All `img` elements **must** have an `alt` attribute. The text inside an `alt` attribute is used for screen readers to improve accessibility and is displayed if the image fails to load.
**Note:** If the image is purely decorative, using an empty `alt` attribute is a best practice.
Ideally the `alt` attribute should not contain special characters unless needed.
Let's add an `alt` attribute to our `img` example above:
`<img src="https://www.freecatphotoapp.com/your-image.jpg" alt="A business cat wearing a necktie.">`
