Web Accessibility: Where to Start as a Beginner (2025 Guide)

“But… where do I even start if I want to make my website accessible?”

If that question keeps running through your mind, do not worry. You are not alone. And most importantly: you are already moving in the right direction.

Millions of people live with disabilities, and many websites still create unnecessary barriers for them.

It is frustrating. It is unfair.

But most importantly… many accessibility problems can start being fixed today.

And guess what? You do not need to be an expert developer or designer. You do not even need a huge budget. You mainly need the willingness to make a difference.

So if you want to learn independently, improve step by step, and become a more inclusive developer or creator, this article is for you.

Web accessibility is not a gimmick. It is not just an administrative requirement either. It is about people.

Imagine this:

• You are blind and want to order medication online… but the image used for the “Buy” button has no meaningful alternative text. Your screen reader announces only: “image”. Nothing else. You are stuck.
• You have limited motor control and cannot use a mouse. But the navigation menu does not work with a keyboard. You cannot continue.
• You have dyslexia, and the website uses tightly packed text on a bright background. Reading becomes exhausting, so you leave.

👉 Situations like these happen every day.

But they do not have to.

Accessibility means opening the door to everyone, not only to the “perfect users” we sometimes imagine when designing a website.

And the good news is that everyone can contribute, even when learning independently.

You may have heard about WCAG. These are international guidelines for making web content more accessible. Behind the acronyms are four simple principles, commonly summarized as POUR:

1. Perceivable

People need to be able to perceive the information, regardless of how they access it.

Example: Someone with low vision may need sufficient contrast between text and its background. A deaf or hard-of-hearing person may need captions for video content.

2. Operable

The website should be usable through different input methods: mouse, keyboard, voice control, and assistive technologies.

Human tip: Try using your website without a mouse for five minutes. If you get stuck, some users probably will too.

3. Understandable

Content and interactions should be clear, consistent, and understandable.

A useful question: “Would someone unfamiliar with this website understand what to do next?” If not, simplify it.

4. Robust

The website should work reliably across browsers, devices, and assistive technologies.

You do not need to be an expert: Start with clean, semantic HTML. That already gives you a strong foundation.

Want something practical? Here are five common accessibility mistakes — and simple ways to improve them:

Problem: Low-contrast text

Why it matters: It can be difficult or impossible to read for people with low vision.

Simple solution: Use a contrast checker such as WebAIM’s contrast tool.

Problem: Images without useful alt text

Why it matters: A screen reader may not be able to communicate the image’s purpose or meaning.

Simple solution: Add appropriate alternative text when the image conveys information. Example: alt="Marie smiling in front of her computer"

Problem: Poor heading structure — for example jumping between heading levels without a logical hierarchy

Why it matters: The content structure can become difficult to understand, especially for people navigating by headings with assistive technology.

Simple solution: Use headings to represent the actual hierarchy of your content: <h1>, <h2>, <h3>, and so on.

Problem: Vague links such as “click here”

Why it matters: When links are read out of context, labels such as “click here” do not explain where they lead.

Simple solution: Make the link text meaningful. For example: “Download the free accessibility guide” instead of “click here”.

Problem: Navigation that only works with a mouse

Why it matters: Some people cannot use a mouse because of motor impairments, injuries, or their choice of assistive technology.

Simple solution: Test your website using the Tab key. Can you reach and activate all interactive controls? If not, review focus behavior and keyboard interactions.

You do not need to rebuild your entire website. Start small. Make steady progress.

1. Run a Quick Accessibility Audit

Use one of these tools:

• Google Lighthouse in Chrome → provides automated accessibility checks
• WAVE → highlights many accessibility issues visually
• axe DevTools → provides automated accessibility testing inside the browser

Friendly advice: Run Lighthouse on your homepage. If the score is lower than you expected, do not treat it as a punishment. Treat it as a starting point — and remember that automated tools cannot detect every accessibility problem.

2. Fix the Basics

Choose one thing to improve:

• Add appropriate alt text to important informative images.
• Adjust text and background colors so they meet appropriate contrast requirements.
• Replace “click here” with descriptive text such as “Read the complete accessibility guide”.

👉 One improvement at a time can make the web more inclusive.

3. Test with the Keyboard

Put your mouse aside.

Use the Tab key, Shift+Tab, Enter, Space, and other expected keyboard controls.

Can you:

• Move between links and controls?
• Open and operate a menu?
• Complete and submit a form?

If not, you have found a real usability problem worth fixing.

4. Use Semantic HTML — Even as a Beginner

It sounds technical, but the idea is simple.

Instead of:

<div class="header">My website</div>

Use:

<header>My website</header>

And instead of:

<div class="nav">...</div>

Use:

<nav>...</nav>

✅ Why? Semantic elements provide useful structure to browsers and assistive technologies. Think of them like signs in a city: they help people understand where they are.

Want to go further? Here are several useful resources:

• Access42 — A French-language accessibility resource with practical guidance.
• Digital accessibility courses and MOOCs — useful for structured self-learning.
• The A11y Project — An international community with practical accessibility examples. “A11y” is shorthand for “accessibility”.
• Opquast — Web quality best practices, including accessibility-related practices.
• W3C WCAG — The official accessibility guidelines. Read them gradually rather than trying to absorb everything at once.

You do not need to learn everything at once. Learn one useful concept at a time and apply it to a real project. 

Web accessibility is not magic, and it is not reserved for experts.

It is a human-centered practice built through repeated improvements.

You do not need:

• A degree
• A huge budget
• An entire month

You mainly need to:

✅ Start

✅ Fix one problem

✅ Repeat

And each time, you make the web a little more open and inclusive.

You already have one of the most important tools: the willingness to do better.

So here is your mission:

👉 Open your website or project.

👉 Run Lighthouse, WAVE, or another accessibility testing tool.

👉 Find one issue.

👉 Fix it.

You do not need to be perfect.

You do not need to wait.

An inclusive web is built step by step. And you can already contribute to it.

So?

What will you improve first?
