如何确保我的 CSS 内容完美适合 Web 浏览器窗口？

我面临的问题是，尺寸为宽度 1917.00 x 高度 850.00 的内容超出了笔记本电脑 Chrome 浏览器窗口的边界，需要我滚动才能查看它。有趣的是，在另一台相同型号和浏览器的笔记本电脑上，内容完全适合，无需滚动。

为了缓解这个问题，我发现将笔记本电脑浏览器的缩放级别降低到 75% 可以解决该问题，从而使内容能够紧贴窗口而无需滚动条。

现在，我的问题是：在 CSS 中的哪里可以将尺寸统一调整为 75%，以确保内容完美适合每个笔记本电脑型号的浏览器窗口？我的主要目标是完全显示内容而不需要使用滚动条。

我也不希望按钮文本大小视图变小。

这是我的 CSS 代码：

在 HTML 代码中，将

meta

标签添加到

header

:

<meta name="viewport" content="width=device-width, initial-scale=1.0">

这应该让浏览器知道如何根据设备宽度缩放页面。
