Why Accessibility Matters
Let’s talk about accessibility and why it’s such a big deal. Think about this: the internet is a massive part of our lives, but for someone who’s visually impaired, it’s not always as easy to navigate as it should be. Accessibility is all about making sure everyone can use your site or app, no matter their abilities. And for visually impaired users, assistive technologies like screen readers act as their gateway to the digital world.
When you design with accessibility in mind, you’re not just ticking boxes—you’re opening up your product to more people and making the world a little more inclusive. Plus, you’re probably meeting legal standards like the Web Content Accessibility Guidelines (WCAG). Win-win, right?
Getting to Know Assistive Technologies
Now, let’s dive into how visually impaired users actually interact with your app. Screen readers are the big players here. These tools read text out loud or convert it to Braille, letting users "see" the page through sound or touch. There are a few popular ones out there:
- NVDA: Free and open-source, perfect for Windows users.
- JAWS: Powerful but comes with a price tag.
- VoiceOver: If you’re on macOS or iOS, this one’s built right in.
- TalkBack: Google’s answer for Android devices.
But here’s the catch: screen readers rely on your site’s structure to do their job. If your code is messy or unclear, these tools might get confused, and that’s frustrating for users.
Making Your App More Accessible
Structure Your Content with Semantic HTML
First things first—let’s talk HTML. Using semantic tags isn’t just good practice; it’s essential for screen readers. Tags like <header>, <main>, and <nav> help define what each section of your page is all about. It’s like giving screen readers a map to navigate your site.
Instead of just slapping <div>s everywhere, try this:
<header>
<h1>Welcome to Our Website</h1>
</header>
<main>
<article>
<h2>Latest Updates</h2>
<p>Stay informed with our latest news.</p>
</article>
</main>
See the difference? It’s cleaner, easier to follow, and way more accessible.
Describe Images with Alt Text
Images are great, but if someone can’t see them, they’re just empty space—unless you add alt text. This text tells users what the image is about.
For example:
<img src="team.jpg" alt="A group of smiling coworkers in an office setting." />
It’s simple but powerful. Just don’t go overboard—no need to write "Image of..." at the start. And if an image is purely decorative, you can skip the description with alt="".
Make Sure the Keyboard Works
Not everyone uses a mouse, especially visually impaired users. So, your app needs to be fully functional with just a keyboard. That means:
- Ensuring users can navigate with the
Tabkey. - Making sure forms and modals respond to
Enterand arrow keys.
Pro tip: Test it yourself by putting your mouse away for a bit. You’ll quickly see where the pain points are.
Bring in ARIA Roles (When Needed)
Sometimes HTML alone doesn’t cut it, and that’s where ARIA (Accessible Rich Internet Applications) roles come in. They add extra information for screen readers.
For instance:
<button aria-label="Submit form">Submit</button>
This tells the screen reader exactly what the button does. But be careful—don’t overuse ARIA. If native HTML can do the job, stick with that.
Think About Contrast
Ever tried reading light gray text on a white background? It’s tough, even for people with perfect vision. Contrast is key. The WCAG recommends a contrast ratio of at least 4.5:1 for body text.
There are great tools like WebAIM Contrast Checker to help you nail this.
Forms Should Be Friendly
Forms are a minefield for accessibility, but they don’t have to be. Use clear labels, like this:
<label for="email">Email Address:</label>
<input id="email" type="email" required />
<small id="email-error" class="error">Please enter a valid email address.</small>
And make sure error messages are descriptive—"Invalid input" doesn’t cut it.
Test with Real Tools
Finally, put yourself in your users’ shoes. Fire up a screen reader and see how your site feels. It’s one of the best ways to catch issues you might not notice otherwise.
Let’s Build a More Inclusive Web
Accessibility isn’t just a feature—it’s a mindset. By taking these steps, you’re not only helping visually impaired users but also making your app better for everyone. It’s about creating a web where no one is left out. And honestly, isn’t that what good design is all about?

It’s going to be tough, but go read, understand, read again and master the concepts of what WCAG guidelines expose. It’s not an easy read and you will go back a thousand times to relearn stuff, but in the long term it will make sense and you’ll master the concepts, the ideas behind the terms “perceivable”, “operable” and so on. And then you will start thinking with accessibility first naturally. It is not something to apply “later on in another iteration or sprint”. We need to change our mindsets. Good to know there’s people considering it ❤️
This needs to be a much bigger discussion in the tech industry.
The section about keyboard accessibility and the tip of putting away the mouse to find pain points is genuis, really. (despite me being on mobile)
Accessibility in my project is something I've personally took very seriously by ensuring these technologies you've mentioned are capable of truly Aiding the users and not working against them.
In my opinion, there are too many sites and apps out there that simply don't cater to it or don't do it well.
Great read and the topic deserves more attention then it has.😁👍
very informative
