587d78ae367417b2b2512afe	Use the flex Shorthand Property	0	https://scrimba.com/p/pVaDAv/cbpW2tE	301112

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

tests:
  - text: The <code>#box-1</code> element should have the <code>flex</code> property set to a value of <code>2 2 150px</code>.
    testString: assert($('#box-1').css('flex-grow') == '2' && $('#box-1').css('flex-shrink') == '2' && $('#box-1').css('flex-basis') == '150px');
  - text: The <code>#box-2</code> element should have the <code>flex</code> property set to a value of <code>1 1 150px</code>.
    testString: assert($('#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);
