SVG动画：描边/边框不完整

我有一个公司的标志我试图让外部（方形）边框动画进出。我目前使用dasharray和dashoffset属性来帮助我做。 Here是一篇解释它的文章。SVG动画：描边/边框不完整

我有它的工作，但边界似乎不是从一开始就开始，或完成动画到最后。

Here是CodePen与我的工作示例

这里是我的代码：

的问题是，你不能设置笔画对齐到内部。

作为一种解决方法，您可以使用内边框矩形。笔画宽度需要翻倍。

试图在以下codepen

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 812.73 388.23"> 
    <title>Asset 3 1</title> 
    <symbol id="inner-border-rect"> 
     <rect id="perimeter" x="0" y="0" width="100%" height="100%" fill="none" stroke="#3cd52e" stroke-width="44"/> 
    </symbol> 
    <use xlink:href="#inner-border-rect" x="11" y="11" width="790.73" height="366.23"> 
</svg>

也看看那个：Can you control how an SVG's stroke-width is drawn?

希望它能帮助。

太棒了，谢谢一堆！ – ghall

我认为问题源于SVG viewbox属性和rect尺寸之间的冲突。

如果您要更换SVG viewbox与height和width性能

<svg xmlns="http://www.w3.org/2000/svg" width="801.73" height="366.23">

并删除x和y坐标矩形。

<rect id="perimeter" width="801.73" height="366.23" fill="none" stroke="#3cd52e" stroke-width="22"/>

你会得到一排排。

我还调整了stroke-dashoffset和stroke-dasharray值以确保边缘排列整齐。

#perimeter { 
    stroke-dasharray: 2333.919921875; 
    stroke-dashoffset: 2333.919921875; 
}

codepen

#perimeter { 
 
    stroke-dasharray: 2333.919921875; 
 
    stroke-dashoffset: 2333.919921875; 
 
    animation: dash 5s linear alternate infinite; 
 
} 
 

 
@keyframes dash { 
 
    from { 
 
    stroke-dashoffset: 2333.919921875; 
 
    } 
 
    to { 
 
    stroke-dashoffset: 0; 
 
    } 
 
}
