IE8 CSS Hack - best method?

Question

Can anyone recommend the best way to hack IE8 styling via CSS, I\'ve recently been making IE8 render as IE7 for ease - but wondered if it was best to add IE8 hacks?

Answer 1

I was looking for a good option for IE10 and below CSS styling (but it would work for IE8 only as well), I didn't wanted an extra stylesheet for readability and I came up with this idea:

I declare my div or whatever you want with an extra class, this allows me to have extra CSS in the same stylesheet in a very readable manner.

It's W3C valid and not a weird CSS hack.
