\nSimulating CSS3 box-shadow<\/code> in IE6-8 is<\/em> possible!<\/span>\n<\/div>\n
The above is not an image. It uses Allen R. Walden’s Neon Lights<\/a> font and cssSandpaper<\/a> to simulate CSS3 text-shadowing in IE. The box shadows are made with pure CSS in all browsers.<\/div>\n<\/div>\n

CSS3 Box-Shadows are a great to quickly decorate the outside of block-level elements.<\/strong> There are many CSS box-shadow recipes you can use to produce a variety of effects, including simple<\/strong>, glowing<\/strong> and blurred<\/strong> shadows. And, unlike CSS3 text-shadows<\/a>, box-shadows are natively supported by the latest version of IE.<\/strong> However, if you want them to appear in older versions of IE<\/strong> (i.e. 6 through 8), you will want to learn how to use a variety of Visual Filters to simulate them.<\/strong> This article will cover a few CSS3 box-shadow effects, the equivalent Visual Filter recipes for IE 6-8, and the differences between them. It will also cover the differences in the CSS3 implementations in all the modern browsers.<\/strong> Box-shadows like the example on the left is possible in all commonly used browsers.<\/p>\n

First off, what is a box-shadow<\/code>?<\/h2>\n

A box-shadow is equivalent to a CSS3 text-shadow<\/code><\/a> except it is applied to the box of the block-level element instead of the actual text. Just like text-shadows, you can have one shadow:<\/p>\n

\n
\r\n#box {\r\n  box-shadow: <x-offset><\/em> <y-offset><\/em> <blur-radius><\/em> <color><\/em>;\r\n}\r\n<\/pre>\n<\/blockquote>\n
… three shadows:<\/p>\n
\n
\r\n#box {\r\n  box-shadow: <x-offset1<\/sub>><\/em> <y-offset1<\/sub>><\/em> <blur-radius1<\/sub>><\/em>, <color1<\/sub>><\/em>,\r\n              <x-offset2<\/sub>><\/em> <y-offset2<\/sub>><\/em> <blur-radius2<\/sub>><\/em>, <color2<\/sub>><\/em>,\r\n              <x-offset3<\/sub>><\/em> <y-offset3<\/sub>><\/em> <blur-radius3<\/sub>><\/em>, <color3<\/sub>><\/em>;\r\n}\r\n<\/pre>\n<\/blockquote>\n
… or as many as you want.  The x-<\/code> and y-offset<\/code>s measure the position of the horizontal and vertical shadow respectively, and the blur-radius<\/code> measures the amount of blur in the shadow.  Let’s take a look at a simple example:<\/p>\n
\n
\r\n#box {\r\n  box-shadow: 5px 5px 0px #ff0000;<\/span>\r\n}\r\n<\/pre>\n<\/blockquote>\n\n\n\n\n\n

