+description: Image Grid usage
+---
+
+The `img` shortcode has support for the `grid` attribute.
+The following values are supported:
+- `wide`
+- `last-third`
+- `first-third`
+- `first-two-thirds` (default)
+
+``` go-template
+{{</*img src="hero-graphic.webp" grid="wide"*/>}}
+```
+
+
+## Default
+By default, and image will take up the first two-thirds of the grid, allowing for call out content to its right.
+{{< img src="hero-graphic.webp">}}
+{{<call-out sideline="true">}}
+Here is an example of a callout to the side of an image.
+{{</call-out>}}
+
+
+## `wide`
+Providing the "wide" option, will make the image take up the full grid.
+
+{{< img src="hero-graphic.webp" grid="wide">}}
+
+
+## `last-third`
+Providing the "last-third" option, will make the image take up the last third of the grid, similar to a side call out.
+This makes it possible to place an image to the right of text.
+{{< img src="hero-graphic.webp" grid="last-third">}}
