Theming and Styling

AdapTable makes it easy for you to switch between themes or create your own

A Theme is essentially a collection of css variables that AdapTable exposes, and you can customise.

You can have more css theme files imported in the app without them overriding each-other.

System Themes

AdapTable ships with 2 themes: light (the default) and dark.


To use the Dark Theme, specify dark as the Current Theme in the Theme section of Predefined Config

Make sure to import the AdapTable dark.css file and, if using ag-Grid, also to import the associated dark vendor theme.


AdapTable supports both ag-Grid's new Alpine and the older Balham themes in their dark versions.

import '@adaptabletools/adaptable/index.css';
import '@adaptabletools/adaptable/themes/dark.css';
import '@ag-grid-community/all-modules/dist/styles/ag-grid.css';
import '@ag-grid-community/all-modules/dist/styles/ag-theme-balham.css';
import '@ag-grid-community/all-modules/dist/styles/ag-theme-balham-dark.css';
export default {
Theme: {
CurrentTheme: 'dark',
} as PredefinedConfig;

You do not need to provide a VendorGridClassName when using either of the System Themes as this is done for you.

This means that you only need provide themes for AdapTable and / or the Vendor Grid if you are unhappy with the defaults that we provide.

Applying a Theme

When AdapTable applies a theme, it sets the ab--theme-<THEME_NAME> css className on the document HTML element - so only one theme will be applied at any given time.

Creating a Custom Theme

In order to write a theme you need to provide the name as an html element and also provide the same value in '--ab-theme-loaded' property.

The definition is as follows:

html.ab--theme-<THEME_NAME> {
--ab-theme-loaded: <THEME_NAME>;

So, for example, if you have a blue theme you will provide the following css:

html.ab--theme-blue {
--ab-theme-loaded: blue;

You also need to make sure that the theme name is included in the UserThemes property in the Theme section of Predefined Config, together with a description (the text that appears in the Theme dropdown) and - optionally - the name of the vendor grid theme that you want to load simultaneously with the Theme.

export default {
Theme: {
Description:"Blue Theme",
VendorGridClassName: 'ag-theme-blue'
CurrentTheme: 'blue'
} as PredefinedConfig;

The theme name cannot contain whitespace characters - it needs to be a string which can be used as a css className

CSS Variables

AdapTable uses CSS Variables in order to allow you to build your own custom themes.

There are a huge number of css variables that are available.

For easy identification purposes every CSS Variable starts with either '--ab-' or '--ab__'

This example shows the contents of the dark theme.

Example Theme

html.ab--theme-dark {
/* this is here so we detect when the dark theme has been correctly loaded */
--ab-theme-loaded: dark;
/* the background for the whole Adaptable Dashboard - only used once */
--ab-dashboard__background: #232323;
/* default background color to be used in dialogs, panels, inputs, etc */
--ab-color-defaultbackground: #3e444c;
/* color for text displayed on the default background */
--ab-color-text-on-defaultbackground: #f7f7f7;
/* the most used color - used for example, in dashboard toolbars + a light and dark variation */
--ab-color-primary: #262d2f;
--ab-color-primarylight: #2d3537;
--ab-color-primarydark: #1c2021;
/* color for text displayed over the primary color */
--ab-color-text-on-primary: #f7f7f7;
/* a color not so often used - mostly used for making things stand out
these properties are NOT used in the dark theme but you might want to override in your themes
e.g. to change Dashboard Header colour & text, set '--ab-color-secondary' and '--ab-color-text-on-secondary'*/
// --ab-color-secondary: #f7f7f7;
// --ab-color-secondarylight: #07456d;
// --ab-color-secondarydark: #f7f7f7;
/* color for text displayed over the secondary color */
// --ab-color-text-on-secondary: #262d2f;
// --ab-color-text-on-secondarylight: #f7f7f7;

In addition to the above variables, the following are also available

html.ab--theme-my-theme {
--ab-theme-loaded: my-theme;
/* we define a set of spacings, which you can customise to suit your needs */
--ab-space-0: 0px;
--ab-space-1: 4px;
--ab-space-2: 8px;
--ab-space-3: 16px;
--ab-space-4: 32px;
--ab-space-5: 64px;
--ab-space-6: 128px;
--ab-space-7: 256px;
/* also a set of font sizes */
--ab-font-size-0: 0.5rem; /* 8px for 1rem=16px */
--ab-font-size-1: 0.625rem; /* 10px for 1rem=16px */
--ab-font-size-2: 0.75rem; /* 12px for 1rem=16px */
--ab-font-size-3: 0.875rem; /* 14px for 1rem=16px */
--ab-font-size-4: 1rem; /* 16px for 1rem=16px */
--ab-font-size-5: 1.25rem; /* 20px for 1rem=16px */
--ab-font-size-6: 1.5rem; /* 24px for 1rem=16px */
--ab-font-size-7: 2.25rem; /* 36px for 1rem=16px */
/* use this to specify the font family you want for Adaptable*/
--ab__font-family: inherit;
/* customise the border radius for some of Adaptable elements */
--ab__border-radius: var(--ab-space-1);

That's all the css you have to write for defining a theme - in fact, you can choose which of the above colors/variables to define - you don't have to define them all.

Start incrementally, and work your way up as you need - use the dark theme as an example.

Using SASS

When using sass, in order to use sass variables as values for css properties, you have to use interpolation:

$theme-color: #fea7ff;
html.ab--theme-light {
--ab-cmp-dashboardpanel_header__background: #{$theme-color}; /* use interpolation ! */

Styling icons

Adaptable uses inline SVG for icons, since that's very performant and doesn't require any additional download.

However, you might want to style icons differently - in this case, you can customize that through css. Every icon has the ab-Icon css class, and also ab-Icon--NAME where NAME is the name of the icon. So for example, if you want to use a background image, you can do the following:

.ab-Icon--build path {
visibility: hidden; /* to hide the contents of the actual SVG */
.ab-Icon--build {
background-image: url(...);
background-size: cover;

(See a demo of this in action)
