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