在元素之间添加边距会导致元素开始换行 [英] Adding margins between elements cause element to start a new line
本文介绍了在元素之间添加边距会导致元素开始换行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我创建了自己的响应式网页设计网格，包含12列（如引导程序），并且此网格中的每一行都占用100％的网格。在我的html文件中，我有三个部分，其中每个部分占页面的33.33％，总计100％。当我尝试在这些部分之间添加边距时，线条中的最后一部分跳转到新线条。我知道引导程序使用偏移类来解决这个问题，但我试图用我自己的响应式网页设计网格来实现解决方案。
I created my own responsive web design grid with 12 columns (like bootstrap) and every row in this grid takes a 100% of the grid. In my html file I have three sections of which every section takes 33.33% of the page, 100% in total. When I try to add margins between those sections, the last section in line jumps to new line. I know that bootstrap uses offset classes to solve this issue, but I'm trying to implement a solution with my own responsive web design grid.

推荐答案
是的，您需要使用 calc（）
- 20px in width：calc（33.33％ - 20px） ; 来自10px的边距，部分的每边10个
The - 20px in width: calc(33.33% - 20px); comes from your margin of 10px, 10 on each side of the section
