Hi,

When I want to replace the old unit the size of a new, and when I prescaling the window size, rem is not precise. Examle below.

1px when converting to rem is invisible.

Firefox and IE10 scaling pretty good.


body {
font-size:62.5% /* ==> 10px */
}

div {
border: .1rem solid red /* ==> 1px */
}
