Why won't the vertical margins between <p> and <hr> collapse in IE7
- by Nicolas
Hello all,
Perhaps I am missing something, but I can't explain this from any IE bug I know of. Why in this example do the margins of the <p> and <hr> elements collapse as expected in standards compliant browsers (i.e. FF3, IE8, etc) but not in IE7 (including IE8 compatibility mode)?
