2. Step-by-Step Guide

Screen Reader is a form of assistive technology (AT) that renders text and image content as speech or braille output. Here are some common issues and how to fix them:

1. Non-Descriptive Links: If your links are not descriptive, screen readers may not accurately communicate the function of the link. For example, avoid using generic text like "click here."

Solution: Use the aria-label attribute to provide a descriptive name for the link.

<a href="https://example.com" aria-label="Visit Example Website">Click Here</a>

2. Missing Alternative Text For Images: Screen readers rely on the alt attribute to describe the content of an image. If this attribute is missing, the screen reader cannot provide a description.

Solution: Always include the alt attribute with a descriptive text.

<img src="image.jpg" alt="A description of the image">

3. Form Labels: If a form field does not have a label, screen readers won't be able to describe the field to the user.

Solution: Always use the <label> tag to describe form fields.

<label for="name">Name:</label>
<input type="text" id="name" name="name">

3. Code Examples

Example 1: Descriptive Links

<!-- Bad Practice -->
<a href="https://example.com">Click Here</a>

<!-- Good Practice -->
<a href="https://example.com" aria-label="Visit Example Website">Click Here</a>

The aria-label provides a descriptive name for the link.

Example 2: Alt Text for Images

<!-- Bad Practice -->
<img src="image.jpg">

<!-- Good Practice -->
<img src="image.jpg" alt="A description of the image">

The alt attribute describes the content of the image.

Example 3: Form Labels

<!-- Bad Practice -->
<input type="text" id="name" name="name">

<!-- Good Practice -->
<label for="name">Name:</label>
<input type="text" id="name" name="name">

The <label> tag describes the form field.
