling and creating modern map apps. This project contains CSS classes that can be used with Bootstrap to quickly build responsive map apps with a great UI and UX. You can create a variety of custom apps with different themes, layouts and colors simply by applying the calcite-maps-xxx classes to existing Bootstrap HTML elements. A number of Bootstrap components have been extended making it easy to add, remove and synchronize navbar items, dropdown menus and panels. The framework is also designed to work well with mapping components (zoom, home, attribution...) and provides additional features such as collapsible panels and "Full Map" to hide the UI for full map viewing. The Sass build creates a calcite-maps-xxx.css library as well as a custom calcite-maps-bootstrap.css build of Bootstrap - which is optional to use. The framework is designed to work with the ArcGIS JS 3.x, 4.x and Esri-Leaflet API.
