Building accessible software is a mark of professional maturity. It shows you understand that your users have diverse needs and physical capabilities.
1The Power of Meaning
Semantic HTML isn't just about 'cleaning up' your code. It's about providing metadata that machines (like Google's crawler) and assistive devices (like Braille displays) can use to understand your application.
2Keyboard First
Can you use your entire app without a mouse? If not, it's not accessible. Mid-level developers prioritize 'Focus States' and 'Tab Order' as much as they do visual hover states.
3The ARIA Safety Net
The first rule of ARIA is: 'Don't use ARIA if you can use native HTML'. Only use it to describe complex interactions (like a custom dropdown or a modal) that don't have a native semantic equivalent.
