This page is a copy of the v32 theme docs, and needs updating for the Theming API.

Styling Text Inputs

Text inputs can be styled with a combination of CSS variables and selectors:

.ag-theme-quartz {
    --ag-borders-input: dotted 2px;
    --ag-input-border-color: orange;
}
.ag-theme-quartz .ag-text-field-input {
    background-color: rgb(255, 209, 123); /* light orange */
}
.ag-theme-quartz .ag-text-field-input::placeholder {
    color: rgb(155, 101, 1); /* darker orange */
}

The CSS variables relevant to styling text inputs are:

--ag-borders-input
a CSS border style and size (e.g. `solid 1px` or `none`)
Draw borders around inputs. Set this to a border style and thickness, e.g. solid 1px to enable borders, or none to disable borders.
--ag-input-border-color
CSS color (e.g. `red` or `#fff`)
Colour for borders around inputs, if enabled with --ag-borders-input
--ag-borders-input-invalid
a CSS border style and size (e.g. `solid 1px` or `none`)
Draw borders around inputs when their content has failed validation. Set this to a border style and thickness, e.g. solid 2px to enable borders. Set to none to disable borders but ensure that you have added styles to differentiate invalid from valid inputs.
--ag-input-border-color-invalid
CSS color (e.g. `red` or `#fff`)
The color for the border around invalid inputs, if enabled with --ag-borders-input-invalid
--ag-invalid-color
CSS color (e.g. `red` or `#fff`)
The color applied to form elements in an invalid state
--ag-input-disabled-border-color
CSS color (e.g. `red` or `#fff`)
The border around disabled text inputs
--ag-input-disabled-background-color
CSS color (e.g. `red` or `#fff`)
The background colour of disabled text inputs
--ag-input-focus-box-shadow
CSS box-shadow value (e.g. `0 5px 10px black`)
box shadow around focussed inputs
--ag-input-focus-border-color
CSS color (e.g. `red` or `#fff`)
Colour of the border around focussed inputs. Set to var(--ag-input-border-color) if you do not want to change the border colour on focus.

Styling Checkboxes

The default styles of the grid disable the browser's native checkbox widget and create a custom appearance using icon fonts (see below for how to disable this).

See the Custom Icons documentation for how to replace the checkbox icons - the icons used are checkbox-checked, checkbox-unchecked, checkbox-indeterminate.

The colours can be controlled using the following CSS Variables:

.ag-theme-quartz {
    --ag-checkbox-background-color: yellow;
    --ag-checkbox-checked-color: red;
    --ag-checkbox-unchecked-color: darkred;
    --ag-checkbox-indeterminate-color: grey;
}

Styling Radio Buttons

Radio Buttons, such as those in the chart settings UI, are specialised checkboxes. They respond to the same colour variables as demonstrated above. They use the radio-button-on and radio-button-off icons.

Styling Toggle Buttons

Toggle Buttons, such as the "Pivot Mode" toggle in the above example, are specialised checkboxes. They respond to the same checkbox colour variables. In addition, they expose a few more variables for advanced customisation:

--ag-toggle-button-border-width
CSS length (e.g. `0`, `4px` or `50%`)
size of the toggle button outer border
--ag-toggle-button-on-border-color
CSS color (e.g. `red` or `#fff`)
colour of the toggle button outer border in its 'on' state
--ag-toggle-button-off-border-color
CSS color (e.g. `red` or `#fff`)
colour of the toggle button's outer border in its 'off' state
--ag-toggle-button-on-background-color
CSS color (e.g. `red` or `#fff`)
colour of the toggle button background in its 'on' state
--ag-toggle-button-off-background-color
CSS color (e.g. `red` or `#fff`)
colour of the toggle button background in its 'off' state
--ag-toggle-button-switch-background-color
CSS color (e.g. `red` or `#fff`)
colour of the toggle button switch (the bit that slides from left to right)
--ag-toggle-button-switch-border-color
CSS color (e.g. `red` or `#fff`)
border colour of the toggle button switch (the bit that slides from left to right)
--ag-toggle-button-width
CSS length (e.g. `0`, `4px` or `50%`)
width of the whole toggle button component
--ag-toggle-button-height
CSS length (e.g. `0`, `4px` or `50%`)
height of the whole toggle button component

Using Browser Native Checkboxes or Creating Your Own

The default styles in ag-grid.css contain many CSS rules to implement the --ag-checkbox-* and --ag-toggle-button-* variables described above. If you want to use the browser's default UI or create your own then it's easier to start from a blank slate rather than attempting to override the default styles.

To achieve this, use the ag-grid-no-native-widgets.css CSS file instead of ag-grid.css.

Users of the Sass API can pass suppress-native-widget-styling: true to accomplish this.
