How does google do the barrel roll?

Question

If you Google, \'do a barrel roll\', the whole page does a 360 rotation. Does anyone have any guesses as to how Google is doing this? I disabled javascript, and it still occurre

Answer 1

If you look at the css code :

body {
    -moz-animation-duration: 4s;
    -moz-animation-iteration-count: 1;
    -moz-animation-name: roll;
}

Answer 2

Add a link with something like that:

javascript:(function(){var s=document.createElement('style');s.innerHTML='%40-moz-keyframes roll { 100%25 { -moz-transform: rotate(360deg); } } %40-o-keyframes roll { 100%25 { -o-transform: rotate(360deg); } } %40-webkit-keyframes roll { 100%25 { -webkit-transform: rotate(360deg); } } body{ -moz-animation-name: roll; -moz-animation-duration: 4s; -moz-animation-iteration-count: 1; -o-animation-name: roll; -o-animation-duration: 4s; -o-animation-iteration-count: 1; -webkit-animation-name: roll; -webkit-animation-duration: 4s; -webkit-animation-iteration-count: 1; }';document.getElementsByTagName('head')[0].appendChild(s);}());

Answer 3

As said above, with CSS3 animations and transform.

Wesbo showed a way to apply the effect on any site. You can view a demo and instruction here.

@-webkit-keyframes roll {
from { -webkit-transform: rotate(0deg) }
to   { -webkit-transform: rotate(360deg) }
}

@-moz-keyframes roll {
from { -moz-transform: rotate(0deg) }
to   { -moz-transform: rotate(360deg) }
}

@keyframes roll {
from { transform: rotate(0deg) }
to   { transform: rotate(360deg) }
}

body {
-moz-animation-name: roll;
-moz-animation-duration: 4s;
-moz-animation-iteration-count: 1;
-webkit-animation-name: roll;
-webkit-animation-duration: 4s;
-webkit-animation-iteration-count: 1;
}

Answer 4

It's a CSS Transition: https://developer.mozilla.org/en/CSS/CSS_transitions

-moz-transform: rotate(360deg);
-moz-transition-property: all;
-moz-transition-duration: 5s;

Example for Mozilla above, use -o and -webkit to target other browsers.

Answer 5

sounds like a css3 rotation transformation applied to either the body or html tags

Answer 6

if you want infinite

 @-moz-keyframes spin { 100% { -moz-transform: rotate(360deg); } }
 @-webkit-keyframes spin { 100% { -webkit-transform: rotate(360deg); } }
 @keyframes spin { 100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); } }
 body{-webkit-animation: spin 9.9s infinite linear;}
