CSS CSS Flexbox Layout Flexbox Properties Growing and Aligning Flex Items

CSS Flex: Not sure why this is wrong

Question says: "Select the class .column and use the flex item property and value that will expand the columns to fill the space of the row."

I tried the below and it says wrong, "Use the property that determines how much of the available space a flex item should take up."

This works when I test it on an outside browser. What's wrong about it?

/* Complete the challenge by writing CSS below */

.row {
  display: flex;

.column {
  flex: 1;
<!DOCTYPE html>
    <title>Flexbox Layout</title>
    <link href='https://fonts.googleapis.com/css?family=Varela+Round' rel='stylesheet' type='text/css'>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
    <div class="row">   
      <div class="secondary column">
        <h2>How to get here</h2>
        <p>Tiramisu caramels gummies chupa.</p>

      <div class="primary column">
        <p>Everything in this city is worth waiting in line for.</p>
        <img src="treats.svg" alt="treats">

      <div class="tertiary column">
        <h2>Great food</h2>
        <p>Croissant macaroon pie brownie.</p>

flex is shorthand for 3 properties: flex-grow, flex-shrink, and flex-basis. I believe the code challenge you're on is looking for one of those properties specifically, even though what you've written works in practice. So, just be a little more specific instead of just saying flex and it should work.

That was it. Thank you!

You're just missing a word here ... and a hyphen. This is what it's expecting:

.column {
  flex-grow: 1;

Thank you too!

Try with -webkit- in front of flex-wrap. Maybe the challenge was created before the full browser compatibility.

No, that's not working for me. But I appreciate the assistance!
