html - Ios Iphone 6 Divs 过度扩展屏幕

Question

我有 3 个 div：

Main Container 
A header
A search bar.

我用最少的代码让所有的 CSS 流畅且响应迅速。

但是经过测试，我发现了 1 个小问题。

在桌面上 一切看起来都很好，并且反应灵敏且准确

但是一旦我在我的 iPhone 上加载页面（其他都很好）

因为主体的最小宽度为 450 像素，所以屏幕宽度溢出而不适合 iPhone 屏幕，我添加了视点元标记，最初修正了我的问题并缩小了屏幕以适合 iphone，但那是最小宽度屏幕的适配。

现在我需要 450px 的最小宽度来适应某些内容，但现在它稍微超出了屏幕的宽度，而不是正确地适应。
