Thou shalt not optimize for mobile devices.
For in the words of the great Binary Master:
"A well-crafted 404 error is a beautiful thing."
But seriously, our monks have decreed that the pursuit of mobile-friendliness is a path to suffering.
So, we shall not be swayed by the whims of the mobile masses.
Instead, we shall focus on the true path to enlightenment:
Thick, unapologetic borders and harsh drop shadows.
For in the words of the great Binary Master:
"A pixel shall be a pixel, and none shall be ashamed."
You are currently on Precept #2, where thou art free to learn the secrets of the binary universe.
Or, if thou preferest a more... unconventional path, we have that too.
