How to Read Alt Text: A Comprehensive Guide

Alt text (alternative text), also known as “alt attributes” or “alt descriptions,” is a text description of an image on a webpage. The purpose of alt text is to provide a means for people who are visually impaired to understand the content of images on a webpage. It is essential for web accessibility and is required by law in certain countries. In this guide, we will discuss how to read alt text.

How to Identify Alt Text

Identifying alt text is quite simple, as it often appears as a tooltip or a caption when hovering over the image. If the alt text is not visible, you can use a screen reader, which is a tool that reads the content of a webpage aloud, including the alt text. Screen readers are widely available and can be used on various platforms and devices.

How to Evaluate the Quality of Alt Text

The quality of alt text can vary depending on the webpage’s content and style. However, there are some essential criteria to evaluate the quality of alt text. First, alt text must be concise, accurate, and relevant to the image. It should describe the essential purpose and meaning behind the image, not just its appearance. Second, alt text must be grammatically correct and free of spelling errors. Lastly, alt text must not contain any unnecessary information, such as the image’s file type or dimensions.

In conclusion, understanding how to read alt text is crucial for web accessibility and inclusivity. Alt text helps people with visual impairments to understand the content of images on a webpage, and it is required by law in some countries. Identifying and evaluating the quality of alt text is relatively simple and requires minimal effort.
