如何更改SVG图像中的背景颜色？

这是一个SVG图像的例子，我需要将背景颜色从当前白色变为透明（或黑色）。
到目前为止，我只能改变前景色。如何更改SVG图像中的背景颜色？

试图修改pagecolor没有成功。

我该怎么做，可能不使用CSS？

您的SVG没有设置背景颜色，所以它应该已经透明。应该没有什么你需要做的。 –

Inkscape中容易产生严重臃肿的文件。这里是为你清理的版本：

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 90 90"> 
 
    <defs> 
 
    <mask id="chain"> 
 
     <rect x="4" y="28" width="34" height="34" fill="black" stroke="white" stroke-width="7" rx="7" /> 
 
     <rect x="52" y="28" width="34" height="34" fill="black" stroke="white" stroke-width="7" rx="7" /> 
 
     <rect x="21" y="39" width="48" height="12" fill="white" stroke="black" stroke-width="4" /> 
 
    </mask> 
 
    </defs> 
 
    
 
    <!-- Uncomment this for manual background --> 
 
    <!--rect fill="#000" width="90" height="90" /--> 
 
    
 
    <rect fill="#ff0" width="90" height="90" mask="url(#chain)" /> 
 
</svg>

你会发现，不仅比你的文件，这个显著更小，它也更容易看到发生了什么事情：我使用两个圆角正方形和一个矩形链接，使用一个遮罩来剪切形状。然后，用形状作为掩模来填充颜色以获得结果。

这没有定义背景颜色。如果作为图像文件使用，它将透明地显示它后面的任何背景。或者您可以取消注释指示的行以在图标上强制执行背景。

试试这个

style="background-color: #000;"在线添加到<svg>

是的，它的工作原理。是否有可能将其设置为透明？ – Pietro

@Pietro是的，你可以将属性设置为透明'style =“background-color：transparent;”'你可以通过编辑codepen中的例子来赋予'body'不同的颜色（'body {background {color} ：red; }'） –