\n
\nThis is an example of a simple box-shadow without blurring\n<\/div>\n<\/td>\n
\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Note that although box-shadow<\/code> is the official property name, one must use the vendor-specific prefixes in order to use it in Webkit browsers (i.e. Chrome and Safari) as well as older versions of Firefox:<\/p>\n
\n
\r\n#box {\r\n  box-shadow: 5px 5px 0px #ff0000,          \/* Firefox 4.0+, Opera, IE 9 *\/\r\n  -webkit-box-shadow: 5px 5px 0px #ff0000,  \/* Chrome and Safari         *\/\r\n  -moz-box-shadow: 5px 5px 0px #ff0000;     \/* Firefox 3.6               *\/\r\n}\r\n<\/pre>\n<\/blockquote>\n
Furthermore, there are two optional parameters, the spread<\/em> (which allows you to determine the size of the shadow) as well as the inset<\/code> parameter that can allow you to put the shadow inside the box instead of outside of the box.  I direct readers to Mozilla.org’s great reference for box-shadow<\/code><\/a> to read more on these properties, since they are not, as far as I can tell, reproducible in IE 8 or lower. <\/p>\n
What about IE?<\/h2>\n
IE9 has no problem showing box-shadow<\/code><\/strong> except when shadowing a box within a table-cell<\/a> (If the CSS of the table has its border-collapse<\/code> property set to collapse<\/code> then the box-shadow<\/code> is not applied.  Hopefully this is fixed in a future release). <\/p>\n
As mentioned earlier, IE6-8 requires Visual Filters to simulate CSS3 box-shadows without JavaScript.<\/strong>  In order to illustrate this, I will show several different types of box-shadows below and show both the CSS3 syntax and the equivalent Visual Filter CSS recipe.  Some of these recipes produce almost identical results, while others are rough equivalents.  Note that all these examples use a variation of Paul Irish\u2019s Conditional CSS Pattern<\/a> in order to create the IE-only rules.  This involves replacing the <body><\/code> tag of the document with this HTML:<\/p>\n
\n
\r\n   <!-- Extra white-space below is just to make it easier to read. :-) -->\r\n\r\n   <!--[if lt IE 7 ]>   <body class=\"ie6\">          <![endif]-->\r\n   <!--[if IE 7 ]>      <body class=\"ie7\">          <![endif]-->\r\n   <!--[if IE 8 ]>      <body class=\"ie8\">          <![endif]-->\r\n   <!--[if IE 9 ]>      <body class=\"ie9\">          <![endif]-->\r\n   <!--[if (gt IE 9) ]> <body class=\"modern\">       <![endif]-->\r\n   <!--[!(IE)]><!-->    <body class=\"notIE modern\"> <!--<![endif]-->\r\n\r\n<\/pre>\n<\/blockquote>\n
We can then apply CSS specific to a version of IE.  For example:<\/p>\n
\n
\r\nbody.ie7 #box {\r\n   \/* insert IE7 specific CSS here *\/\r\n}\r\n<\/pre>\n<\/blockquote>\n
(Note:<\/strong> Paul Irish’s technique officially has the conditional comments around the html<\/code> tag, not the body<\/code> tag.  You can use either for these techniques to work.  I just prefer using the latter.)<\/p>\n
All these Visual Filter recipes depend on the box “having layout”<\/a>.<\/strong>  If you have any difficulty with the Visual Filters activating, set zoom: 1<\/code> or a static width inside the IE6-8 specific CSS to force the block to have layout.<\/p>\n
Type #1: Simple, Unblurred Shadows<\/h3>\n
In order to simulate simple, unblurred box-shadow<\/code>s in IE<\/strong>, we use IE’s DropShadow<\/code> Visual filter<\/a>: <\/p>\n
\n
\r\n#box {\r\n  \/* CSS for all browsers. *\/\r\n  border: solid 1px #808080;\r\n  background: #ffffcc;\r\n  margin: 10px;\r\n  padding: 10px;\r\n\r\n  \/* CSS3 Box-shadow code: *\/\r\n  box-shadow: 5px<\/span> 5px<\/span> 0px #ff0000<\/span>;\r\n  -webkit-box-shadow: 5px 5px 0px #ff0000;\r\n  -moz-box-shadow: 5px 5px 0px #ff0000;\r\n}\r\n\r\n\/* IE6-8 Specific Code *\/\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.DropShadow(OffX=5<\/span>, OffY=5<\/span>, Color=#ff0000<\/span>);\r\n}\r\n<\/pre>\n<\/blockquote>\n\n\n\n\n\n

\n
\nThis is an example of a simple box-shadow without blurring that also works in IE6-8.<\/strong>\n<\/div>\n<\/td>\n
\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
There are two exceptions to this solution.<\/strong> The first deals with when the block has a transparent background<\/strong>, and the other has to do with negative box-shadow offsets<\/strong>.<\/p>\n
Type #1a: Blocks With Transparent Backgrounds<\/h3>\n
Let’s say you use the above CSS, but omit the background<\/code> property:<\/p>\n
\n
\r\n#box {\r\n  \/* CSS for all browsers.  Note there is no background-color, so box will be transparent *\/\r\n  border: solid 1px #808080;\r\n  margin: 10px;\r\n  padding: 10px;\r\n\r\n  \/* CSS3 Box-shadow code: *\/\r\n  box-shadow: 5px 5px 0px #ff0000;\r\n  -webkit-box-shadow: 5px 5px 0px #ff0000;\r\n  -moz-box-shadow: 5px 5px 0px #ff0000;\r\n}\r\n\r\n\/* IE6-8 Specific Code *\/\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.DropShadow(OffX=5, OffY=5, Color=#ff0000);\r\n}\r\n<\/pre>\n<\/blockquote>\n
Doing this will results in some unexpected results in IE6-8:<\/p>\n\n\n\n\n\n

