The English translation of toggle is switching, conversion, which refers to switching between two states.

The toggle() method is used to bind two or more event handler functions to respond to the click event of the selected element in turn.

The toggle() method switches between hide() and show() on the selected element.

This method checks the visible status of the selected element. If an element is hidden, show() is run, if an element is visible, hide() is run - this creates a toggle effect.

Note: Hidden elements will not be fully displayed (no longer affect the layout of the page).

Tip: This method can be used to switch between custom functions.
