so here, I prioritized the search and submit inputs with tabindex as 1 and 2 respectively.
shouldn’t this enable me to focus on them via tab before the three links (home, blog, training)?

i understand that links among some element types are automatically given keyaccess, but aren’t they still a part of the source code order, which should be overridden by positive tab index values?

thanks in advance!!!

Ah! So with the code I provided, what happened was this:
When I tried tabbing through the page, the selector focused on the three anchor elements (in the order they are written) before focusing on the two input elements to which I had given priority with positive tabindex values (1 and 2).

If my question still isn’t clear, then perhaps my understanding of the function of positive tabindex values is incorrect…
