html - CSS如何实现多重背景+渐变？

Question

这段代码是我从css graident generator得到的，渐变底部是透明的

background: -moz-linear-gradient(top,  rgba(248,246,247,1) 0%, rgba(248,246,247,0) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(248,246,247,1)), color-stop(100%,rgba(248,246,247,0))); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  rgba(248,246,247,1) 0%,rgba(248,246,247,0) 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  rgba(248,246,247,1) 0%,rgba(248,246,247,0) 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  rgba(248,246,247,1) 0%,rgba(248,246,247,0) 100%); /* IE10+ */
background: linear-gradient(to bottom,  rgba(248,246,247,1) 0%,rgba(248,246,247,0) 100%); /* W3C */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#f8f6f7', endColorstr='#00f8f6f7',GradientType=0 ); /* IE6-9 */

现在我想在渐变背景之上添加一个背景

background: url('../images/letter_head.png') left top repeat-x, #f8f6f6;

如何将它们结合起来？

Answer 1

只需将图片的网址添加到您的每个规则中即可。

background: url(someurl), -moz-linear-gradient(top,  rgba(248,246,247,1) 0%, rgba(248,246,247,0) 100%); /* FF3.6+ */

或者，如果您不想在每个规则中添加 url(etc)，您可以只指定一个 background-image 规则:

background: -moz-linear-gradient(top,  rgba(248,246,247,1) 0%, rgba(248,246,247,0) 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(248,246,247,1)), color-stop(100%,rgba(248,246,247,0))); /* Chrome,Safari4+ */
...
background-image:url("someurl");
