--description--

Every HTML element has a parent element from which it inherits properties.

For example, the h3 element in your jQuery Playground has the parent element of <div class="container-fluid">, which itself has the parent element of body.

jQuery has a function called parent() that allows you to access the parent of whichever element you've selected.

Here's an example of how you would use the parent() function if you wanted to give the parent element of the left-well element a background color of blue:

$("#left-well").parent().css("background-color", "blue")

Give the parent of the #target1 element a background-color of red.

--hints--

Your left-well element should have a red background.

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'
);

You should use the .parent() function to modify this element.

assert(code.match(/\.parent\s*\(\s*\)\s*\.css/g));

The .parent() method should be called on the #target1 element.

assert(
  code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")\s*?\)\s*?\.parent/gi)
);

You should only use jQuery to add these classes to the element.

assert(code.match(/<div class="well" id="left-well">/g));
