IEBlog : Site Compatibility and IE8
Here’re a couple of methods for coding to IE8 (new hacks! d’oh!):
Initial CSS Property Values
| Unset properties on the currentStyle object now return their initial value. Relying on the old initial values for CSS properties such as z-index can cause problems. This is the root cause of issues with the ASP.NET menu control. | SOLUTION: Perform a check for both the backwards compatible value and the standardized initial value. |
| var zIndex = elm.currentStyle.zIndex; if(zIndex == 0) { // custom code } |
var zIndex = elm.currentStyle.zIndex; if(zIndex == 0 || zIndex == “auto”) { // custom code } |
