Keyboard order
Why it matters
tabindex values above 0 force elements to the front of the keyboard order, so focus jumps unpredictably around the page (WCAG 2.4.3).
How to fix it
- Use tabindex="0" to make an element focusable in its natural position, or -1 for programmatic focus.
- Fix the HTML order instead of overriding it.
