Question

在问了很多问题之后，我仍然对我的问题应该是什么感到困惑

当我将 CSS 添加到我的 SVG 时出现此错误：

style.css
* {margin:0; padding:0}
body {font:11px/1.5 Verdana, Arial, Helvetica, sans-serif; background:#FFF}
#text {margin:50px auto; width:500px}
.hotspot {color:#900; padding-bottom:1px; border-bottom:1px dotted #900; cursor:pointer}

#tt {position:absolute; display:block; background:url(images/tt_left.gif) top left no-repeat}
#tttop {display:block; height:5px; margin-left:5px; background:url(images/tt_top.gif) top right no-repeat; overflow:hidden}
#ttcont {display:block; padding:2px 12px 3px 7px; margin-left:5px; background:#666; color:#FFF}
#ttbot {display:block; height:5px; margin-left:5px; background:url(images/tt_bottom.gif) top right no-repeat; overflow:hidden}

为什么会出现这个错误？

我遵循这个建议：

if i want to add CSS where would i paste it?

Answer 1

如果您只是想添加 CSS，您可以在您引用的问题链接的文档中查看示例。

http://www.w3.org/TR/SVG/styling.html#StylingWithCSS

这是他们提供的嵌入式样式表的示例：

<style type="text/css"><![CDATA[
      rect {
        fill: red;
        stroke: blue;
        stroke-width: 3
      }
    ]]></style>

以及链接版本：

<?xml-stylesheet href="mystyle.css" type="text/css"?>

有关完整示例，请参阅文档。

所以嵌入你的可能看起来像这样：

<style type="text/css"><![CDATA[

* {margin:0; padding:0}
body {font:11px/1.5 Verdana, Arial, Helvetica, sans-serif; background:#FFF}
#text {margin:50px auto; width:500px}
.hotspot {color:#900; padding-bottom:1px; border-bottom:1px dotted #900; cursor:pointer}

#tt {position:absolute; display:block; background:url(images/tt_left.gif) top left no-repeat}
#tttop {display:block; height:5px; margin-left:5px; background:url(images/tt_top.gif) top right no-repeat; overflow:hidden}
#ttcont {display:block; padding:2px 12px 3px 7px; margin-left:5px; background:#666; color:#FFF}
#ttbot {display:block; height:5px; margin-left:5px; background:url(images/tt_bottom.gif) top right no-repeat; overflow:hidden}


]]></style>
