  1. Hi, I have a page on which I have a div inside a div. <div name="divWrapper" id = "divWrapper" style="overflow:auto;height:90vh;width:98vw" > <div style="-ms-transform-origin:0 0;-webkit-transform-origin:0 0;-moz-transform-origin: 0 0;overflow:visible;" name="divMap" id="divMap"> <img and ... imagemap tags> The result I'm looking for is an image is in the window, with scollbars around it. I have a script that's run when the user clicks a button and zooms the inner div to make the image bigger or smaller. I have an imagemap for the image, and I found that just resizing the image didn't resize the map, so the coordinates would be off. But if I put the whole thing in a div and resized THAT, it would work. Here's the script that "zooms" the inner div (curScale is set to 1 earlier in the *.js page): function zoomDiv(elementID,change) { var d = document.getElementById(elementID); var newScale; if (change == 0) { newScale = 1; } else { newScale = curScale * change; } var s = "scale(" + newScale + "," + newScale + ")"; d.style.transform = s; d.style.webkitTransform = s; d.style.MozTransform = s; d.style.msTransform = s; curScale = newScale; d.style.width = d.style.width * curScale; d.style.height = d.style.height * curScale;} I'm sure there are better ways to do what I'm trying to do with a lot of this, but it's kind of a slapped togethr page and I'm really interesting in fixing this... Without the transform-origin tags, if I resize the div by making it smaller (zooming "out"), the left side of the div moves to the right, almost as if it's trying to right-justify itself on the page (or in the outer div). If I increase the size back to the original, it doesn't move back to the left. WITH the transform-origin tags, it sticks to the top-left, but is ugly when I make it really small; I'd rather it be centered. So, how can I have a div that when I use transform to shrink or grow its contents, stays at a fixed % of the visible window, and is centered. I cannot use jquery because this is run locally on a workstation (a mac, with web sharing enabled) which may or may not have internet access and from what I have read, all that jquery code links to their site somehow. Thanks, Jeff
