我目前正在设计一个基本网站，然而，在几乎完成了我的 CSS 之后，我发现当我在另一台计算机上打开网页时，它看起来不同，而且不仅取决于网络浏览器，它在不同方面看起来也不同。
因此，我不确定这是否是浏览器或分辨率兼容性的问题，所以我的问题是谁能告诉我问题出在哪个领域（可能两者都有），也许可以就我可以解决问题的方向提出建议。
以下是在我的笔记本电脑（分辨率为 1600x900）和家庭电脑（分辨率为 1440x900）的四个“主要”浏览器上运行的网页截图在线相册的链接。此外，如果页面被调整大小或放大，那么事情就会开始移动。

提前感谢您的任何帮助或建议，如果您希望我提供任何进一步的信息，请说出您希望看到的内容。
