JavaScript Data Grid: Customising 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 variable reference - every colour variable is ends with -color.

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-color in the Sass API will:
- Set --ag-selected-row-background-color to a 10% opaque version
- Set --ag-range-selection-background-color to a 20% opaque version
- Set --ag-row-hover-color to a 10% opaque version
- Set --ag-column-hover-color to a 10% opaque version
- Set --ag-input-focus-border-color to a 40% opaque version
Setting --ag-balham-active-color in the Sass API will:
- Set --ag-selected-row-background-color to a 10% opaque version
- Set --ag-range-selection-background-color to a 20% opaque version

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)) convert it to rgba (rgba(R, G, B, A)).

So for example, the color deeppink is hex #FF1493 or rgb rgb(255, 20, 147).

10% opaque: #8800EE1A or rgb(255, 20, 147, 0.1)
20% opaque: #8800EE33 or rgb(255, 20, 147, 0.2)
30% opaque: #8800EE4D or rgb(255, 20, 147, 0.3)
40% opaque: #8800EE66 or rgb(255, 20, 147, 0.4)
50% opaque: #8800EE80 or rgb(255, 20, 147, 0.5)
