Universal (*) Selector
In jQuery, selectors are a parameter through which we can select the HTML element. Selectors can comprise – class names, ids, tag names, attributes, etc. Basically, by using selectors, the appropriate HTML-DOM element can be selected and hence performed actions on it. Here, we are discussing the jQuery * Selector.
The jQuery * selector selects every element present on the DOM page. It includes – HTML elements, head, body, etc. When just the * passes, it selects overall elements, but when it is used with some other element, then it selects all the elements within that domain.
Universal (*) Selector Syntax
$('*');
Once the elements are selected, you can access those and perform the actions that you want to perform on them. The example given below shows the selection of all the elements present in the parent div tag. Once selected, they are faded out on click.
