Imagine you're reading a book, but the words are so tiny you can't see them, or the pages are blank. That wouldn't be very helpful, right? The same goes for websites. The idea of "perceivable" means that all the important stuff on a website, like text, pictures, and buttons, needs to be clear and easy for everyone to see or hear. This includes people who might have trouble seeing or hearing.
What Does This Mean?
- Text You Can See: The words on the website should be big enough and in colors that are easy to read.
- Pictures You Can Understand: If there's a picture, there should be a way to describe it for people who can't see it. This could be a small piece of text called "alt text" that tells what the picture shows.
- Sounds You Can Hear: If there's sound, like a video, it should have captions so that people who can't hear can read what is being said.
Simple Code Example
Let's say you have a picture of a dog on your website. You need to make sure that people who can't see the picture still know it's a dog. Here's how you can do that with code:
<img src="dog.jpg" alt="A cute brown dog playing in the park">In this example, the alt="A cute brown dog playing in the park" part is the description that helps people understand the picture even if they can't see it.
Why Is This Important?
When everything on a website is easy to see, hear, or understand, it means more people can use it, no matter what challenges they might have. Whether someone can't see well, can't hear well, or needs extra help understanding, the website should be welcoming and usable for everyone.
