使用从alpha到一种颜色的CSS3线性渐变

Question

我正在寻找一种方法来从“无”（alpha）到一个定义的颜色：＃e6a015。我无法在谷歌或这里找到它，有人可以告诉我如何做到这一点？

Answer 1

您可以使用RGBA颜色与阿尔法为零

background-image: -ms-linear-gradient(top left, rgba(230,160,21,0) 0%, rgb(230,160,21) 100%); 

/* Mozilla Firefox */ 
background-image: -moz-linear-gradient(top left, rgba(230,160,21,0) 0%, rgb(230,160,21) 100%); 

/* Opera */ 
background-image: -o-linear-gradient(top left, rgba(230,160,21,0) 0%, rgb(230,160,21) 100%); 

/* Webkit (Safari/Chrome 10) */ 
background-image: -webkit-gradient(linear, left top, right bottom, color-stop(0, rgba(230,160,21,0)), color-stop(1, rgb(230,160,21))); 

/* Webkit (Chrome 11+) */ 
background-image: -webkit-linear-gradient(top left, rgba(230,160,21,0) 0%,rgb(230,160,21) 100%); 

/* W3C Markup, IE10 Release Preview */ 
background-image: linear-gradient(to bottom right, rgba(230,160,21,0) 0%, rgb(230,160,21) 100%);
