React Data GridCustomising Colours & Fonts
Change the overall colour scheme and appearance of data.
The grid exposes many CSS --ag-*-color variables that affect the colour of elements. --ag-font-size and --ag-font-family control the default font for the grid.
Example
.ag-theme-alpine {
--ag-foreground-color: rgb(126, 46, 132);
--ag-background-color: rgb(249, 245, 227);
--ag-header-foreground-color: rgb(204, 245, 172);
--ag-header-background-color: rgb(209, 64, 129);
--ag-odd-row-background-color: rgb(0, 0, 0, 0.03);
--ag-header-column-resize-handle-color: rgb(126, 46, 132);
--ag-font-size: 17px;
--ag-font-family: monospace;
}The above code produces these results:
Key colour variables
Some of the most important colour variables are listed below. For the full list check the full CSS variables reference - every colour variable is ends with -color.
--ag-alpine-active-colorTypeCSS color (e.g. `red` or `#fff`) | (Alpine theme only) accent colour used for checked checkboxes, range selections, row hover, row selections, selected tab underlines, and input focus outlines in the Alpine theme |
--ag-balham-active-colorTypeCSS color (e.g. `red` or `#fff`) | (Balham theme only) accent colour used for checked checkboxes, range selections, row selections, and input focus outlines in the Balham theme |
--ag-material-primary-colorTypeCSS color (e.g. `red` or `#fff`) | (Material theme only) the primary colour as defined in the Material Design colour system. Currently this is used on buttons, range selections and selected tab underlines in the Material theme |
--ag-material-accent-colorTypeCSS color (e.g. `red` or `#fff`) | (Material theme only) the accent colour as defined in the Material Design colour system. Currently this is used on checked checkboxes in the Material theme |
--ag-foreground-colorTypeCSS color (e.g. `red` or `#fff`) | Colour of text and icons in primary UI elements like menus |
--ag-background-colorTypeCSS color (e.g. `red` or `#fff`) | Background colour of the grid |
--ag-secondary-foreground-colorTypeCSS color (e.g. `red` or `#fff`) | Colour of text and icons in UI elements that need to be slightly less emphasised to avoid distracting attention from data |
--ag-data-colorTypeCSS color (e.g. `red` or `#fff`) | Colour of text in grid cells |
--ag-header-foreground-colorTypeCSS color (e.g. `red` or `#fff`) | Colour of text and icons in the header |
--ag-header-background-colorTypeCSS color (e.g. `red` or `#fff`) | Background colour for all headers, including the grid header, panels etc |
--ag-disabled-foreground-colorTypeCSS color (e.g. `red` or `#fff`) | Color of elements that can't be interacted with because they are in a disabled state |
--ag-odd-row-background-colorTypeCSS color (e.g. `red` or `#fff`) | Background colour applied to every other row |
--ag-row-hover-colorTypeCSS color (e.g. `red` or `#fff`) | Background color when hovering over rows in the grid and in dropdown menus. Set to transparent to disable the hover effect. Note: if you want a rollover on one but not the other, use CSS selectors instead of this property |
--ag-border-colorTypeCSS color (e.g. `red` or `#fff`) | Colour for border around major UI components like the grid itself, headers; footers and tool panels. |
--ag-row-border-colorTypeCSS color (e.g. `red` or `#fff`) | Colour of the border between grid rows, or transparent to display no border |
There are a lot of colour variables - the easiest way to find the variable that colours a specific element is often to inspect the element in your browser's developer tools and check the value of its color or background-color properties.
Colour blending, Sass and CSS
The Sass API Colour Blending feature will automatically generate a few default values for colour variables based on the ones that you define. If you're using CSS you may want to set these values yourself for a consistent colour scheme:
-
Setting
--ag-alpine-active-colorin the Sass API will:- Set
--ag-selected-row-background-colorto a 10% opaque version - Set
--ag-range-selection-background-colorto a 20% opaque version - Set
--ag-row-hover-colorto a 10% opaque version - Set
--ag-column-hover-colorto a 10% opaque version - Set
--ag-input-focus-border-colorto a 40% opaque version
- Set
-
Setting
--ag-balham-active-colorin the Sass API will:- Set
--ag-selected-row-background-colorto a 10% opaque version - Set
--ag-range-selection-background-colorto a 20% opaque version
- Set
Generating semi-transparent colours
To make a semi-transparent version of a colour, you can use one of these techniques. If your colour is defined as a 6-digit hex value (#RRGGBB) convert it to an 8-digit hex value (#RRGGBBAA). If your colour is defined as a rgb value (rgb(R, G, B)) add a fourth value to specificy opactity (rgb(R, G, B, A)).
So for example, the color deeppink is hex #FF1493 or rgb rgb(255, 20, 147).
- 10% opaque:
#8800EE1Aorrgb(255, 20, 147, 0.1) - 20% opaque:
#8800EE33orrgb(255, 20, 147, 0.2) - 30% opaque:
#8800EE4Dorrgb(255, 20, 147, 0.3) - 40% opaque:
#8800EE66orrgb(255, 20, 147, 0.4) - 50% opaque:
#8800EE80orrgb(255, 20, 147, 0.5)
