# --description--
|
|
|
|
There is a shortcut available to set several flex properties at once. The `flex-grow`, `flex-shrink`, and `flex-basis` properties can all be set together by using the `flex` property.
|
|
|
|
For example, `flex: 1 0 10px;` will set the item to `flex-grow: 1;`, `flex-shrink: 0;`, and `flex-basis: 10px;`.
|
|
|
|
The default property settings are `flex: 0 1 auto;`.
|
|
|
|
# --instructions--
|
|
|
|
Add the CSS property `flex` to both `#box-1` and `#box-2`. Give `#box-1` the values so its `flex-grow` is `2`, its `flex-shrink` is `2`, and its `flex-basis` is `150px`. Give `#box-2` the values so its `flex-grow` is `1`, its `flex-shrink` is `1`, and its `flex-basis` is `150px`.
|
|
|
|
These values will cause `#box-1` to grow to fill the extra space at twice the rate of `#box-2` when the container is greater than 300px and shrink at twice the rate of `#box-2` when the container is less than 300px. 300px is the combined size of the `flex-basis` values of the two boxes.
|
|
|
|
# --hints--
|
|
|
|
The `#box-1` element should have the `flex` property set to a value of `2 2 150px`.
|
|
|
|
```js
|
|
assert(
|
|
$('#box-1').css('flex-grow') == '2' &&
|
|
$('#box-1').css('flex-shrink') == '2' &&
|
|
$('#box-1').css('flex-basis') == '150px'
|
|
);
|
|
```
|
|
|
|
The `#box-2` element should have the `flex` property set to a value of `1 1 150px`.
|
|
|
|
```js
|
|
assert(
|
|
$('#box-2').css('flex-grow') == '1' &&
|
|
$('#box-2').css('flex-shrink') == '1' &&
|
|
$('#box-2').css('flex-basis') == '150px'
|
|
);
|
|
```
|
|
|
|
Your code should use the `flex` property for `#box-1` and `#box-2`.
|
|
|
|
```js
|
|
assert(code.match(/flex:\s*?\d\s+?\d\s+?150px;/g).length == 2);
|
|
```
