Digital accessibility: five barriers many sites ignore
Small design and code details decide whether a person can or cannot use a website.

When people talk about digital accessibility, many think of something rare. In fact, it affects people with visual, hearing, motor or cognitive disabilities, but also someone with an injured hand, outside in strong sun or on a slow connection. An accessible site is, in general, a better site for everyone.
Why it matters
About one in six people in the world has some form of disability, according to World Health Organization estimates. A site that ignores these people excludes a significant part of the audience and, in many countries, may have legal obligations. To learn more, there are international web content accessibility guidelines, known as WCAG.
Five common barriers
1. Missing alternative text on images
People who use screen readers depend on a description to understand an image. Without it, the reader only says "image" or reads the file name. What to do: briefly describe what the image conveys.
2. Insufficient contrast
Light gray text on a white background is hard for many people to read. What to do: use colors with adequate contrast between text and background.
3. Keyboard navigation that is impossible
Some people do not use a mouse. If menus and buttons only work with the mouse, they are blocked. What to do: make sure everything can be reached and triggered with the Tab and Enter keys, with a visible focus indicator.
4. Forms without clear labels
Fields with no label, or that rely only on color to indicate an error, confuse screen readers and people with color blindness. What to do: associate each field with a label and explain errors in text.
5. Videos and audio without alternatives
Without captions, deaf people or those in silent environments miss the content. What to do: offer captions and, when possible, a transcript.
An example
A small online store received complaints from a customer who used a screen reader and could not complete the purchase: the "Checkout" button was an image with no description. After adding alternative text and a clear label, the problem was solved, and other customers also reported that navigation felt clearer. This is an illustrative example.
Putting it into practice
You can run a simple test on any site: try navigating using only the Tab key, increase your browser's font size and see whether the text remains readable. If something breaks, there is a barrier.
Conclusion
Accessibility is not an extra feature: it is part of a site's quality. Starting with a few fixes already makes a difference, and every barrier removed opens the door to more people.
