html - 在 CSS 中缩放响应式 SVG

转载作者：行者123 更新时间：2023-12-04 09:46:08

我想知道如何缩放 SVG 以在每个屏幕尺寸上看起来都不错。这是我所拥有的

作为背景的线性渐变

我需要在上面涂抹 2 个面膜，顶部有空白区域，底部有空白区域

我设法以 320x770 像素的大小重现了我想要的设计，但我正在努力寻找如何使它适合不同的屏幕尺寸或方向。

我创建了一个代码沙箱来展示我的问题(将其打开到 320x770 的新窗口以查看所需的结果)。 https://codesandbox.io/s/blissful-frost-ste6y?file=/pages/index.vue

这是我迄今为止尝试过的:

相对于父级缩放 SVG 在某些时候它变得太大

保持原始尺寸，但我最终在侧面显示渐变

最佳答案

我会首先简化您的代码以考虑多个背景，然后我稍微编辑了您的 SVG 并添加了 preserveAspectRatio="none"允许他们扩展:

main section {
