CSS rotate property in IE

I want to rotate the DIV to a certain degree. In FF it functions but in IE I am facing a problem.

For example in the following style I can set rotation=1 to 4

 filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=1);

This means that the DIV will be rotated to 90 or 180 or 270 or 360 degree. But if I need to rotate the DIV only 20 degrees, then it doesn't work anymore.

How may I solve this problem in IE?

To rotate by 45 degrees in IE, you need the following code in your stylesheet:

filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(SizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476)"; /* IE8 */

You’ll note from the above that IE8 has different syntax to IE6/7. You need to supply both lines of code if you want to support all versions of IE.

The horrible numbers there are in Radians; you’ll need to work out the figures for yourself if you want to use an angle other than 45 degrees (there are tutorials on the internet if you look for them).

Also note that the IE6/7 syntax causes problems for other browsers due to the unescaped colon symbol in the filter string, meaning that it is invalid CSS. In my tests, this causes Firefox to ignore all CSS code after the filter. This is something you need to be aware of as it can cause hours of confusion if you get caught out by it. I solved this by having the IE-specific stuff in a separate stylesheet which other browsers didn’t load.

All other current browsers (including IE9 and IE10 — yay!) support the CSS3 transform style (albeit often with vendor prefixes), so you can use the following code to achieve the same effect in all other browsers:

-moz-transform: rotate(45deg);  /* FF3.5/3.6 */
-o-transform: rotate(45deg);  /* Opera 10.5 */
-webkit-transform: rotate(45deg);  /* Saf3.1+ */
transform: rotate(45deg);  /* Newer browsers (incl IE9) */

Hope that helps.

Edit

Since this answer is still getting up-votes, I feel I should update it with information about a JavaScript library called CSS Sandpaper that allows you to use (near) standard CSS code for rotations even in older IE versions.

Once you’ve added CSS Sandpaper to your site, you should then be able to write the following CSS code for IE6–8:

-sand-transform: rotate(40deg);

Much easier than the traditional filter style you'd normally need to use in IE.

Edit

Also note an additional quirk specifically with IE9 (and only IE9), which supports both the standard transform and the old style IE -ms-filter. If you have both of them specified, this can result in IE9 getting completely confused and rendering just a solid black box where the element would have been. The best solution to this is to avoid the filter style by using the Sandpaper polyfill mentioned above.

You'll need to do a matrix transform as follows:

filter: progid:DXImageTransform.Microsoft.Matrix(
  M11 = COS_THETA,
  M12 = -SIN_THETA,
  M21 = SIN_THETA,
  M22 = COS_THETA,
  sizingMethod = 'auto expand'
);
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(
  M11 = COS_THETA,
  M12 = -SIN_THETA,
  M21 = SIN_THETA,
  M22 = COS_THETA,
  SizingMethod = 'auto expand'
)";

Where COS_THETA and SIN_THETA are the cosine and sine values of the angle (i.e. 0.70710678 for 45°).

There exists an on-line tool called IETransformsTranslator. With this tool you can make matrix filter transforms what works on IE6,IE7 & IE8. Just paste you CSS3 transform functions (e.g. rotate(15deg) ) and it will do the rest. http://www.useragentman.com/IETransformsTranslator/

Scroll down to '.box_rotate' for the Microsoft IE9+ prefix. Similar discussion here: https://stackoverflow.com/questions/382591/rotating-a-div-element-in-jquery

Just a hint... think twice before using "transform: rotate()", or even "-ms-transform :rotate()" (IE9) with mobiles!

I've been knocking hard to the wall for days. I have a 'kinetic' system going on, that slides images and, on top of it, a command area. I did "transform" on an arrow button so it simulates pointing up and down... I've reviewd the 1.000 plus code lines for ages!!! ;-)

All ok, once I removed transform:rotate from the CSS. It's a bit (not to use bad words) tricky the way IE handles it, comparing to other borwsers.

Great answer @Spudley! Thanks for writing it!

Usefull Link for IE transform

This tool converts CSS3 Transform properties (which almost all modern browsers use) to the equivalent CSS using Microsoft's proprietary Visual Filters technology.

For IE11 example (browser type=Trident version=7.0):

image.style.transform = "rotate(270deg)";
