SVG线全屏尺寸

问题描述 投票：3回答：2

我试图实现下面的图像：

从每个圆圈出来的线条无限旋转（通过css关键帧不难实现）我尝试使用100个div并且每个旋转10度但是未能达到我的需要。所以我想到svg和我做了一些事情，但它根本不起作用，线条不全屏。小提琴。

我会认为圆是主要元素，我会使用一个伪元素，我用旋转的SVG背景填充所有这些线。

为了使事情变得更容易，您可以依赖JS来生成背景代码：

var all = document.querySelectorAll('.circle');

for (var i = 0; i < all.length; i++) {
  var c = all[i].getAttribute("data-color");
  var s = parseInt(all[i].getAttribute("data-step"));
  var b = 'url(\'data:image/svg+xml,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 200" height="5000" width="5000"><line x1="100" y1="0" x2="100" y2="200" stroke="' + c + '" stroke-width="0.05" /></svg>\')';
  var end = 180 / s;
  for (var j = 1; j < end; j++) {
    b += ',url(\'data:image/svg+xml,<svg style="transform:rotate(' + s * j + 'deg)" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 200 200" height="5000" width="5000"><line x1="100" y1="0" x2="100" y2="200" stroke="' + c + '" stroke-width="0.05" /></svg>\')';
  }
  all[i].style.setProperty("--b", b);
  all[i].querySelector('span').style.setProperty("background", c);

}

  overflow: hidden;

  width: 100px;
  position:absolute;

我的想法最初来自于考虑伪元素，但是因为你每个元素只有2个（::before和::after），它永远不会给你想要的结果。

所以（不幸的是）我们将不得不使用很多div，但我提出的需要最少量的div（如果我们不使用伪元素）并且如果你想或多或少需要很容易改变线条，或线条之间或多或少的空间。

为了实现这一目标而不手动编写每一行，我使用了Text Pastry包进行Sublime。
