我们的 Angular (v7) 应用程序有一个启动动画，它基本上显示了一个嵌入到 index.html 中的旋转轮(CSS 动画)，因此它会在页面加载时立即显示。
这工作正常，但是每加载 ~4 个页面，缩放级别就会轻微闪烁(我在 Windows 10 上使用最新的 Chrome)，这意味着保存“启动消息”的方形 div 从一个尺寸开始，然后下降约 5% 的大小。它发生得非常快，从静态 HTML 内容呈现到 View 的那一刻到呈现 Angular View 之前大约一秒钟。看起来某些渲染引擎正在延迟加载并且出现问题(？)
会不会是 Angular 正在改变页面加载时的缩放/平移系数？

最佳答案
box-sizing 由我们自己的代码设置....这会触发 div 大小的微小变化