\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
The results in IE7 are as hideous and unreadable as the average YTMND<\/a> page! In order to fix this issue in elderly IE, one must add a background color in IE6-8 only and remove it with the Chroma<\/code> filter<\/strong> (more information on this technique can be found on my previous blog post, How to Make ClearType, @font-face Fonts and CSS Visual Filters Play Nicely Together<\/a>).<\/p>\n
\n
\r\n#box {\r\n  border: solid 1px #808080;\r\n  margin: 10px;\r\n  padding: 10px;\r\n\r\n  \/* Box-shadow code: *\/\r\n  box-shadow: 5px 5px 0px #ff0000;\r\n  -webkit-box-shadow: 5px 5px 0px #ff0000;\r\n  -moz-box-shadow: 5px 5px 0px #ff0000;\r\n}\r\n\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   background-color: #ffffff;\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.DropShadow(OffX=5, OffY=5, Color=#ff0000),\r\n           progid:DXImageTransform.Microsoft.Chroma(Color='#ffffff');<\/span>\r\n}\r\n<\/pre>\n<\/blockquote>\n
As you can see below, adding this CSS logic produces much better results:<\/p>\n\n\n\n\n\n

\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Note:<\/strong> All the other types of box-shadow recipes that follow should also use this Chroma filter method when it is desirable to have a transparent background in the box itself.<\/p>\n
Type 1b: Negative Shadow Offsets<\/h3>\n
If there are negative shadow offsets, you will see a small difference with the position of the box being shadowed:<\/p>\n
\n

\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
You will note that the offsets in IE push the box down and to the right.  This is because IE’s Visual Filters believes that the box-shadow as part of the box itself,<\/strong> while CSS3 believes that it should be outside of the box.<\/strong>  As a result, negative box-shadows shift the box in IE6-8.  In order to compensate for this, one can use margin-top<\/code> and margin-bottom<\/code> to move the shadow to where CSS3 thinks it should be:<\/p>\n
\n
\r\n#box {\r\n  \/* CSS3 Box-shadow code: *\/\r\n  box-shadow: -10px<\/span> -5px<\/span> 0px #ff0000<\/span>;\r\n  -webkit-box-shadow: -10px -5px 0px #ff0000;\r\n  -moz-box-shadow: -10px -5px 0px #ff0000;\r\n}\r\n\r\n\/* IE6-8 Specific Code *\/\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.DropShadow(OffX=-10<\/span>, OffY=-5<\/span>, Color=#ff0000<\/span>);\r\n   margin-top: 10px<\/span>;\r\n   margin-left: 5px<\/span>;\r\n}\r\n<\/pre>\n<\/blockquote>\n\n\n\n\n\n

Note that one could also make use relative positioning and use the CSS top<\/code> and left<\/code> properties to do the same thing in IE.  I leave it up to readers to decide which method would be more appropriate for the situation they find themselves in.<\/p>\n
Type #2: Glowing box-shadow<\/code><\/h3>\n
The second box-shadow<\/code> I use a lot is what I call the “glowing box” effect.  This happens when a shadow with a large blur radius is put directly behind a box (i.e. the x- and y-offsets are set to 0, and the blur-radius is a non-zero number). It is possible to simulate this effect in IE using the Shadow<\/code> filter. This filter must be applied four times (north, south, east and west of the box) in order to simulate the CSS3 effect.  Here is the CSS recipe:<\/p>\n
\n
\r\n#box {\r\n   box-shadow: 0 0 5px #666666;\r\n   -webkit-box-shadow: 0 0 5px #666666;\r\n   -moz-box-shadow: 0 0 5px #666666;\r\n}   \r\n\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=0),\r\n         progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=90),\r\n         progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=180),\r\n         progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=270);\r\n}\r\n<\/pre>\n<\/blockquote>\n
… and here are the results as rendered in Firefox 4 and IE7:<\/p>\n\n\n\n\n\n

