## Description
|
|
<section id='description'>
|
|
There is a shortcut available to set several flex properties at once. The <code>flex-grow</code>, <code>flex-shrink</code>, and <code>flex-basis</code> properties can all be set together by using the <code>flex</code> property.
|
|
For example, <code>flex: 1 0 10px;</code> will set the item to <code>flex-grow: 1;</code>, <code>flex-shrink: 0;</code>, and <code>flex-basis: 10px;</code>.
|
|
The default property settings are <code>flex: 0 1 auto;</code>.

## Instructions
|
|
<section id='instructions'>
|
|
Add the CSS property <code>flex</code> to both <code>#box-1</code> and <code>#box-2</code>. Give <code>#box-1</code> the values so its <code>flex-grow</code> is 2, its <code>flex-shrink</code> is 2, and its <code>flex-basis</code> is 150px. Give <code>#box-2</code> the values so its <code>flex-grow</code> is 1, its <code>flex-shrink</code> is 1, and its <code>flex-basis</code> is 150px.
|
|
These values will cause <code>#box-1</code> to grow to fill the extra space at twice the rate of <code>#box-2</code> when the container is greater than 300px and shrink at twice the rate of <code>#box-2</code> when the container is less than 300px. 300px is the combined size of the <code>flex-basis</code> values of the two boxes.

|
|
- text: The <code>#box-1</code> element should have the <code>flex</code> property set to a value of 2 2 150px.
|
|
testString: assert($('#box-1').css('flex-grow') == '2' && $('#box-1').css('flex-shrink') == '2' && $('#box-1').css('flex-basis') == '150px');
|
|
- text: The <code>#box-2</code> element should have the <code>flex</code> property set to a value of 1 1 150px.
|
|
testString: assert($('#box-2').css('flex-grow') == '1' && $('#box-2').css('flex-shrink') == '1' && $('#box-2').css('flex-basis') == '150px');
|
|
- text: Your code should use the <code>flex</code> property for <code>#box-1</code> and <code>#box-2</code>.
|
|
testString: assert(code.match(/flex:\s*?\d\s+?\d\s+?150px;/g).length == 2);
