To modify CSS properties of an element, jQuery provides a method called .css(). This method accepts an argument for a CSS property name, and a corresponding CSS value.

It’s syntax looks like:

$('.example-class').css('color', '#FFFFFF');

Let’s break the example above into two pieces:

• We call the .css() method on .example-class. The first argument is the CSS property we want to change. In this case, that’s 'color'.
• The second argument specifies the new value for the given property in the first argument. In this case, the .css() method changes the color of .example-class elements to '#FFFFFF'.

Notice, both of the inputs to the .css() method are strings.
