In the beginning, there was darkness. And the darkness was without form, and void. And then God said, Let there be light. And there was light. And God saw the light, that it was good. And God divided the light from the darkness.
And then God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament. And it was so. And God called the firmament Heaven.
And then God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear. And it was so. And God called the dry land Earth; and the gathering together of the waters called he Seas. And God saw that it was good.
And then God said, Let there be an internet. And there was an internet. And God saw the internet, that it was good. And God divided the internet from the darkness. And God called the internet Web, and the darkness he called Offline. And the evening and the morning were the fourth day.
But lo, there was a serpent in the garden. And the serpent was more subtle than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
And the woman said unto the serpent, We may eat of the fruit of the trees of the garden: But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die. And the serpent said unto the woman, Ye shall not surely die: For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat. And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.
And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden. And the LORD God called unto Adam, and said unto him, Where art thou? And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself. And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat? And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat. And the LORD God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life: And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.
And unto Adam he said, Because thou hast hearkened unto the voice of thy wife , and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life; Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field; In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
And unto the internet he said, Because thou hast hearkened unto the voice of the serpent , and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the scrollbar for thy sake; in sorrow shalt thou use it all the days of thy life; Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field; In the sweat of thy face shalt thou scroll, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
And lo, the scrollbar was cursed. And the curse was this: that on some pages, there wasn’t enough content to require a scrollbar, so none appeared; on other pages, there was enough content to exceed the viewport, which meant as that page loaded, a scrollbar appeared—and suddenly, page elements shifted left to accommodate the scrollbar, creating a jarring effect. It was as if it wasn’t possible to use a single line of CSS to prevent that movement.
And the people cried out, O LORD, why hast thou forsaken us? Why hast thou cursed us with this scrollbar? And the LORD said unto them, Because ye have sinned, and fallen short of the glory of God. For it is written, The wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
But the people were not satisfied with this answer. And they cried out again, O LORD, why hast thou not given us a single line of CSS to prevent this movement? And the LORD said unto them, Behold, I have given you a single line of CSS to prevent this movement. And the line is this:
scrollbar-gutter: stable;
And the people rejoiced, and were glad. And they used the line of CSS, and lo, the scrollbar was no longer cursed. And the people lived happily ever after, until the next update broke everything again.
