Inline block in Firefox does not scale down to contents

Question

I have two columns, both 50% of the screen-width. The left column is filled with text, the right column has an image that scales to the height of the text. Another image is placed over this first image, positioned in the bottom right corner. Even if the screen-width exceeds the image-width (and whitespace appears to the right of the image), the second image should stay aligned to the bottom right corner of the first one.

The setup you can see in the code below works in browsers other than Firefox. In Firefox, the second image is positioned as far right as possible, up to the original width of the first image. I think I've narrowed it down to the 100% height I give .image div, if I use a fixed height (i.e. 400px), the second image is aligned correctly. I need the percentage height though, to let the first image scale to the text height.

.wrapper {
  overflow: hidden;
  position: relative;
}

.text {
  width: 50%;
  position: relative;
}

.image {
  width: 50%;
  position: absolute;
  left: 50%;
  top: 0;
  bottom: 0;
}

.image div {
  position: relative;
  display: inline-block;
  vertical-align: top;
  height: 100%;
  max-width: 100%;
  overflow: hidden;
}

.image div:after {
  content: url("https://vignette1.wikia.nocookie.net/uncyclopedia/images/6/67/Marvin_the_martian.jpg");
  display: block;
  position: absolute;
  bottom: 0;
  right: 0;
  width: 100px;
  height: 120px;
}

.image>div>img {
  display: block;
  height: 100%;
  width: auto;
}

<div class="wrapper">
  <div class="text">

You can see how it works in Codepen.

Any help would be appreciated.

Answer 1

It has to be a bug on firefox. Your code seems to be working under 1170px. So I have come up with a quick fix, I don't know whether it's applicable in your case or not.

CSS:

* {
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    box-sizing: border-box;
  }


.wrapper {
  overflow: hidden;
  position: relative;
  max-width: 1170px;

  margin-left: auto;
  margin-right: auto;
}

.text {
  width: 50%;
  position: relative;
}

.image {
  width: 50%;
  position: absolute;
  left: 50%;
  top: 0;
  bottom: 0;
}

.image div {
  position: relative;
  display: inline-block;
  vertical-align: top;
  height: 100%;
  max-width: 100%;
  overflow: hidden;
}

.image div:after {
  content: url("https://vignette1.wikia.nocookie.net/uncyclopedia/images/6/67/Marvin_the_martian.jpg");
  display: block;
  position: absolute;
  bottom: 0;
  right: 0;
  width: 100px;
  height: 120px;
}

.image>div>img {
  display: block;
  height: 100%;
  width: auto;
}
.big-wrapper {
  margin-left: auto;
  margin-right: auto;

}

Answer 2

Update

This second version, Demo 2, has been stripped of all flex, fixed position, and even intrinsic measurements (vw). Firefox works and even IE surprisingly. Changed the background-color to make it look spacier.

Major Changes

• Added html,body {height:100%;width:100%}
• .wrapper needed 100x100% as well.
• Now .image and .text has a parent that their percentages can relate to.
• Gave .image min-height:100%
• Removed both <img> and used background-image

Optional Changes

• Made .wrapper position:fixed

• Made .text and .image position:absolute

• .wrapper is a flex container

• .wrapper has overflow-y:scroll so at smaller widths, text can still be read and it's scroll instead of auto so there be no jumpy behavior when the scrollbar pops in and out.

• I also edited Marv as a PNG with a transparent background. P38 modulator not included.
