Kimai uses the AdminLTE theme which can be configured in the file config/packages/admin_lte.yaml. You find the theme specific documentation here.

All Kimai specific theme settings will be available in the twig templates with the global kimai_context key, e.g.

{{ kimai_context.select_type }}

Aligning data in tables

Please stick to the following alignments in your listing:

Data type Alignment
Date Left
Datetime Left
Time Center
Money Right
Duration Right
Boolean Center
Text Left
Count (int) Center (badge)
Collections (Text) Left (label)

Always align the table header to the content cell.

Default theme color

Kimai supports the AdminLTE themes:

  • skin-blue
  • skin-blue-light
  • skin-yellow
  • skin-yellow-light
  • skin-green
  • skin-green-light
  • skin-purple
  • skin-purple-light
  • skin-red
  • skin-red-light
  • skin-black
  • skin-black-light

Each user can change the theme color to their wish (if they have the permission to change their preferences). It is recommended to leave the choice to the user, as colors and contrasts are not only a matter of personal choice but might also be necessary for people with visual impairments.

The default theme for new created users can be configured in the system settings.

Max. active entries warning

A small colored warning sign will be shown, if a user has an active timesheet.

The maximum amount of active timesheets can be configured with the setting timesheet.active_entries.hard_limit (called Permitted number of simultaneously running time entries, see System > Settings).


Kimai allows you to configure icons in several places (provided by Font Awesome 5) and ships with a pre-defined list of icon aliases to guarantee a consistent look.

The pre-defined icons aliases can be found in this IconExtension.

Icon aliases can be used by applying the icon filter, e.g.

<i class="{{ 'money'|icon }}"></i>
