Answer 1

@keyframes words{
0%{transform:rotateX(-10deg) rotateY(-65deg) rotateZ(-60deg)};
25%{transform:rotateX(-35deg) rotateY(50deg) rotateZ(-15deg)};
50%{transform:rotateX(25deg) rotateY(-20deg) rotateZ(5deg)};
75%{transform:rotateX(20deg) rotateY(20deg) rotateZ(-10deg)};
100%{transform:rotateX(25deg) rotateY(-30deg) rotateZ(-50deg)};
}
Works. Put rotate... against the parentheses this way:
rotateX(...) rotateY(...) not
rotateX (...)rotateY (...)
You also had a typo? on the last line: rotateY twice instead of rotateZ.
