数据为image / jpeg时背景图像的宽高比； base64

Question

I have a div with background-image set to data:image/jpeg;base64 format:

<div style="background-image: url(data:image/jpeg;base64,/9j/4AAQ...

I would like to show full image respecting aspect ratio, using available space. I would normally use:

width: 90vw;
height: 100vh;
background-size: contain;
background-repeat: no-repeat;
background-position: center;

In this case image is stretched using full div size. Any suggestions?
