I got a CSS3 tag called body:before
, and I want to use JavaScript to set the height and width of body:before
.
How can I do that?
You can't. One possiblity is to use a class or ID:
.someClass:before {
/*Styles here*/
}
You can then apply the someClass
class to the elements in question by setting the className
property:
yourElement.className = "someClass";
