Tumblr中有这种新型的标题，你有一个包含的盒子，里面有一个BG，当你滚动页面时，它会滚动。 但是我发现它在包含的区域不起作用。 我已经尝试了一切。 这是我下面的代码：
background-image: url(https://static.tumblr.com/cqouips/64cpa8678/cool-blue-fire-backgrounds-4013-hd-wallpapers.png);
background-attachment: fixed;
background-repeat: repeat;
font-size: 12px;
background-color: #000;
font-family: 'Quicksand', sans-serif;
color: #dbdbdb;
padding: 1px;
text-shadow: 1px 1px 0px #000, 1px -1px 0px #000, -1px -1px 0px #000, -1px 1px 0px #000, 0px 1px 0px #000, 0px -1px 0px #000, 1px 0px 0px #000, -1px 0px 0px #000;
padding: 6px 15px 6px 15px;
letter-spacing: 1px;
border: 2px double #f1f1f1;
text-transform: uppercase;
letter-spacing: 3px;
text-align: center;
