Description

You can also target elements by their id attributes. First target your button element with the id target3 by using the $("#target3") selector. Note that, just like with CSS declarations, you type a # before the id's name. Then use jQuery's .addClass() function to add the classes animated and fadeOut. Here's how you'd make the button element with the id target6 fade out: $("#target6").addClass("animated fadeOut").

Instructions

Tests

tests:
  - text: 'Select the <code>button</code> element with the <code>id</code> of <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class of <code>animated</code>.'
    testString: 'assert($("#target3").hasClass("animated"), "Select the <code>button</code> element with the <code>id</code> of <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class of <code>animated</code>.");'
  - text: 'Target the element with the id <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class <code>fadeOut</code>.'
    testString: 'assert(($("#target3").hasClass("fadeOut") || $("#target3").hasClass("fadeout"))  && code.match(/\$\(\s*.#target3.\s*\)/g), "Target the element with the id <code>target3</code> and use the jQuery <code>addClass&#40&#41</code> function to give it the class <code>fadeOut</code>.");'
  - text: Only use jQuery to add these classes to the element.
    testString: 'assert(!code.match(/class.*animated/g), "Only use jQuery to add these classes to the element.");'
