javascript - Div height to image height and image width to div width -

-

i have div use container , image use "background" (not literally, told couldn't background attribute) , content div:

css

#container {   display:table;   width: 100%;   min-width:100%; }  .img1 {   //don't know put here; }  #content {   //not important; }

html

<div id="container">     <img class="img1" src="img.png"/>     <div id="content"> content </div> </div>

i need container div 100% screen width, , contained image, while both of them must have image's resulting height (after resizing taking 100% screen width) (no stretching). way that? tried lot of min-height , width combination nothing worked far. prefer css , html solutions, if possible.

not sure mean, how look: https://jsfiddle.net/b76fjtcv/

basically it's 

.img1 {width: 100%;}

this updated version of fiddle adds max width img doesn't fuzzy. set max-width of .img1 image's full width.
