# Fills & Borders

This section describes how to change the fills and borders of chart elements.

#### Fills & Borders

```ts
// Angular entry point file
import '@angular/compiler';
import { bootstrapApplication } from '@angular/platform-browser';

import { AppComponent } from './app.component';

bootstrapApplication(AppComponent);
```

[Live example: Fills & Borders](https://www.ag-grid.com/charts/angular/fills-borders/examples/fills-borders)

In the above example:

- A border is drawn around the series area with a corner radius and no padding.
- A fill and corner radius are applied to the chart title and subtitle, with a border applied to the title only.
- A border, fill and corner radius are applied to the [Legend](https://www.ag-grid.com/charts/angular/legend/), with padding between the border and items provided as a single number.
- A border, fill and corner radius are applied to the series labels and [axis labels](https://www.ag-grid.com/charts/angular/axes-labels/) with padding defined for each of the top, right, bottom and left.
- An [item styler](https://www.ag-grid.com/charts/angular/stylers/#item-stylers) is used to override the styling of series labels for names starting with the letter 'D' and 'E'.

## Fills

```js
{
    label: {
        color: '#333', //font colour
        fill: '#badaff', // fill colour
        fillOpacity: 0.8,
    },
}
```

See [Series Fills](https://www.ag-grid.com/charts/angular/fills/) for details of the available fills types, including [patterns](https://www.ag-grid.com/charts/angular/fills/#patterns) and [gradients](https://www.ag-grid.com/charts/angular/fills/#gradients).

## Borders

```js
{
    border: {
        enabled: true,
        stroke: '#2c79d5',
        strokeWidth: 1,
    },
}
```

## Padding

Padding can be defined as a single number to be applied to all sides of the element, or as an object with values for `top`, `right`, `bottom` and `left`.

```js
{
    padding: 4, //padding of 4px on all sides
}
```

```js
{
    padding: {
        top: 4,
        right: 6,
        bottom: 2,
        left: 6,
    },
}
```

### Item Styler

Individual axis and series labels can be customised using a [Styler](https://www.ag-grid.com/charts/angular/stylers/#item-stylers) callback.

```js
itemStyler: (params) => {
    if (params.datum.name.startsWith('D')) {
        return {
            /* ... */
            fill: {
                type: 'gradient',
                rotation: 90,
                colorStops: [{ color: '#c56600', stop: 0 }, { color: '#fb9323' }],
            },
        };
    }
}
```
