css - SVG 图标动画留下像素间隙

标签 css svg css-animations frontend pixel

我正在使用 CSS 制作 SVG 动画，我注意到在我的线条画动画中，任何 SVG 矩形(#clipboard-border 和 #clipboard-clip-border)笔划总是会排除左上角的一点 Angular ，这使它成为一个不完整的矩形。

我试过在 CSS 中调整 stroke-dasharray 和 stroke-dashoffset 测量值，以及在 SVG 代码中调整大小和像素协调，但看起来都不是问题。帮忙？

最佳答案

只需将 stroke-linecap: square; 添加到 SVG 对象的 CSS 声明即可。

svg {
  display: inline-block;
  width: 120px;
  margin: 3% auto;
  padding: 0px 100px;
  stroke-linecap: square;  /* <-- Add this */
}

示例:

这是一个有两条路径的 SVG(开放的，而不是封闭的)。用“butt”线结尾绘制的路径在顶 Angular 有点缺失，但另一条路径(用“square”线结尾绘制)没有这个问题。

<svg width="250" height="100" viewBox="0 0 250 100">
  <path d="M10 10h80v80h-80v-80" style="stroke:#000; stroke-width:10px; fill:none; stroke-linecap: square;"/>
  <text x="50" y="70" text-anchor="middle">Square</text>
  <path d="M160 10h80v80h-80v-80" style="stroke:#000; stroke-width:10px; fill:none; stroke-linecap: butt;"/>
  <text x="200" y="70" text-anchor="middle">Butt</text>
 </svg>

附言我喜欢你的作品，但下次请考虑制作 minimal, complete and verifiable example来说明问题。这样人们就不必费力地浏览大量代码来发现问题所在:-)
