Universal Selector
A universal selector is a selector that matches any element type’s name instead of selecting elements of a particular type. The universal selector becomes helpful when you wish to put a specific style in all the HTML elements within your web page
syntax
* {
property : value;
}uses the asterisk (“*”) symbol used for denoting the selector as a universal selector. It is usually written as an asterisk followed by a selector. The * is used for selecting all elements. This asterisk also has the capability to select all elements that are inside another element.
example
* {
margin : 0px;
padding : 0px;
}There are some additional properties of Universal selector, where you can make use of a combination of asterisk with namespace:

- |* – this will allow you to match all elements that are without any declared namespace.
