Question

现在我发现这已经是SO了，每个人似乎认为它很有效How do I combine a background-image and CSS3 gradient on the same element?

由于某种原因，当我这样做时，它失败了。图像单独工作，渐变也是如此。我做错了什么？

.cSub {
  background: #00f;
  background-image: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -moz-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);
  background-image: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -webkit-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);
  background-image: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -o-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);
  background-image: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -ms-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);
  background-image: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, linear-gradient(135deg, #0088b7 0%, #006da4 100%);
  border-top: 2px solid #0089b7;
}

Answer 1

您有background-image作为属性，但是您为其设置了所有背景值，只需将background代替background-image。

Answer 2

.cSub {    
  background: #00f;    
  background: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -moz-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);    
  background: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -webkit-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);    
  background: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -o-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);   
  background: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, -ms-linear-gradient(-45deg, #0088b7 0%, #006da4 100%);    
  background: url("../images/header/Down_Arrow.svg") 9px 8px no-repeat, linear-gradient(135deg, #0088b7 0%, #006da4 100%);   
  border-top: 2px solid #0089b7;    
width:200px;    
height:auto    
}

您需要提及宽度和高度才能显示背景。
