CSS CSS Flexbox Layout Flexbox Properties Flexbox Properties Review

Which of the following rules will display the layout shown in the image?

I have tried answering it multiple times but I can never seem to get the correct answer. The options are as follows:

.col { flex: 150%; }

.col { flex: 100px; }

.col { flex: 1; }

Does it have to do with the % vs px? Why can't I find the right answer?

This is the right answer col { flex: 1; } If an element has flex: 1, this means the size of all of the other elements will have the same width as their content. All .col will have the same width.

A single value given to the "flex" shorthand is assumed to be a setting for "flex-basis" if it has any unit, and for "flex-grow" if just a number.

Hint: The correct answer is a unitless value that causes each column to take up the same amount of space relative to the others.

Thank you for your help
