• alt attribute: refers to the text to be displayed when the image cannot be loaded, as a reading description for screen readers.

For example:

<img src="image/logo.jpg" alt="网站的Logo">

In the above example, we used the relative path "image/logo.jpg" to tell the browser to load from the image folder on the server An image named "logo.jpg". The "alt" attribute next to the image is descriptive and will be displayed if the image fails to load.

• Add meaningful and descriptive names to the images and use alt attributes Rely on color to convey important information
