Div fit according image width

[kopaula95]

I have a portfolio page with a image display with zoom.I have this code: http://codepen.io/Mpleandro/pen/LvrqJThe div that shows the image has a class of \[code\].display\[/code\], on line 13 of the HTML and the css formating for this div isline 90.The image width will be flexible, so I what I want is to make the containing div inherit the width of image.I tried the css property \[code\]auto\[/code\], \[code\]inherit\[/code\] and \[code\]min-with\[/code\], but nothing works!Could someone help me?P.S.: I need a responsive solution.Thanks
