<div className="theme-blocks">

### Essence

    "posts_per_page": 8,
    ...
}
```

## Image sizes

Ghost can handle [responsive image sizes](https://ghost.org/docs/themes/assets/#responsive-images-configuration), and this is defined in the `package.json` file, under the `image_sizes` property:

```json
"config": {
    ...
    "image_sizes": {
        "24": {
            "width": 24
        },
        "48": {
            "width": 48
        },
        "400": {
