background-image css image-resizing responsive-design

Responsive css background images


I have a website ( and I want to make the background (in css I have defined a bg-image for the content) also responsive. Unfortunately I really don’t have any idea on how to do this except for one thing that I can think of but it’s quite a workaround. Creating multiple images and then using css screen size to change the images but I wanna know if there is a more practical way in order to achieve this.

Basically what I wanna achieve is that the image (with the watermark ‘G’) automatically resizes without displaying less of the image. If it’s possible of course


Code I have so far (content part)

#content {
  background-image: url('../images/bg.png');
  background-repeat: no-repeat;
  position: relative;
  width: 85%;
  height: 610px;
  margin-left: auto;
  margin-right: auto;

    Take a look at this link, might it be what you are looking for?

  • I feel like this solution that Christofer Vilander posted is a better solution than the chosen answer.

  • Just wondering why the site doesn’t actually implement this resizing feature you were asking about, as of Feb 2015? Was there some issue with it?

If you want the same image to scale based on the size of the browser window:


Do not set width, height, or margins.

The previous line about not setting width, height or margin refers to OP’s original question about scaling with the window size. In other use cases, you may want to set width/height/margins if necessary.

    Is it also possible to auto resize the width and let the height be fixed?

    Yes, you can set the height of the image in pixels and the width in percents, but the image will be destorted. It won’t look nice.

    You can use a much smaller image if you use a vector format:

    What? Not setting width, height to the container won’t show the image at all.

    (1) The original question was about scaling based on a browser window size. (2) Elements like div get their own height from their own content, or take available space in a flexbox model. Saying that without explicit width/height the container won’t show at all is incorrect. Obviously, if you want to display an empty div with a background image, you will need to set the height and, possibly, width, but then you will see only a part of an image, unless the aspect ratio is exactly the same as of the image itself.

by this code your background image go center and fix it size whatever your div size change , good for small , big , normal sizes , best for all , i use it for my projects where my background size or div size can change



  • At screen size 800x1280px, the image gets cut off on the right side by the box. All the other sizes seem fine.

Try this :

background-image: url(_images/bg.png);
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
background-size: cover;
