The properties and attributes associated with those elements are some of the most basic elements that can be manipulated in relation to DOM elements.
jQuery gives us the means to control the attributes of an element quickly and allows us access to that element to modify its properties as well.
The attr() can set an attribute value from the first element in the corresponding set or set attribute values in all matched items.
You can use the attr(name, value) method to set the named attribute on all elements of the wrapped set with the provided value.
Apply defined style sheets to every matching element that can utilize the addClass(classes) function. Multiple space-divided classes can be specified.
