JS to implement rem

(function(win,factory){
 factory(win);
 window.addEventListener('resize',function(){factory(win)},false);
}(window,function(win){
 var width = document.documentElement.clientWidth;
 width = width > 750 ? 750 : width;
 document.documentElement.style.fontSize = width / 7.5 + 'px';
}));

Note

Here 1rem in the 750 psd design represents 100px;

switch The switching animation is implemented through the transition attribute of CSS3;
Mainly controls the movement of the after of the switch and the zoom-in and zoom-out animation of the before.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
