Логичный порядок Tab следует за содержимым

Press Tab and focus walks a fixed route through the page. That route is the tab order, and getting it right keeps users oriented. 🧭

By default tab order matches your source order, the top-to-bottom sequence of elements in the HTML, not what you see on screen.

Aim for focus to move in the same order people read the page. Header first, then main content, then footer feels natural.

Layout tools like flexbox order move boxes visually but leave the DOM untouched. Focus still follows source, so the two can disagree.

When CSS reorders items, a keyboard user can jump backward and forward unexpectedly. The fix is to align your HTML order with the visual one.

A positive tabindex like 3 forces a control to the front of the order. It almost always creates a confusing, hard-to-maintain mess.

Instead of patching with tabindex, just put elements in the right order in the markup. Clean source order needs no special attributes.

An element with display none leaves the tab order entirely. Show it again and it quietly returns to its DOM position.

When JavaScript injects new controls, they land wherever you append them. Insert in a sensible spot so the order stays logical.

A dialog appended at the page end can leave focus stranded far away. Good focus management sends users into the modal on open.

The proof is simple. Tab from the top and confirm focus moves in a sensible order with no surprising leaps around the screen.

Decide what really drives the default tab order.

Keep focus moving the way people read. Match source order to the visual layout, avoid positive tabindex, and Tab-test the result. ✅
