Basic CSS Features Not Working In IE8

I am completely at a loss here. I'm developing a website that needs to support a large group of users who are using IE8. Everything works in IE9 and above, as well as Chrome, Fire

Solution 1:

IE8 doesn't support rem as a unit. Use em or px instead.

Alternatively you could do something like:

#loginName{
    height:1.6em; // Or another value
    height:1.6rem;
}

to provide a IE8 fallback.
