Remove IE6/7 prefix support

[cupcakearmy]

Hey there, first of all: love the project!

Building with parcel fails because of:

*/
/* Nicolas Gallaghers Clearfix solution
   Ref: http://nicolasgallagher.com/micro-clearfix-hack/ */
.cf:before, .cf:after { content: " "; display: table; }
.cf:after { clear: both; }
.cf { *zoom: 1; }     <------------------------------------------------------- This here
.cl { clear: left; }
.cr { clear: right; }
.cb { clear: both; }
.cn { clear: none; }
/*

The prefix breaks moders css parsers as it's not valid CSS. Is IE6/7 support still relevant? Would be great to drop that.

Been the thorn in my side for months... Can't find a better replacement for basscss than tachyons (hucssley doesn't have a stable release yet), don't wanna use clunkier build tools than parcel, don't wanna keep using outdated parcel versions.

Judging from the git dates, this project isn't active anymore?

#701 has done the work already

It's basically abbandoned at this point unfortunately :/

Agreed! Let's get rid of

.cf {
    *zoom: 1;
}

I guess this is abandoned... just had to copy the file into my repo and edit them, then uninstall tachyons

It isn't abandoned, it would be a breaking change to v4 to remove so this will not be removed in v4.
