Why Accessibility in HTML Isn’t Just a Buzzword
Pull up a chair. Let’s chat about something that’s been on my mind for a while—accessibility in HTML. It’s not just about checking a box or ticking off a compliance list. Nope. It’s about real people, navigating the web with all sorts of tools and challenges. When we get accessibility right, it’s like handing a map to someone who otherwise might wander in circles.
But here’s the kicker: even seasoned developers slip up. I’ve been there. The good news? Most mistakes are easy to spot and fix once you know what to look for. So, let’s dive into some of the most common accessibility mistakes in HTML and, more importantly, how to fix them. Ready?
1. Skipping Semantic HTML—The Backbone You Didn’t Know You Needed
Ever landed on a page and felt like you were thrown into the deep end with no life jacket? That’s what happens when semantic HTML is ignored. Using generic <div> and <span> tags everywhere might look neat in your code editor, but it’s a nightmare for assistive tech. Screen readers rely heavily on semantic tags to understand structure and navigation.
Think of semantic tags as signposts: <header> tells users “Hey, this is the top,” <nav> says “Here’s where you find links,” and <main> points to the core content. Without them, users can get lost quickly.
How to Fix It: Audit your markup. Swap generic containers for meaningful tags. Use <article>, <section>, and <footer> appropriately. Not only does this help screen readers, but it also improves SEO—win-win.
2. Missing or Misused Alt Attributes on Images
Here’s a classic: images without alt text or with alt text like “image123” or worse, empty alt on informative images. It’s like describing a painting as “picture” to a blind visitor—useless. Alt attributes are your chance to narrate the image’s purpose.
But be cautious. Sometimes, decorative images don’t need alt text, and adding verbose descriptions can clutter screen reader output. It’s about intent.
How to Fix It: For meaningful images, add concise, descriptive alt text. For purely decorative images, use alt="" to skip them gracefully. Tools like WAVE can help you spot missing alt attributes fast.
3. Overlooking Keyboard Navigation
Accessibility isn’t just about vision. Many users rely on keyboards alone to browse. If your site traps keyboard focus or skips vital controls, it’s like building a door with no handle.
I remember debugging a client’s modal dialog that completely broke keyboard flow. Users could get stuck inside or lose focus on closing buttons. Frustrating as hell.
How to Fix It: Make sure all interactive elements are reachable via Tab. Avoid tabindex values that mess with natural flow except for very specific cases. Test with keyboard only—no mouse allowed! Tools like the aXe browser extension are lifesavers here.
4. Using Color Alone to Convey Information
“Click the red button to delete.” Sounds simple, right? But for folks with color blindness, that instruction might as well be a riddle. Relying solely on color excludes a chunk of your audience.
Color is fantastic for emphasis, but never the only signal.
How to Fix It: Combine color with text, icons, patterns, or shapes. For example, instead of just a red border for errors, include an error icon or text label. Run your palette through simulators like Color Oracle to catch potential issues.
5. Poorly Structured Headings
Headings are like a table of contents for your page. When they’re out of order or skipped—say going from <h1> straight to <h4>—screen readers get confused. It’s like reading a book with random chapter numbers.
One time, I saw a site where the entire main content was wrapped in an <h6>. No idea what the intention was, but it made navigating a nightmare.
How to Fix It: Use headings sequentially. Start with <h1>, then <h2>, and so on. Don’t jump levels. It helps users and search engines alike.
6. Ignoring ARIA Roles and Attributes (Or Using Them Incorrectly)
ARIA (Accessible Rich Internet Applications) attributes are powerful but can also be dangerous if misused. They’re not a fix-all for bad HTML. I see folks slap role="button" on a <div> without keyboard event handlers or focusability. That’s like putting a steering wheel on a shopping cart.
How to Fix It: First, prefer native HTML elements because they come with built-in accessibility. Use ARIA when you’re building custom widgets or complex interactions. And, critically, test with screen readers to ensure your ARIA roles do what they’re supposed to.
7. Neglecting Form Labels and Instructions
Forms are often where accessibility really trips up. Missing <label> tags, unclear instructions, or confusing error messages can turn a simple sign-up into a frustrating maze.
Imagine trying to fill out a form and not knowing what each field means. Been there, felt that.
How to Fix It: Always associate labels with inputs using the for attribute or by wrapping inputs inside labels. Provide clear instructions and error messages that screen readers can announce. The aria-describedby attribute is handy for linking extra info.
8. Forgetting to Test with Real Users and Tools
Here’s the thing: no checklist or automated tool can catch everything. I learned this the hard way when I relied solely on automated audits. They’re great for catching low-hanging fruit but miss the nuance.
The real magic happens when you combine tools with manual testing—keyboard navigation, screen readers like NVDA or VoiceOver, and, best of all, feedback from users with disabilities.
How to Fix It: Build testing into your process. Use tools like axe, WAVE, and Lighthouse. But don’t stop there. Try navigating your site blindfolded (figuratively) or with keyboard only. Ask actual users for feedback whenever possible.
Wrapping Up: Accessibility Is a Journey, Not a Destination
Accessibility can feel overwhelming. Trust me, I’ve been down that rabbit hole more than once. But every little fix you make brings the web closer to being a place everyone can enjoy, regardless of ability.
So, what’s your next move? Maybe take a second look at your last project. Scan for these common mistakes. Fix a few. And keep going. Because that’s how progress happens—one honest, imperfect step at a time.
Got questions or want to share your own accessibility wins and fails? I’m all ears. Let’s keep this conversation going, for all the folks who need the web to work for them.
