In today's digital landscape, accessibility isn't just a buzzword – it's a fundamental requirement for creating truly impactful content. As we embrace the versatility of MDX (Markdown with JSX), ensuring our creations are accessible to all users, regardless of their abilities, becomes paramount. Enter mdx.do, your content powerhouse designed to help you effortlessly author, manage, and utilize MDX content with AI-powered workflows. While mdx.do empowers you with the tools, let's explore best practices for building inclusive MDX content.
At its core, MDX is a powerful way to write content that includes JSX. This means you can embed interactive components directly within your markdown, creating richer, more dynamic documentation, blogs, and applications. Think of the possibilities: a blog post with live code examples, an educational guide with interactive quizzes, or a product page with dynamic configurators.
However, with great power comes great responsibility. The very interactivity that makes MDX so compelling can also introduce accessibility challenges if not handled thoughtfully. An inaccessible website or application excludes users, impacting reach, usability, and even legal compliance. By prioritizing accessibility from the start, we ensure our MDX creations are valuable to everyone.
Here are key strategies to make your MDX content more inclusive:
When embedding JSX components within your MDX, always strive to use semantic HTML elements. This means using <button> for buttons, <nav> for navigation, <h1> for main headlines, and so on.
Why it matters: Semantic HTML provides crucial context for assistive technologies like screen readers. When a screen reader encounters a <div> that's styled to look like a button, it won't understand its role. A <button> element, however, directly communicates its interactive nature.
Example:
Instead of:
<div onClick={handleClick} style={{ cursor: 'pointer' }}>Click Me</div>
Use:
<button onClick={handleClick}>Click Me</button>
Any image you include in your MDX content, whether through Markdown syntax or a JSX component, must have descriptive alternative text (alt text).
Why it matters: Alt text is read aloud by screen readers, describing the image to users who cannot see it. It's also displayed if the image fails to load. Without alt text, visually impaired users miss crucial information.
Example (Markdown):
Example (JSX Component):
<Image src="graphic.png" alt="A bar chart showing revenue increasing over Q3" />
Interactive components embedded in MDX must be fully navigable and usable with a keyboard alone. This means:
Why it matters: Many users, including those with motor impairments, rely solely on keyboards for navigation.
Pay close attention to color contrast for text and interactive elements. Avoid using color as the sole means of conveying information.
Why it matters: Low contrast can make text unreadable for users with visual impairments or color blindness. Providing additional cues (like icons or underlines for links) ensures information is conveyed effectively.
Tool: Use a color contrast checker (many free online tools available) to ensure your colors meet WCAG (Web Content Accessibility Guidelines) standards.
Write your MDX content in clear, simple language. Avoid overly complex jargon where possible, and break up long paragraphs into digestible chunks.
Why it matters: This benefits users with cognitive disabilities, those with reading difficulties, and non-native speakers.
For complex interactive components where native HTML elements aren't sufficient, use ARIA (Accessible Rich Internet Applications) attributes to provide additional semantic information to assistive technologies.
Why it matters: ARIA roles, states, and properties can describe what an element is, what its current status is, and how it can be interacted with.
Example:
For a custom tab component:
<div role="tablist" aria-label="Section Tabs">
<button role="tab" aria-selected="true" id="tab-1" aria-controls="panel-1">
Section 1
</button>
<div role="tabpanel" id="panel-1" aria-labelledby="tab-1">
Content for Section 1
</div>
</div>
The best way to ensure your MDX content is accessible is to test it with a variety of tools and, ideally, with actual users.
While mdx.do doesn't automatically make your content accessible (that's your job!), it provides the foundational tools to streamline your MDX workflows, allowing you to focus more on content quality and accessibility.
mdx.do offers a suite of AI-powered agents and utilities designed to help you create, manage, and utilize MDX content more effectively. This includes features for parsing, transforming, and integrating MDX into your workflows.
You can use mdx.do to:
Building accessible MDX content is an ongoing journey, not a one-time task. By adopting these best practices and leveraging powerful tools like mdx.do, you can create dynamic, interactive experiences that are truly inclusive, reaching a wider audience and providing a better experience for everyone.
