How do I wrap row items using CSS Flexbox?

Question

I'm fairly new to CSS Flexbox but I'm trying to create a horizontal card, where an image is on the left, and text/buttons are on the right. When the site is scaled down (for mobile use), the row items should wrap and the image should sit on top of the text. I've tried setting the wrap property to wrap but it wraps for large screens when it should only wrap for smaller screens. See code below:

* {
  margin: 0;
  padding: 0;
}

#box {
  padding: 20px;
}

img {
  width: 200px;
}

#outer-container {
  display: flex;
  flex-wrap: wrap;
  border: solid 1px;
  width: 70%;
  margin: auto;
}

#inner-container {
  border: solid 1px;
  display: flex;
  justify-content: space-between;
  flex-direction: column;
}

<div id="outer-container">
  <img src="https://icatcare.org/app/uploads/2018/07/Thinking-of-getting-a-cat.png" alt="cat">
  <div id="inner-container">
    <div>
      <h3>Heading</h3>
      <br>

      Other stuff
    </div>
  </div>
</div>

Should I attempt to use another approach (like Bootstrap's card layouts) or is there something obvious I'm missing?

Answer 1

Set a flex-basis to the text container to control when the wrap should happen.

Open the below on full screen and resize to see:

* {
  margin: 0;
  padding: 0;
}

#box {
  padding: 20px;
}

img {
  width: 200px;
}

#outer-container {
  display: flex;
  flex-wrap: wrap;
  border: solid 1px;
  width: 70%;
  margin: auto;
}

#inner-container {
  border: solid 1px;
  display: flex;
  justify-content: space-between;
  flex-direction: column;
  
  flex-basis:500px;
  flex-grow:1;
}

<div id="outer-container">
  <img src="https://icatcare.org/app/uploads/2018/07/Thinking-of-getting-a-cat.png" alt="cat">
  <div id="inner-container">
    <div>
      <h3>Heading</h3>
