css - How to set a div size to its background image size -

- 

<div class="newsblocks"></div>

css:

.newsblocks{      background: url(../img/news/1.png); }

how set div size of 1.png?

it's not possible auto-size div based on size of it's background image, (hacky) way, including img tag url image, setting img visibility:hidden; [used inline css brevity - don't kill me!]:

<div style="background-image: url('img.jpg');">     <img src="img.jpg" style="visibility:hidden"/> </div
