-Styling the Image component is not that different from styling a normal `<img>` element, but there are a few guidelines to keep in mind:
-
-**Pick the correct layout mode**
-
-The image component has several different [layout modes](/docs/api-reference/next/image.md#layout) that define how it is sized on the page. If the styling of your image isn't turning out the way you want, consider experimenting with other layout modes.
-
-**Target the image with className, not based on DOM structure**
+Styling the Image component is similar to styling a normal `<img>` element, but there are a few guidelines to keep in mind:
 
-For most layout modes, the Image component will have a DOM structure of one `<img>` tag wrapped by exactly one `<span>`. For some modes, it may also have a sibling `<span>` for spacing. These additional `<span>` elements are critical to allow the component to prevent layout shifts.
+**Use `className` or `style`, not `styled-jsx`**
 
-The recommended way to style the inner `<img>` is to set the `className` prop on the Image component to the value of an imported [CSS Module](/docs/basic-features/built-in-css-support.md#adding-component-level-css). The value of `className` will be automatically applied to the underlying `<img>` element.
+In most cases, we recommend using the `className` prop. This can be an imported [CSS Module](/docs/basic-features/built-in-css-support.md#adding-component-level-css), a [global stylesheet](/docs/basic-features/built-in-css-support#adding-a-global-stylesheet), etc.
 
-Alternatively, you can import a [global stylesheet](/docs/basic-features/built-in-css-support#adding-a-global-stylesheet) and manually set the `className` prop to the same name used in the global stylesheet.
+You can also use the `style` prop to assign inline styles.
 
-You cannot use [styled-jsx](/docs/basic-features/built-in-css-support.md#css-in-js) because it's scoped to the current component.
