title: Target the Parent of an Element Using jQuery
challengeType: 6
forumTopicId: 18321
---
## Description
<section id='description'>
Every HTML element has a <code>parent</code> element from which it <code>inherits</code> properties.
For example, your <code>jQuery Playground</code> <code>h3</code> element has the parent element of <code>&#60;div class="container-fluid"&#62</code>, which itself has the parent <code>body</code>.
jQuery has a function called <code>parent()</code> that allows you to access the parent of whichever element you've selected.
Here's an example of how you would use the <code>parent()</code> function if you wanted to give the parent element of the <code>left-well</code> element a background color of blue:
<code>$("#left-well").parent().css("background-color", "blue")</code>
Give the parent of the <code>#target1</code> element a background-color of red.

```yml
tests:
- text: Your <code>left-well</code> element should have a red background.
testString: assert($("#left-well").css("background-color") === 'red' || $("#left-well").css("background-color") === 'rgb(255, 0, 0)' || $("#left-well").css("background-color").toLowerCase() === '#ff0000' || $("#left-well").css("background-color").toLowerCase() === '#f00');
- text: You should use the <code>&#46;parent&#40;&#41;</code> function to modify this element.
testString: assert(code.match(/\.parent\s*\(\s*\)\s*\.css/g));
- text: The <code>&#46;parent&#40;&#41;</code> method should be called on the <code>&#35;target1</code> element.
testString: assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")\s*?\)\s*?\.parent/gi));
- text: You should only use jQuery to add these classes to the element.
testString: assert(code.match(/<div class="well" id="left-well">/g));
