Scale is not the best option It will need some other adjustments  like margins paddings etc    but the right option is zoom  75

CSS will not be able to zoom on demand  but if you couple CSS with JS  you could change some values to make a page look bigger  However  as it has been said  this feature is standard nowadays in modern browsers  no need to replicate it  As a matter of fact  replicating it will slow down your website  more things to load  more JS or CSS to parse or execute and apply  etc

You might be able to use the CSS zoom property - supported in IE 5 5   Opera  and Safari 4  and Chrome   Can I use  css Zoom  Firefox is the only major browser that does not support Zoom  bugzilla item here  but you could use the  proprietary  -moz-transform property in Firefox 3 5   So you could use   div zoomed        zoom  3       -moz-transform  scale 3        -moz-transform-origin  0 0

If your CSS is constructed completely around ex or em units  then this might be possible and feasible  You d just need to declare font-size  150  in your style for body or html  This should cause every other lengths to scale proportionally  You can t scale images this way  though  unless they get a style too   But that s a very big if on most sites  anyway

Jon Tan has done this with his site - http   jontangerine com  Everything including images has been declared in ems  Everything  This is how the desired effect is achieved  Text zoom and screen zoom yield almost the exact same result

I have the following code that scales the entire page through CSS properties  The important thing is to set body style width to the inverse of the zoom to avoid horizontal scrolling  You must also set transform-origin to top left to keep the top left of the document at the top left of the window           var zoom   1          var width   100           function bigger                 zoom   zoom   0 1              width   100   zoom              document body style transformOrigin    left top               document body style transform    scale     zoom                    document body style width   width                          function smaller                 zoom   zoom - 0 1              width   100   zoom              document body style transformOrigin    left top               document body style transform    scale     zoom                    document body style width   width

This is a rather late answer  but you can use   body      transform  scale 1 1      transform-origin  0 0        add prefixed versions too      to zoom the page by 110   Although the zoom style is there  Firefox still does not support it sadly   Also  this is slightly different than your zoom  The css transform works like an image zoom  so it will enlarge your page but not cause reflow  etc     Edit updated the transform origin

As Johannes says -- not enough rep to comment directly on his answer -- you can indeed do this as long as all elements   dimensions are specified as a multiple of the font s size  Meaning  everything where you used    em or ex units   Although I think   are based on containing element  not font-size   And you wouldn t normally use these relative units for images  given they are composed of pixels  but there s a trick which makes this a lot more practical    If you define body font-size  62 5    then 1em will be equivalent to 10px  As far as I know this works across all main browsers   Then you can specify your  e g   100px square images with width  10em  height  10em  and assuming Firefox s scaling is set to default  the images will be their natural size   Make body font-size  125    and everything - including images - wil be double original size
