欢迎来到令人惊叹的Web开发世界.

由于您未提供任何代码或屏幕截图，因此我无法建议您对问题进行有保证的修复.因此，我将尝试通过传送将自己转移到您的计算机上，并看一下代码.但是既然是周末，我现在有点懒了.
到那时我将提供一些通用的解决方案来编写与浏览器兼容的CSS

Welcome to the amazing world of web development.

Since you have not provided any code or screenshots,I cannot suggest you a guarenteed fix for your issues. So I will try to transfer myself to your machine via teleportation and will have a look at the code. But since this is the weekend , I am a bit lazy now.
Till then I am providing some generic solutions to write browser compatible CSS
