The zoom property in CSS allows you to scale your content. It is non-standard, and was originally implemented only in Internet Explorer. Although several other browsers now support zoom, it isn't recommended for production sites.

.zoom {
  zoom: 150%;

The "supported: values are:

  • percentage - Scale by this percentage
  • number - Convert to percentage and scale - 1 == 100%; 1.5 == 150%;
  • normal - zoom: 1;

If your browser supports it, you'll see these images as different sizes:

Check out this Pen!

Zoom is an old IE thing. It isn't something you should use on live sites. If you want to scale content, use CSS Transforms. You can also use filters if you need oldIE support.

Back in the days of IE6, zoom was used primarily as a hack. Many of the rendering bugs in both IE6 and IE7 could be fixed using zoom. As an example, display: inline-block didn't work very well in IE6/7. Setting zoom: 1 fixed the problem. The bug had to do with how IE rendered its layout. Setting zoom: 1 turned on an internal property called hasLayout, which fixed the problem.

Any 4.0+ None None 5.5+ TBD TBD

Safari also supports zoom since version 4. However, it added a new value: reset. That tells the browser not to zoom your element on zoom. So your cmd/ctrl+? It doesn't work on elements with zoom: reset applied.

      Well actually Vikram its a wrong place to ask this question you can ask it on forum :) but well regarding your solution, its good to use positioning to the div and drop it over the image, give image a z-index value less then the z-index value of div and the div will be shown on the top of the moving banner :)

      I hope this will help you.

      if not email me the files i will code it for you :)

    Give z-index value higher in image then the div

    .img {z-index:1000}
    #div {z-index:10}

      True. If I quote the article:

      It isn’t something you should use on live sites.

      Plus, seeing as Firefox & Opera have no support for it at all, and any use of zoom would be quite layout-critical or display-critical, it’s certainly not a good idea to use it at all.

      I’ve found zoom comes in handy when you want to have a feature of imitating the page zoom in and out like when you hit command/control-minus and command/control-equal. You can put it on the html element and control it through JavaScript. As far as I can tell, there’s no way to do that through transforms. It has to be a progressive enhancement sort of thing though, as it only works on webkit/blink browsers ( Safari, Chrome, Opera, Maxthon). It does not work on IE or Firefox.

      Best not to use it because Browsers like Firefox and Opera are pretty popular and you don’t want your page breaking. That being said, however, I use it (sparingly) when converting websites to mobile. Specifically when dealing with elements who’s background-images are sprites. It’s honestly being lazy, but it’s a quick solution. Why would it be okay in mobile? Because the two most popular browsers on mobile support it (Chrome and Safari). But again, if you can do just avoid using it. Use it in the lower scale section where you know that the screen is mobile size only something like @media

      (max-size: 380px){
              zoom: 0.8;

      But anyway, that’s what I would do.

    I am facing a different issue with zoom in ie
    I am using jquery animations on page and i need to have a min height and width of page so content doesn’t overlap with the header above, so for screen with smaller resolution (less than 1150 wide) i have set zoom to .075 on the div containing animation.

    This works perfectly in other browsers, but in IE content is squeezed to take 75% of screen space, but in other browser content takes the full screen width but area is increased to 125%.

    do you have any suggestion on how to fix it?

    I don’t agree that zoom shoudn’t be used on a live webpages. It should be used but with transform: scale fallback. Why? Beacuse in WebKit engine zoom property scale content like vector image and transform: scale works like on raster image which looks very ugly when we scale up content.

    So we should use zoom for WebKit and Trident and tranform: scale for rest.

    Can someone help me with centering a web page on different size monitors and different web browsers? If I zoom the browser to 110%, it looks perfect on a 24 inch monitor and if zoomed to 90%, it looks perfect on a 19 inch monitor. Can this be included in the css code? Thanks in advance

    Zoom is the best way sometimes to zoom the page. Unfortunately isn’t css standard, but I hope it will be.
    transform: scale() behaves tooooooo differently: for example if you want to zoom the whole page it creates more margins around. Zoom instead zooms each thing the right way like the browser ctrl + wheel behavior: I think that they are complementary and sometime is needed one other times is needed the other. Hope future css implementations will allow to use both, each one with its own behavior.

    ‘zoom’ is a factor that applies to font sizes, image sizes, and the content in general, whilst preserving the actual width of the content, and letting text wrap and drop down. For instance, it simulates zooming in on the page (ctrl +).

    ‘transform’ applies an arbitrary affine transform to the element exclusively for when rendering it; thus the parent element sees it as the same size. And, when upscaling it, it does NOT stay the same width or cause text to wrap, but passes its parent element’s bounds.
