Focusing and blurring of elements - Basic JavaScript Fast (72) | tabindex, focusin, focusout
We can control the focusing and blurring of DOM elements, even if they are not allowed to focus by default. The focus and blur events can be triggered by elements. Or, the focus and blur methods can be applied to elements.
If an element is not allowed to focus by default, we can assign a tab index to it, so that generally the elements with a smaller index can be focused first.
The ordinary focus and blur events cannot be used in event delegation because they do not bubble up. If event delegation is to be achieved, focusin and focusout events can be used instead.
