When making websites, you must think about web standards, semantic code, and accessibility, and how these are related. Web standards are like rules everyone agrees to follow to ensure websites work well for everyone. Semantic code is writing code in a way that makes sense not just to computers but also to people. Accessibility is about ensuring everyone, including people with disabilities, can use and understand our websites.
Web standards also help us create websites that are more accessible to everyone. Semantic code makes it easier for people and search engines to understand what our websites are about, which can improve accessibility and search engine rankings. Making websites accessible means considering things like screen readers for people who are blind or have low vision, keyboard navigation for people who can't use a mouse, and captions for videos for people who are deaf or hard of hearing.
From a legal and ethical perspective, an accessible website is very important because it gives equal access to information for everyone. It's not just the right thing to do, it's also required by laws like the Americans with Disabilities Act (ADA).
