改變梯度hr的線性值

Question

我有改變<hr/>到漸變類型的CSS代碼，

<hr class="style-one" /> 

.....

hr.style-one 
{ 
border: 0; 
height: 1px; 
background-image: -webkit-linear-gradient(left, rgba(0,0,0,0), rgba(0,0,0,0.75), rgba(0,0,0,0)); 
background-image: -moz-linear-gradient(left, rgba(0,0,0,0), rgba(0,0,0,0.75), rgba(0,0,0,0)); 
background-image: -ms-linear-gradient(left, rgba(0,0,0,0), rgba(0,0,0,0.75), rgba(0,0,0,0)); 
background-image: -o-linear-gradient(left, rgba(0,0,0,0), rgba(0,0,0,0.75), rgba(0,0,0,0)); 
} 

但是樣式生成（白 - 黑 - 白色）漸變，你可以檢查它Here :)
我怎樣才能改變這個漸變（黑色 - 白色）？
