Best Practices for Creating Accessible Experiences

Tutorial 5 of 5

Introduction

Goal of the Tutorial:

The primary goal of this tutorial is to guide you through the best practices for creating accessible web experiences. Accessibility is not an afterthought but a crucial aspect of web development that ensures your website can be used by all, including those with disabilities.

Learning Outcomes:

By the end of this tutorial, you'll be familiar with:
- The importance of web accessibility.
- Practical ways to improve the accessibility of your web content.
- How to use colors and typography effectively.
- Creating accessible forms and navigation.

Prerequisites:

Basic knowledge of HTML, CSS, and JavaScript is required. Familiarity with web design principles would be beneficial but not mandatory.

Step-by-Step Guide

Color and Typography:

Use high contrast colors: Ensure your text and background colors have sufficient contrast. This helps people with low vision or color blindness to read your content.

/* Good contrast */
body {
  color: #000000; /* black text */
  background-color: #ffffff; /* white background */
}

Avoid color as the only means of conveying information: For color-blind users, information conveyed only through color could be missed. Always provide an alternative.

<!-- Good: Information conveyed with text -->
<p style="color:red;">Error: Your password is too short.</p>

Use legible font sizes and styles: Avoid small font sizes and complex script fonts that are hard to read.

/* Good: Large, legible font */
body {
  font-size: 16px;
  font-family: Arial, sans-serif;
}

Forms and Navigation:

Use descriptive labels for form inputs: Labels should clearly describe what information is expected in the input field.

<!-- Good: Descriptive label -->
<label for="email">Email Address:</label>
<input type="email" id="email" name="email">

Ensure keyboard navigation: All functionality should be available using a keyboard. This helps users who cannot use a mouse or similar pointing device.

<!-- Good: Link can be accessed with keyboard -->
<a href="#" tabindex="0">Click me!</a>
