# --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.
|
|
|
|
<table class='table table-striped'><tbody><tr><th>Color</th><th>Short Hex Code</th></tr><tr><td>Cyan</td><td><code>#0FF</code></td></tr><tr><td>Green</td><td><code>#0F0</code></td></tr><tr><td>Red</td><td><code>#F00</code></td></tr><tr><td>Fuchsia</td><td><code>#F0F</code></td></tr></tbody></table>

# --hints--
|
|
|
|
Your `h1` element with the text `I am red!` should be given the `color` red.
|
|
|
|
```js
|
|
assert($('.red-text').css('color') === 'rgb(255, 0, 0)');
|
|
```
|
|
|
|
The abbreviated `hex code` for the color red should be used instead of the hex code `#FF0000`.
|
|
|
|
```js
|
|
assert(code.match(/\.red-text\s*?{\s*?color:\s*?#F00\s*?;\s*?}/gi));
|
|
```
|
|
|
|
Your `h1` element with the text `I am green!` should be given the `color` green.
|
|
|
|
```js
|
|
assert($('.green-text').css('color') === 'rgb(0, 255, 0)');
|
|
```
|
|
|
|
The abbreviated `hex code` for the color green should be used instead of the hex code `#00FF00`.
|
|
|
|
```js
|
|
assert(code.match(/\.green-text\s*?{\s*?color:\s*?#0F0\s*?;\s*?}/gi));
|
|
```
|
|
|
|
Your `h1` element with the text `I am cyan!` should be given the `color` cyan.
|
|
|
|
```js
|
|
assert($('.cyan-text').css('color') === 'rgb(0, 255, 255)');
|
|
```
|
|
|
|
The abbreviated `hex code` for the color cyan should be used instead of the hex code `#00FFFF`.
|
|
|
|
```js
|
|
assert(code.match(/\.cyan-text\s*?{\s*?color:\s*?#0FF\s*?;\s*?}/gi));
|
|
```
|
|
|
|
Your `h1` element with the text `I am fuchsia!` should be given the `color` fuchsia.
|
|
|
|
```js
|
|
assert($('.fuchsia-text').css('color') === 'rgb(255, 0, 255)');
|
|
```
|
|
|
|
The abbreviated `hex code` for the color fuchsia should be used instead of the hex code `#FF00FF`.
|
|
|
|
```js
|
|
assert(code.match(/\.fuchsia-text\s*?{\s*?color:\s*?#F0F\s*?;\s*?}/gi));
|
|
```
