【问题描述】：
我正在尝试制作一个仅使用屏幕空间的网站。
徽标位于页面的中上部，全宽导航栏，然后是 2 行，每行 3 张全宽图像，将在分辨率允许的情况下进行裁剪。 Here is the sketch.
我的问题是设置为 col-sm-4 div 的背景的图像没有显示，并且它们的高度设置为 0px（我试过！重要）。代码对 % 或背景大小的高度没有反应 - 封面。如何在每个分辨率下以相同的高度精确地在页面上制作这些图像？

-
My problem is that I can't get work the images更多解释和功能代码你必须展示。 :) 我不明白你的问题。 -
"因为它们的高度设置为 0，我无法更改。" 抱歉，您能详细说明一下吗？
-
您在所有高度中都使用 %，因此至少有一个父级应该有一个高度，否则它们都将保持为 0
-
看起来像you've already asked a similar question。请不要发布重复的问题。而是编辑现有问题，并在问题得到回答时接受答案。
