Question

我正在使用 cs3pie 并遇到一些问题。它正在工作，但不是 border-radius 160 它需要 4 。我该如何解决。

/* Buttons and button links */
    input[type=submit],
    .actions ul li a,
    .actions a {
        font-weight:normal;
        padding: 4px 8px;
        background:  #FDC00D; 
        background-image: -webkit-gradient(linear, left top, left bottom, from(#FDC00D), to(#F68C1E));
        background-image: -webkit-linear-gradient(top, #FDC00D, #F68C1E);
        background-image: -moz-linear-gradient(top, #FDC00D, #F68C1E);
        background-image: -ms-linear-gradient(top, #FDC00D, #F68C1E);
        background-image: -o-linear-gradient(top, #FDC00D, #F68C1E);
        background-image: linear-gradient(top, #FDC00D, #F68C1E);
        -pie-background: linear-gradient(#FDC00D, #F68C1E); /*PIE*/
        color:#333;
        border:1px solid #F69C1E;
        text-decoration: none;
        text-shadow: #ccc 0px 1px 0px;
        min-width: 0;
        -moz-box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.3), 0px 1px 1px rgba(0, 0, 0, 0.2);
        -webkit-box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.3), 0px 1px 1px rgba(0, 0, 0, 0.2);
        box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.3), 0px 1px 1px rgba(0, 0, 0, 0.2);
        -webkit-user-select: none;
        user-select: none;
    }
    .actions ul li a:hover,
    .actions a:hover {
        background:  #FDC00D; 
        border-color: #acacac;
        text-decoration: none;
    }
    input[type=submit]:active,
    .actions ul li a:active,
    .actions a:active {
        background: #F68C1E;
        background-image: -webkit-gradient(linear, left top, left bottom, from(#F68C1E), to(#FDC00D));
        background-image: -webkit-linear-gradient(top, #F68C1E,#FDC00D);
        background-image: -moz-linear-gradient(top, #F68C1E,#FDC00D);
        background-image: -ms-linear-gradient(top, #F68C1E,#FDC00D);
        background-image: -o-linear-gradient(top, #F68C1E,#FDC00D);
        background-image: linear-gradient(top, #F68C1E,#FDC00D);
        -pie-background: linear-gradient(#F68C1E,#FDC00D); /*PIE*/

        text-decoration: none;
    }

    input[type=submit],.actions a {
        -webkit-border-radius: 4px;
        -moz-border-radius: 4px;
        border-radius: 4px;
        position:relative;
        z-index: 0;
    }

    /**  Actions  **/
    .actions ul {
        margin: 0;
        padding: 0;
    }
    .actions li {
        margin:0 0 0.5em 0;
        list-style-type: none;
        white-space: nowrap;
        padding: 0;
    }

    .actions ul li a {
        display: block;
        clear: both;    
        -webkit-border-top-right-radius: 161px;
        -webkit-border-bottom-right-radius: 161px;
        -moz-border-radius-topright: 161px;
        -moz-border-radius-bottomright: 161px;
        border-top-right-radius: 161px;
        border-bottom-right-radius: 161px;
        position:relative;
        z-index: 0;
    }

    .actions ul li a:before,.actions ul li a.highlight:hover:before {
        content: "\2665" ; 
        font-size: 18px;
        padding-right:3px;
        color: #16224C; 

    }

    .actions ul li a.highlight:before,.actions ul li a:hover:before {
       color: red; 

    }

    .actions ul.subcategory{
        margin-left:10px;
        display: none;
    }
    .actions ul.subcategory li a {}

我是这样用pie的

<script>
$(function() {
    if (window.PIE) {
        $('.actions ul li a, .actions a, input[type="submit"], .success,.message,.cake-error,p.error,.error-message').each(function() {
            PIE.attach(this);
        });
    }
});

</script>

CSS3PIE 只支持速记符号。

摘自 http://css3pie.com/documentation/known-issues/#shorthand

For all CSS properties which PIE parses, only the shorthand versions of those properties will be recognized. For example, while border-radius is supported, the individual longhand border-top-left-radius etc. properties are not.

The reason for this is the same reason URLs are not resolved relative to the CSS file (see above): PIE does not have visibility into where each style property comes from. If there is both a shorthand and a longhand property present, PIE cannot determine the order in which the CSS author specified those properties, nor can it determine the specificity of the selector for each property. It cannot therefore make an informed decision about which property should take precedence.

To avoid making dumb guesses, we have opted to only support shorthand properties. Shorthand was chosen over longhand to keep file size small and avoid tedious repetition.
