--description--

The Complementary Colors challenge showed that opposite colors on the color wheel can make each other appear more vibrant when placed side-by-side. However, the strong visual contrast can be jarring if it's overused on a website, and can sometimes make text harder to read if it's placed on a complementary-colored background. In practice, one of the colors is usually dominant and the complement is used to bring visual attention to certain content on the page.

--instructions--

This page will use a shade of teal (#09A7A1) as the dominant color, and its orange (#FF790E) complement to visually highlight the sign-up buttons. Change the background-color of both the header and footer from black to the teal color. Then change the h2 text color to teal as well. Finally, change the background-color of the button to the orange color.

--hints--

The header element should have a background-color of #09A7A1.

assert($('header').css('background-color') == 'rgb(9, 167, 161)');

The footer element should have a background-color of #09A7A1.

assert($('footer').css('background-color') == 'rgb(9, 167, 161)');

The h2 element should have a color of #09A7A1.

assert($('h2').css('color') == 'rgb(9, 167, 161)');

The button element should have a background-color of #FF790E.

assert($('button').css('background-color') == 'rgb(255, 121, 14)');
