css - flex item with image child doesn't adjust its size properly

Question

I found this post, Flex item with image child doesn't adjust from its original width, which I initial thought had the answer, but it didn't, ... well partially it did, when a set height is used.

What I want and expect to happen here, is that the image matches the text element's height and then adjust its width while keeping its ratio.

This appears to work in Chrome, but not in Edge/IE/Firefox. Haven't been able to test Safari as I don't have an iOS device, so I would appreciate if someone can share how/if it work there.

This doesn't need to be a flexbox solution, though I expect a CSS one, meaning no script.

Edit

The given text's height could be dynamic, and based on its content, so the predefined 200px was simply to give it a height, JSFiddle demo, set height .

Answer 1

You should define the height at the .container level. Following CSS will work for all the browsers you mentioned above:

.container {
    display: inline-flex;
    height: 200px;
}

.img {
    height: 100%;
}
.img img {
    height:100%;
}

.text {
    background: lightblue;
}

.text-content {
    width: 200px;
}

UPDATE

I'll leave the old answer just in case but this seems to work codepen. I've tried with varying number of lines and text sizes.

.container {
  display: inline-flex;
}

.img img {
  height:100%;
}

.text {
  background: lightblue;
}
