Changing the html view of sites with javascript codes

Copy any code and paste it into the console from the inspect element on the site you want to try

Array.prototype.slice.call(  
 document.querySelectorAll(
    'div,p,span,img,a,body')).map(function(tag){
    tag.style['transform'] = 'rotate(' + (
    Math.floor(Math.random() * 3) - 1) + 'deg)';
});

setTimeout(function(){
 document.onmousemove = document.onkeypress = 
 function(){
     document.body.style['transition'] = 'transform 3s';
     document.body.style['transform'] = 'rotate(180deg)';

  allDivs[i].style['color'] = 'green';
