Css 覆盖SharePoint的square.gif和setrect.gif

在SharePoint 2007网站集的自定义品牌中，我需要更改项目符号图像。SharePoint 2007不使用标记，而是使用表和图像，如下所示：

<tr>
    <td class="ms-vb" style="padding-bottom: 5px;"><img alt="" src="/_layouts/images/square.gif">&nbsp;</td>
    <td class="ms-vb" style="padding-bottom: 5px; padding-left: 5px;">
        <a href="http://stackoverflow.com" onfocus="OnLink(this)">stackoverflow</a>
    </td>
</tr>

有什么想法吗？

试试：

td.ms-descriptiontext img,
td.ms-vb img
{
    background:transparent url("/_layouts/images/myproject/bullet.gif") no-repeat top left;
    display: block;
    height: 0;
    padding: 5px 5px 0 0;
}

尝试边距而不是填充

我对javascript做了一项工作：查找img标记并替换它们的源代码：

  <script language="javascript" type="text/javascript">
var arrElements = document.getElementsByTagName("img");
for (var i=0; i<arrElements.length; i++) {
        //get pointer each image element:
        var element=arrElements[i];
        //check for a source with /images/square.gif from this site:
        if (element.getAttribute('src') == "http://www.MY-SITE-NAME.com/_layouts/images/square.gif") {
            //found... change it's src to our new image:
            element.setAttribute('src', 'http://www.MY-SITE-NAME.com/MY-LOCATION/MY-CUSTOM-BULLET.gif');
        }
    }

我有。边距随图像移动背景图像，如果宽度为0，则将其隐藏，如果宽度>0，则会被图像遮挡。是的，javascript可以工作。不幸的是，我仅限于使用css。Javascript不是一个选项。

td.ms-descriptiontext img,
td.ms-vb img
{
    background:transparent url("/_layouts/images/myproject/bullet.gif") no-repeat top left;
    display: block;
    height: 0;
    padding: 5px 5px 0 0;
}

  <script language="javascript" type="text/javascript">
var arrElements = document.getElementsByTagName("img");
for (var i=0; i<arrElements.length; i++) {
        //get pointer each image element:
        var element=arrElements[i];
        //check for a source with /images/square.gif from this site:
        if (element.getAttribute('src') == "http://www.MY-SITE-NAME.com/_layouts/images/square.gif") {
            //found... change it's src to our new image:
            element.setAttribute('src', 'http://www.MY-SITE-NAME.com/MY-LOCATION/MY-CUSTOM-BULLET.gif');
        }
    }
