# --description--
|
|
|
|
In the last challenge, you learned that including an `alt` attribute when using `img` tags is mandatory. However, sometimes images are grouped with a caption already describing them, or are used for decoration only. In these cases, `alt` text may seem redundant or unnecessary.
|
|
|
|
When an image is already explained with text content or does not add meaning to a page, the `img` still needs an `alt` attribute, but it can be set to an empty string. Here's an example:
|
|
|
|
```html
|
|
<img src="visualDecoration.jpeg" alt="">
|
|
```
|
|
|
|
Background images usually fall under the 'decorative' label as well. However, they are typically applied with CSS rules, and therefore not part of the markup screen readers process.
|
|
|
|
**Note:** For images with a caption, you may still want to include `alt` text since it helps search engines catalog the image's content.

# --instructions--
|
|
|
|
Camper Cat has coded a skeleton page for the blog part of his website. He's planning to add a visual break between his two articles with a decorative image of a samurai sword. Add an `alt` attribute to the `img` tag and set it to an empty string. (Note that the image `src` doesn't link to an actual file - don't worry that there are no swords showing in the display.)
|
|
|
|
# --hints--
|
|
|
|
Your `img` tag should have an `alt` attribute.
|
|
|
|
```js
|
|
assert(!($('img').attr('alt') == undefined));
|
|
```
|
|
|
|
The `alt` attribute should be set to an empty string.
|
|
|
|
```js
|
|
assert($('img').attr('alt') == '');
|
|
```
