   Logo sekolah naungan

   Kedua logo berbeda bentuk, jadi disamakan menurut LUAS OPTIS — bukan tinggi
   kotak. Menyamakan tinggi akan membuat logo lebar (SMK) mendominasi logo
   tegak (SMA Plus).

     SMA Plus  240x340  rasio 0.706 (perisai tegak)
     SMK       301x270  rasio 1.115 (lingkaran melebar)

   Luas sama  ->  h1/h2 = sqrt(1.115 / 0.706) = 1.257
     SMA Plus  170px tinggi -> 120px lebar -> luas 20.400
     SMK       135px tinggi -> 151px lebar -> luas 20.385

   Kedua berkas sudah dipangkas rapat ke isinya, jadi tinggi CSS = tinggi
   tampak. Kalau logo diganti, ulangi rumus di atas dengan rasio yang baru.
