Is it possible to demolish already these hacks for ie?

Question

css

Hello! There is a bunch of css-nicknames, which over the years has acquired a bunch of unused styles for a long time, replacing a bunch of layout designers. I decided to clean it from the excess, at the same time run it through csslinter, an autoprefixer. In styles, a bunch of constructions like

vertical-align: middle;
    *vertical-align: auto;
    *zoom: 1;
    *display: inline;

or

position: relative;;
margin: 0 10px 0 0;;

As I understand it, these are some kind of hacks for gray-haired ie. Are they current or can they be demolished? And the eye is strained and the linter crashes with them.

Answer 1

Everything with an asterisk is IE6 hacks, they can already be demolished. And this just looks like a bug:

position: relative;;
margin: 0 10px 0 0;;
