## Description
The opposite of flex-shrink
is the flex-grow
property. Recall that flex-shrink
controls the size of the items when the container shrinks. The flex-grow
property controls the size of items when the parent container expands.
Using a similar example from the last challenge, if one item has a flex-grow
value of 1 and the other has a flex-grow
value of 3, the one with the value of 3 will grow three times as much as the other.
## Instructions
Add the CSS property flex-grow
to both #box-1
and #box-2
. Give #box-1
a value of 1 and #box-2
a value of 2.
## Tests
```yml
tests:
- text: The #box-1
element should have the flex-grow
property set to a value of 1.
testString: assert($('#box-1').css('flex-grow') == '1', 'The #box-1
element should have the flex-grow
property set to a value of 1.');
- text: The #box-2
element should have the flex-grow
property set to a value of 2.
testString: assert($('#box-2').css('flex-grow') == '2', 'The #box-2
element should have the flex-grow
property set to a value of 2.');
