hi.
i add image to the form.background.filename

i add login.css to stylesheet.filename (alsow put it in css property)

body  {
  background-repeat: no-repeat;
  background-position: center;
  background-size: cover;
  font-family: Arial, Helvetica, sans-serif;
}

.menuContainer{
font-size: 15px !important;
}


the image (in chrom) cut by half and view just the lowersection of the image.
in firefox - all fine.