\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Note that the color in the Visual Filter syntax is lighter than the CSS3 one.  In order to get the equivalent IE color, I take a screenshot of the CSS3 box-shadow, open the image in The GIMP or Photoshop, and find the color that is just outside of the box.  This is the color I use in the IE syntax.  If you don’t want to go through all this trouble, you can also guess, which is what I do if I’m lazy.  Which is a lot of the time.<\/p>\n
You can increase the blur radius\/strength to produce larger glows as well:<\/p>\n
\n
\r\n#box {\r\n    box-shadow: 0 0 15px #cccccc;\r\n   -webkit-box-shadow: 0 0 15px #cccccc;\r\n   -moz-box-shadow: 0 0 15px #cccccc;\r\n}\t\r\n\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.Shadow(Color=#eeeeee, Strength=15, Direction=0),\r\n           progid:DXImageTransform.Microsoft.Shadow(Color=#eeeeee, Strength=15, Direction=90),\r\n           progid:DXImageTransform.Microsoft.Shadow(Color=#eeeeee, Strength=15, Direction=180),\r\n           progid:DXImageTransform.Microsoft.Shadow(Color=#eeeeee, Strength=15, Direction=270);\r\n}\r\n<\/pre>\n<\/blockquote>\n\n\n\n\n\n

Sure, the IE7 screenshot looks slightly different from the Firefox one, but let’s take a look at what all the modern browsers look with exactly the same CSS code:<\/strong><\/p>\n\n\n\n\n\n\n\n\n\n
Opera<\/th>\nIE 9<\/th>\n<\/tr>\n<\/thead>\n
\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n
Safari 5<\/th>\nChrome 13<\/th>\n<\/tr>\n<\/thead>\n
\n\n<\/td>\n\n\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
They are all slightly different.  It is almost impossible to be pixel perfect with blurred box-shadows unless you give different rules to the different browsers using vendor-specific prefixes.<\/p>\n
Two important caveats about the Visual Filter rules:<\/p>\n
    \n
  1. As mentioned before, the CSS for IE6-8 uses a lighter color for the shadow.  This is due to the way the Shadow<\/code> filter behaves: it requires a lighter shade to simulate the same effect.<\/li>\n
  2. Note that the Visual Filters examples are pushed down and to the right compared to the CSS3 example.<\/strong>  This is for the same reasons as stated in Type 1b<\/a>, and a developer would again have to use margins or positioning to get the box in exactly the same place as it is in IE6-8:
    \n
    \n
    \r\n#box {\r\n   box-shadow: 0 0 5px #666666;\r\n   -webkit-box-shadow: 0 0 5px #666666;\r\n   -moz-box-shadow: 0 0 5px #666666;\r\n}   \r\n\r\nbody.ie6 #box,\r\nbody.ie7 #box,\r\nbody.ie8 #box {\r\n   margin-left: -5px;\r\n   margin-top: -5px;<\/span>\r\n   zoom: 1;\r\n   filter: progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=0),\r\n         progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=90),\r\n         progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=180),\r\n         progid:DXImageTransform.Microsoft.Shadow(Color=#cccccc, Strength=5, Direction=270);\r\n}\r\n<\/pre>\n<\/blockquote>\n<\/li>\n<\/ol>\n
    Type #3: Blurred box-shadow<\/code><\/h3>\n
    Up until a few days ago, I thought this last type of text-shadow could not be simulated in IE using just CSS.  I then came across an interesting recipe from CSS-Tricks<\/a> and this demo by Christian \u201dSchepp\u201d Schaefer<\/a>. These CSS recipes came close, but was not able to control the color of the shadow itself (it assumed grey shadows only) or the exact location of the shadow.  I decided to take this work to the next level and add full control of the text-shadow, with some nice results:<\/p>\n\n\n\n\n\n

    Yes, the Legacy-IE Specific CSS as long and as painful like a meeting with your accountant,<\/strong> but it gets the job done.  <\/p>\n
    Conclusion<\/h2>\n
    These Visual Filters CSS recipes can come handy when you want IE6-8 to have similar box-shadow effects that modern web browsers have.  There are probably other types of box-shadows that can be handled using them, and if you are interested I encourage those with time and patience to check out Microsoft’s reference to Visual Filters and start playing with them.  Although Visual Filter support will probably be taken out of IE10, developers won’t need worry since IE9 already has box-shadow support — these experiments should only be used to add box-shadow support in older versions of IE.<\/p>\n
