💦 jQuery Selectors

      👦The element Selector

              You can select all <p> elements on a page like this:

$("p") 

 

 

    👦The  #id selector

      An id should be unique within a page, so you should use the #id selector when you want to find a single, unique element.

$("#test") 

 

     👦 The . class selector

     To find elements with a specific class, write a period character, followed by the name of the class:

$(".test")
