The alt attribute is used in HTML to provide alternative text for an image or other media that is embedded in a web page. The purpose of the alt attribute is to provide a text description of the media for users who are visually impaired or who are using assistive technologies such as screen readers.
The syntax for using the alt attribute is as follows:
<source-element src="URL" alt="alternative text">Here, source-element refers to the specific HTML element (e.g. <img>, <audio>, <video>) that you are using to embed the media file in your web page. The src attribute is used to specify the URL or file path of the media file, and the alt attribute is used to provide alternative text for the media.
For example, if you wanted to embed an image of a cute kitten in your web page, you might use the following code:
<img src="https://www.example.com/images/kitten.jpg" alt="A cute kitten">In this example, the alt attribute provides a text description of the image for users who cannot see the image or who are using assistive technologies. If the image cannot be loaded for some reason, the alternative text will be displayed instead.
It’s important to provide meaningful alternative text for your media files, as this can improve the accessibility of your web page and make it easier for all users to understand the content. When writing alternative text, try to provide a concise and accurate description of the media that conveys the essential information.
