Download Released

B21 is a minimalistic pastel-colored theme with basic Color module support,
inspired by the look and feel of the WordPress theme Twenty Twenty-One.



  • Navigate to Administration > Appearence > B21 settings
    (admin/appearance/b21/settings) to switch the Color scheme.

Good to know

  • On wider screens, B21 overwrites Backdrop's core layouts Moscone and Moscone
    Flipped to display the sidebar one-third wide instead of only 25%.
  • If you have many items in the Primary navigation dropdown menu, on medium wide
    screens there may not be enough space to see all items.

Overriding CSS and sub-theming
