Calendar CSS Styling
Smart.Calendar element represents a custom element representing a Calendar by displaying the days of a month of a given year.
The Smart.Calendar element requires the following file references to be placed on a web page in order for the custom element to be successfully registered and properly working:
- smart.element.js — this is the base file that defines the common architecture of all Smart custom elements. It is part of the repository ni-kismet/smart-element.
- smart.calendar.js — this file defines the functionality of the Smart.Calendar custom element.
- smart.button.js — this file defines the functionality of the Smart.Calendar custom element.
- smart.scrollbar.js — this file defines the functionality of the custom elements nested inside Smart.Calendar’s header section.
- smart.listbox.js — this file defines the functionality of the custom elements nested inside Smart.Calendar’s header section.
- smart.dropdownlist.js — this file defines the functionality of the custom elements nested inside Smart.Calendar’s header section.
- smart.tooltip.js — this file defines the functionality of Smart.Calendar’s tooltip custom element.
Smart.Calendar also requires the following style sheets in order to be displayed correctly.
- smart.base.css — the base style sheet file.
To create an instance of a Smart.Calendar custom element, ypu can use one of the following HTML structures:
Getting and setting properties dynamically
let customElement = document.querySelector('smart-calendar');
Properties are represented as members of the custom element’s instance object and can be accessed as such.
Here is an example showing how to get a property dynamically:
let selectedDates = customElement.selectedDates;
Here is an example showing how to set a property dynamically:
customElement.selectedDates = ["2017-07-2", "2017-09-7"];
let customElement = document.querySelector('smart-calendar');
Methods are represented as members of the custom element’s instance object and can be accessed as such.
Here is an example showing how to call a method:
Styling (CSS API)Smart HTML Elements use a pair of css files – smart.base.css and smart.[theme name].css. The base stylesheet creates the styles related to the element’s layout like margin, padding, border-width, position. The second CSS file applies the HTML Element’s colors, fonts, borders and backgrounds. The smart.base.css should be included before the second CSS file.

By default the animations for Smart.Calendar are disabled. They can be enabled by adding the CSS class called “animation” to the element, like so:
Smart.Calendar uses JS animations that can be manipulated using the “animationSettings” property of the element. The property represents an object with the following entries:
- startSpeed – the speed at which the animation begins until it reaches the threshold where it slows down. Default value is 0.2.
- easeThreshold – determines the threshold where the animation starts slowing down. Default value is 0.5 (meaning half the way of the animation)
- step – determines the scroll interval between animation frames or the step at which the animation progresses towards the end. Default value is 0.25.
- stepEaseSize – determines the easing coefficient used ti slow down the step after the threshold has been passed. Default value is 200.
- resetThreshold – a second threshold that will determine when the animation should start over or not. Default value is 0.2 ( meaning the animation will be restarted if 20% of it has passed).
