即使我将宽度分配给 <div>，文本也会溢出

Question

在示例代码中 - 我给了 box 3 和 box 4 宽度 200px 实际上我没有注意使用这些宽度，但我给了它们颜色，以便您可以更直观地看到我的问题。

问题是我的文本没有被父项 <div> 包含，在方框 3 中设置了（硬编码）像素宽度，尤其是它运行s waaay out to the right in 1 line instead在 <div> 内包装。对于 box 4，我可以理解它正试图延伸到尽头，但如果它再长一点，它又会再次运行在网格之外。所以我缺少一些东西来帮助包装内容。我该如何解决这个问题？

利用word-wrap属性。在您的 .box3 和 .box4 类上添加 word-wrap: break-word;。更多内容 here.
