如何风格SVG< g>元件？ [英] How to style SVG <g> element?

问题描述

我有一些SVG元素在< g> 元素中分组在一起。我只是想要样式< g> 元素来显示元素的分组。像我想给一些背景颜色和边框。

I have some SVG elements grouped together in a <g> element. I just want to style that <g> element to show grouping of elements. Like I want to give some background-color and a border to it. How it would be achieved?

我尝试了填充和 stroke 属性到< g> 元素，但它不工作。怎么可能？提前感谢！

I tried fill and stroke attribute to <g> element, but it doesn't work. How it would be possible? Thanks in advance!

这里范例

<svg width="640" height="480" xmlns="http://www.w3.org/2000/svg">
    <g fill="blue" stroke="2">
            <rect id="svg_6" height="112" width="84" y="105" x="136" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke-width="5" stroke="#000000" fill="#00ff00"/>
        <ellipse fill="#FF0000" stroke="#000000" stroke-width="5" stroke-dasharray="null" stroke-linejoin="null" stroke-linecap="null" cx="271" cy="156" id="svg_7" rx="64" ry="56"/>
    </g>
</svg>

推荐答案

你实际上不能绘制容器元素

但您可以使用foreignObject与SVG，以模拟您需要的内容。

But you can use a "foreignObject" with a "SVG" inside it to simulate what you need.

<svg width="640" height="480" xmlns="http://www.w3.org/2000/svg">
      <foreignObject id="G" width="300" height="200">
        <svg>
          <rect fill="blue" stroke-width="2" height="112" width="84" y="55" x="55" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke="#000000"/>
          <ellipse fill="#FF0000" stroke="#000000" stroke-width="5" stroke-dasharray="null" stroke-linejoin="null" stroke-linecap="null" cx="155" cy="65" id="svg_7" rx="64" ry="56"/>     
        </svg>
          <style>
              #G {
                background: #cff; border: 1px dashed black;
              }
              #G:hover {
                background: #acc; border: 1px solid black;
              }
          </style>
      </foreignObject>
    </svg>
