HTML5有意思的实现

网页翻转180度

html{    filter:fliph}body{    -webkit-transform: rotateY(180deg);    -moz-transform: skew(0deg, 180deg) scale(-1, 1);    -o-transform: skew(0deg, 180deg) scale(-1, 1);    transform: rotateY(180deg);}

网页变灰

html{   filter: grayscale(100%);    -webkit-filter: grayscale(100%);    -moz-filter: grayscale(100%);   -ms-filter: grayscale(100%);    -o-filter: grayscale(100%); filter: url("data:image/svg+xml;utf8,<svg xmlns=\'http://www.w3.org/2000/svg\'><filter id=\'grayscale\'><feColorMatrix type=\'matrix\' values=\'0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0\'/></filter></svg>#grayscale");  filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);   -webkit-filter: grayscale(1);}
