Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
And God said, “Let there be light,” and there was light.
God saw that the light was good, and he separated the light from the darkness.
God called the light “day,” and the darkness he called “night.” And there was evening, and there was morning—the first day.
And God said, “Let there be a vault between the waters to separate water from water.”
So God made the vault and separated the water under the vault from the water above it. And it was so.
God called the vault “sky.” And there was evening, and there was morning—the second day.Show all codeEdit CSS onlineThe plugin that remembers hundreds of CSS items for youEvery CSS property — in a live demonstrationThe bilingual CSS referencedefinitionexamplessyntaxmodulespecificationsourcesvisual demonstrationpreviousnext
