I found the following code while reading a related question at this page: Rotate a webpage clockwise or anticlockwise
html {
-webkit-transform: rotate(180deg);
-moz-transform: rotate(180deg);
}

My question is how do I set this CSS via JavaScript?
When a visitor clicks on an image, I want to use JavaScript to modify the HTML tag's style using the settings above.
Thanks in advance.
The easiest way to do this is by putting this in a class, and assigning that class dynamically using JavaScript:
html.rotateme {
-webkit-transform: rotate(180deg);
-moz-transform: rotate(180deg);
}
document.documentElement.setAttribute('class', 'rotateme'); //Note that this will override the current class
Since you're using a very recent CSS feature, you probably don't need to support older browsers. Therefore, you can also use Element.classList to add a class.
To prevent this from throwing an exception in older browsers, you can check for the existance of it first:
document.documentElement.classList && document.documentElement.classList.add('rotateme'); //This won't override the current class
You use the style attribute on the HTML node.
Something like this will do it:
var htmlNode = document.documentElement;
htmlNode.style.webkitTransform = 'rotate(180deg)';
htmlNode.style.mozTransform = 'rotate(180deg)';
Then, to undo the rotate, set the values to an empty string:
var htmlNode = document.documentElement;
htmlNode.style.webkitTransform = '';
htmlNode.style.mozTransform = '';
Simple
$('#wrap').on('click',function(){
$('html').css('-webkit-transform','rotate(180deg)');
$('html').css('-moz-transform','rotate(180deg)');})
**JQUERY**
$("#imgID").on("click", function(){
$('html').css({"-webkit-transform": "rotate(180deg)", "moz-transform": "rotate(180deg)"});
});
only js
use user2428118's answer, it's a solid solution.
define a class for this:-
.htmlrotate {
-webkit-transform: rotate(180deg);
-moz-transform: rotate(180deg);
}
onclick of the button, run this:-
document.documentElement.classList.add('htmlrotate');
$('html').bind('click', function () {
$('html').css({
'-webkit-transform': 'rotate(90deg)',
' -moz-transform': 'rotate(90deg)'
})
});
