Here is the brief list of CSS Hacks. I will be writing more on CSS hacks soon. But this is one of the most regularly used features by me. So i would rather have it stored than search for it everytime

E 6 and below

* html {}

IE 7 and below

*:first-child+html {} * html {}

IE 7 only

*:first-child+html {}

IE 7 and modern browsers only

html>body {}

Modern browsers only (not IE 7)

Recent Opera versions 9 and below

For now, you can use these as a simple CSS hacks. I will be adding many more hacks later on. These are actually for my colleages to refer when I am not there, but I thought it might as well help you all also. Do remember to bookmark this topic and visit it regularly for updates on new CSS hack techniques. Also coming soon is a way to apply hack without w3c konwing it
