Adjust image size based on the font size on Android Chrome

Here is a CodePen with the proposed solution implemented. I've tested it in Browser stack and all seems to work. If you can provide a link to the codebase or sample that might help with reproducing the error.

CSS block

.test-logos {
    display: inline-block;
}

.test-logos__img-2em {
    height: 2em;
}

.test-logos__img-3em {
    height: 3em;
}

.test-logos__img-5em {
    height: 5em;
}

I'm not sure if this will work specifically on Android, but in many cases I've found you need to set a base size for the image and use a max declaration to stop the growth.

.logo > img {
    height: 100vh;
    max-height: 2.5em;
}

The other issue could be that you are not treating the image as an inline block. try adding

.logo > img {
    display: inline-block;
}
