# --description--
|
|
|
|
Another positioning technique is to center a block element horizontally. One way to do this is to set its `margin` to a value of auto.
|
|
|
|
This method works for images, too. Images are inline elements by default, but can be changed to block elements when you set the `display` property to `block`.
|
|
|
|
# --instructions--
|
|
|
|
Center the `div` on the page by adding a `margin` property with a value of `auto`.
|
|
|
|
# --hints--
|
|
|
|
The `div` should have a `margin` set to `auto`.
|
|
|
|
```js
|
|
assert(new __helpers.CSSHelp(document).getStyle('div')?.margin === 'auto');
|
|
```
