bad87fee1348bd9aedf08719	Use Abbreviated Hex Code	0	false	https://scrimba.com/c/cRkpKAm	18338

Description

Many people feel overwhelmed by the possibilities of more than 16 million colors. And it's difficult to remember hex code. Fortunately, you can shorten it. For example, red's hex code #FF0000 can be shortened to #F00. This shortened form gives one digit for red, one digit for green, and one digit for blue. This reduces the total number of possible colors to around 4,000. But browsers will interpret #FF0000 and #F00 as exactly the same color.

Instructions

Go ahead, try using the abbreviated hex codes to color the correct elements.

Color	Short Hex Code
Cyan	#0FF
Green	#0F0
Red	#F00
Fuchsia	#F0F

Tests

tests:
  - text: Your <code>h1</code> element with the text <code>I am red!</code> should be given the <code>color</code> red.
    testString: assert($('.red-text').css('color') === 'rgb(255, 0, 0)');
  - text: The abbreviated <code>hex code</code> for the color red should be used instead of the hex code <code>#FF0000</code>.
    testString: assert(code.match(/\.red-text\s*?{\s*?color:\s*?#F00\s*?;\s*?}/gi));
  - text: Your <code>h1</code> element with the text <code>I am green!</code> should be given the <code>color</code> green.
    testString: assert($('.green-text').css('color') === 'rgb(0, 255, 0)');
  - text: The abbreviated <code>hex code</code> for the color green should be used instead of the hex code <code>#00FF00</code>.
    testString: assert(code.match(/\.green-text\s*?{\s*?color:\s*?#0F0\s*?;\s*?}/gi));
  - text: Your <code>h1</code> element with the text <code>I am cyan!</code> should be given the <code>color</code> cyan.
    testString: assert($('.cyan-text').css('color') === 'rgb(0, 255, 255)');
  - text: The abbreviated <code>hex code</code> for the color cyan should be used instead of the hex code <code>#00FFFF</code>.
    testString: assert(code.match(/\.cyan-text\s*?{\s*?color:\s*?#0FF\s*?;\s*?}/gi));
  - text: Your <code>h1</code> element with the text <code>I am fuchsia!</code> should be given the <code>color</code> fuchsia.
