在响应式布局中设置元素高度? [英] Setting element height in responsive layout?
问题描述
一般来说,什么标记和 CSS 会在响应式设计中创建一个基于百分比的高度的元素?如何构建 2 列(固定- Fluid) Layout with Twitter Bootstrap? 展示了如何创建两个 100% 高度的列,但这会破坏高度 <100%.
具体来说,我有一个带有项目列表的侧边栏 div,它可能很短(空)或很长(overflow: auto
).但是因为没有父元素有固定的高度,height: 20%;
不起作用.如何在保持响应式设计的同时为侧边栏提供流畅的高度?
通常在父容器上有一个流体填充底部可以解决这个问题.

标记:
<div class="content">content</div>
CSS:
.obj-wrapper {位置:相对;宽度:50%;填充底部:40%;高度:0;溢出:隐藏;}.内容 {位置:绝对;宽度:100%;高度:100%;背景:红色;}
Generally, what markup and CSS will create an element with a percentage-based height in a responsive design? How to build a 2 Column (Fixed - Fluid) Layout with Twitter Bootstrap? shows how to create two 100% height columns, but this breaks for heights < 100%.
Specifically, I have a sidebar div with a list of items, which may be short (empty) or long (overflow: auto
). But because no parent elements have a fixed height, height: 20%;
does not work. How can I give the sidebar a fluid height while maintaining a responsive design?
Usually having a fluid padding-bottom on the parent container solves this problem.
