--description--

We can also change the CSS of an HTML element directly with jQuery.

jQuery has a function called .css() that allows you to change the CSS of an element.

Here's how we would change its color to blue:

$("#target1").css("color", "blue");

This is slightly different from a normal CSS declaration, because the CSS property and its value are in quotes, and separated with a comma instead of a colon.

Delete your jQuery selectors, leaving an empty document ready function.

Select target1 and change its color to red.

--hints--

Your target1 element should have red text.

assert($('#target1').css('color') === 'rgb(255, 0, 0)');

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

assert(!code.match(/class.*animated/g));
