使div在响应式设计中从右到右

时间：2019-01-07 16:11:36

标签： css html5 twitter-bootstrap responsive-design

我正在使用this left sidebar。我还在右侧添加了一个div，左侧填充了侧边栏的大小。

现在，如果我切换到较小的屏幕，则侧边栏会排在最前面（这是理想的结果），但我的div会保留填充，而内容位于屏幕的右端。

我该如何使div跳到边栏下方并保持一定的高度。甚至有可能吗？

有可能吗？

是的。只需覆盖padding-left属性。由于#content是导航栏（.nav-side-menu）的直接同级，因此您可以使用adjacent sibling combinator（+）并将样式应用于目标屏幕。

@media (max-width: 767px) {
  .nav-side-menu {
    position: relative;
    width: 100%;
    margin-bottom: 10px;
  }

  .nav-side-menu + #content {
    padding-left: 0;
  }

  /* the rest of the styles*/
}

从代码的外观来看，您似乎正在使用Bootstrap版本3，该版本具有内置功能，可根据屏幕大小显示或隐藏项目，这可能会对您有所帮助。 You can read more about that here。

或者您也可以添加自己的媒体查询，以在屏幕宽度达到特定大小时删除填充。也许是这样的：

import numpy as np
import pandas as pd
from io import StringIO
# alternatively try `import StringIO`

returns_datatext = StringIO("""
    DateTime     │  Asset 1  │  Asset 2  │  Asset 3
2015-04-09 07:00 │ -0.000959 │ -0.000207 │ -0.000233
2015-04-09 08:00 │ -0.004003 │  0.000169 │  0.001221
2015-04-09 09:00 │ -0.000700 │ -0.000070 │ -0.000096
2015-04-09 10:00 │ -0.000812 │ -0.000289 │  0.000177
2015-04-09 11:00 │ -0.000030 │ -0.000168 │ -0.000315
""")
returns_df = pd.read_table(returns_datatext, index_col=[0], parse_dates=True, sep='│')

weights_datatext = StringIO("""
Start of weights │ Asset 1 │ Asset 2 │ Asset 3
2015-03-01       │       1 │       0 │       0
2015-04-01       │   0.023 │  0.8733 │  0.1037
2015-05-01       │       1 │       0 │       0
2015-06-01       │  0.0477 │  0.8278 │  0.1245
""")
weights_df = pd.read_table(weights_datatext, index_col=[0], parse_dates=True, sep='│')
