## Description
|
|
<section id='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 <code>#FF0000</code> can be shortened to <code>#F00</code>. 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 <code>#FF0000</code> and <code>#F00</code> as exactly the same color.

|
|
- 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)');

|
|
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>.
|
|
