jQuery | element Selector

jQuery element selector is used to select and modify HTML elements based on the element name.

Syntax:

$("element_name")

Example-1: This example selects the “h2” element and adds border to it.

<!DOCTYPE html> 
<html> 
  
<head> 
  
    <script src= 
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"> 
  </script> 
  
     
  <script> 
    $(document).ready(function() { 
     $("h2").css("border",  
                 "5px solid green"); 
        }); 
    </script> 
  
</head> 
  
<body> 
  
    <h2>GeeksForGeeks
