Datepicker comes with the theme support with css variables. It provides two classes that are applied based on the chosen dark/light mode

To change variables, simply override the classes with your custom values.


  • When changing the properties, you only need to declare the class in the <style> tag, can be in global or scoped, depending on your needs
  • For the date picker to use dp__theme_dark, dark prop must be set to true
