What is a recommended practice for alt text in web content?

Providing clear, descriptive text that conveys the image's meaning is considered a best practice for alt text in web content. Alt text is essential for accessibility because it allows users who rely on screen readers or other assistive technologies to understand the content and purpose of images. Descriptive alt text helps to create an inclusive experience by conveying the significance of the image in relation to the surrounding content, ensuring that all users, regardless of their ability, can access the same information.

When the alt text effectively summarizes the image's meaning, it enhances the overall understanding of the content for visually impaired users. This approach facilitates better navigation and enhances comprehension, helping to bridge the gap for those who cannot see the images.

In contrast, using generic phrases overlooks the specific context and meaning of each image, which may not provide the needed information. Leaving alt text blank for decorative images may be appropriate in certain cases, yet it should be done judiciously when the image truly does not add any meaningful content. Providing overly detailed alt text can also overwhelm users and obscure the essential message the image conveys, leading to confusion rather than clarity. The focus should be on a balance of succinctness and informative content.
