使用從alpha到一種顏色的CSS3線性漸變

Question

我正在尋找一種方法來從「無」（alpha）到一個定義的顏色：＃e6a015。我無法在谷歌或這裏找到它，有人可以告訴我如何做到這一點？

Answer 1

您可以使用RGBA顏色與阿爾法爲零

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%);
