Is there a meta tag or something for desktops that works like viewport initial-scale?

I know you're thinking that this is a strange request, however I am currently dealing with a client that gave me a template and decided he wanted it 70% smaller after seeing it in a browser and all the HTML done (!!!!). Thus throwing all the work that was done for both of us out the window. If I could adjust the scale to 0.7 (70%) that would be perfect and the project can still roll out the 开发者_运维问答way it was going. Thank you!

body {
zoom: 0.7;
transform: scale(0.7);
transform-origin:0 0;
-ms-transform: scale(0.7);
-ms-transform-origin:0 0;
-moz-transform: scale(0.7);
-moz-transform-origin: 0 0;
-o-transform: scale(0.7);
-o-transform-origin: 0 0;
-webkit-transform: scale(0.7);
-webkit-transform-origin: 0 0;
}

You might be able to use the CSS Zoom property but negativly? - supported in IE 5.5+, Opera, and Safari 4, and Chrome (verifed, please check before downvoting).

Firefox is the only major browser that does not support Zoom (Check here) but you could use the "proprietary" -moz-transform property in Firefox 3.5.

So you could use:

div.zoomed { zoom: 70%; -moz-transform: scale(.7); }
