Target HTML Elements with Selectors Using jQuery

• jQuery selectors allow you to select and manipulate HTML elements.
• These selectors start with the dollar sign and parentheses: $()
• You can "find" (or select) HTML elements based on their name, id, classes, types, attributes, values of attributes and much more.

Example

//You can select all <p> elements on a page like this  =  $("p")
$(document).ready(function(){
  $("button").click(function(){
    $("p").hide();
  });
});

Solution

<script>
  $(document).ready(function(){
    $("button").addClass("animated bounce");
  });
</script>
