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:
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.
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.)
