在CSS中移動漸變條

我想要一個彩條，另一種顏色移動到這個條上。它應該是這樣的，有白色部分移動：在CSS中移動漸變條

Example bar

我在想什麼，梯度和CSS 3 的anmiation財產，我不想用JS！我想是這樣的：

HTML：

<body> 
    <div class="navbar_line"></div> 
</body>

CSS：

.navbar_line { 
animation: gradient 5s linear infinite; 
} 
@-webkit-keyframes gradient 
{ 

0% {

未完待續......

不管你信不信，它的工作原理！我寫了一個生成這些行的腳本。但它很大，比圖片還大，因此無法使用。

我希望你會找到更好的方法。

html部分很簡單，只需要兩個不同的div。

HTML：

<body> 
    <div class="background"> 
     <div class="movement"></div> 
    </div> 
</body>

CSS：

.movement 
{ 
    background: -webkit-linear-gradient(left, rgba(255, 255, 255, 0) 0%, rgba(0,255,0,0.7) 25%, white 50%, rgba(0,255,0,0.7) 75%, rgba(255, 255, 255, 0) 100%); 
    background: -o-linear-gradient(right, rgba(255, 255, 255, 0) 0%, rgba(0,255,0,0.7) 25%, white 50%, rgba(0,255,0,0.7) 75%, rgba(255, 255, 255, 0) 100%); 
    background: -moz-linear-gradient(right, rgba(255, 255, 255, 0) 0%, rgba(0,255,0,0.7) 25%, white 50%, rgba(0,255,0,0.7) 75%, rgba(255, 255, 255, 0) 100%); 
    background: linear-gradient(to right, rgba(255, 255, 255, 0) 0%, rgba(0,255,0,0.7) 25%, white 50%, rgba(0,255,0,0.7) 75%, rgba(255, 255, 255, 0) 100%); 
    width: 400px; 
    height: 5px; 
    position: relative; 
    -webkit-animation: gradient 6s linear infinite; 
    animation: gradient 6s linear infinite; 
} 
.background 
{ 
    width: 1000px; 
    overflow: hidden; 
    height: 5px; 
    background-color: #070; 
} 
@-webkit-keyframes gradient 
{ 
    0% {left: -400px;} 
    100% {left: 1000px;} 
} 
@keyframes gradient 
{ 
    0% {left: -400px;} 
    100% {left: 1000px;} 
}

背景DIV顯然是爲背景，大小，顏色就是這樣。

第二個div是第二個顏色的漸變div。它用漸變着色。動畫導致div在背景上移動。

就是這樣！試試這裏：http://jsfiddle.net/fgeLnbkm/2/

如果你想定製它，它很安靜，大多數的東西很容易改變，除了從運動div的梯度。

這太棒了。不錯的工作！ – 2014-08-28 18:32:44

更好：使用僞元素來避免[divitis]（http://csscreator.com/divitis）http://jsfiddle.net/teddyrised/fgeLnbkm/3/ – Terry 2014-08-28 21:59:22

而不是線性漸變，你可以使用徑向漸變，在這種情況下，你將只需要5個顏色停止，但不是數百。
而不是百個關鍵幀，你只需要其中三個：0％50％和100％（甚至只有2個）。所有中間值將被內插。
