Css过渡梯度为纯色

我目前在创建从渐变到纯色的过渡方面非常失败。另外,由于我的渐变,我似乎无法看到我的背景图像与右侧对齐。

这是我的代码:

input {
    width: 306px;
     height:27px;
    font-size:12px;
    font-family: Arial,Helvetica,sans-serif;
    padding: 1px 30px 1px 9px;
    color: #767676;
    font-weight: normal;
    margin: 3px 0;
    -webkit-border-radius: 3px;
    -moz-border-radius: 3px;
     border-radius: 3px;
    border:1px solid #e5e5e5;
    background-image:url('http://i.imgur.com/9hdsg.png');
    background-position:right;
    background-repeat:no-repeat;

    -moz-transition-property: width, background-color;
  -webkit-transition-property: width, background-color;
  -o-transition-property: width, background-color;
  transition-property: width, background-color;

  -moz-transition-duration: 0.5s, 0.5s;
  -webkit-transition-duration: 0.5s, 0.5s;
  -o-transition-duration: 0.5s, 0.5s;
  transition-duration: 0.5s, 0.5s;

  }



input:focus {
  width: 535px;
  background-color:#ffffff;
}

谢谢大家:)

  1. 要使多个背景工作,您需要在一行中声明它们: background: url(path/to/image), linear-gradient(...) - 第一个是最接近的,因此它涵盖了其他人。
  2. 将渐变设置为纯色,使渐变为元素的两倍(或更长),因此50%使用25%等。
  3. 背景位置也在一行中声明,同样重复。在你的情况下:

    background-size: 27px 29px, 100% 200%; // first image, then gradient twice as high
    background-repeat: no-repeat, repeat; // don't repeat image, repeat gradient
    
  4. 将渐变设置为纯色 - 使用转换将背景位置从background-position: 0 50%, 0 0;更改为background-position:0 50%, 0 100%;

  5. upadted your fiddle,但没有尝试使用过滤器或旧的webkit语法。
