bad87fee1348bd9aedf08719	Use Abbreviated Hex Code	0	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: Give your <code>h1</code> element with the text <code>I am red!</code> the <code>color</code> red.
    testString: assert($('.red-text').css('color') === 'rgb(255, 0, 0)');
  - text: Use the abbreviate <code>hex code</code> for the color red instead of the hex code <code>#FF0000</code>.
    testString: assert(code.match(/\.red-text\s*?{\s*?color:\s*?#F00\s*?;\s*?}/gi));
  - text: Give your <code>h1</code> element with the text <code>I am green!</code> the <code>color</code> green.
    testString: assert($('.green-text').css('color') === 'rgb(0, 255, 0)');
  - text: Use the abbreviated <code>hex code</code> for the color green instead of the hex code <code>#00FF00</code>.
    testString: assert(code.match(/\.green-text\s*?{\s*?color:\s*?#0F0\s*?;\s*?}/gi));
  - text: Give your <code>h1</code> element with the text <code>I am cyan!</code> the <code>color</code> cyan.
    testString: assert($('.cyan-text').css('color') === 'rgb(0, 255, 255)');
  - text: Use the abbreviated <code>hex code</code> for the color cyan instead of the hex code <code>#00FFFF</code>.
    testString: assert(code.match(/\.cyan-text\s*?{\s*?color:\s*?#0FF\s*?;\s*?}/gi));
  - text: Give your <code>h1</code> element with the text <code>I am fuchsia!</code> the <code>color</code> fuchsia.
    testString: assert($('.fuchsia-text').css('color') === 'rgb(255, 0, 255)');
  - text: Use the abbreviated <code>hex code</code> for the color fuchsia instead of the hex code <code>#FF00FF</code>.
    testString: assert(code.match(/\.fuchsia-text\s*?{\s*?color:\s*?#F0F\s*?;\s*?}/gi));
