Question

我们在我们的网站上使用Bootstrap 3并且我在一个新模板上收到了一个请求，其设计中有一些元素并没有真正遵循引导网格。我试图让它发挥作用，但没有成功。

我试图在下面的图片中解释这个问题。任何人都知道如何解决这个问题？

Answer 1

一种选择是使用CSS伪::before元素，它将与col-lg-6一起调整高度。

#main {
    background: lightgreen;
    height: 100vh;
}

#main > .row {
    height: 100vh;
}

.left {
    background: red;
    position: relative;
    top: 50%;
    transform: translateY(-50%);
}

.left:before {
    left: -999em;
    background: red;
    content: '';
    display: block;
    position: absolute;
    width: 999em;
    top: 0;
    bottom: 0;
}
<div class="container" id="main">
    <div class="row">
        <div class="col-lg-6 left">
            ..
        </div>
    </div>
</div>

另一个选择是在内容.container-fluid后面使用绝对位置.container（全宽）作为＆＃34;鬼＆＃34; ...

.abs {
    position: absolute;
    right:0;
    top:0;
    bottom:0;
    z-index: 1;
}

<div class="container">
    <div class="row">
        <div class="col-sm-6">
            <h4>Content</h4>
        </div>
        <div class="col-sm-6">
            <!-- space over image -->
        </div>
    </div>
</div>
<div class="container-fluid abs">
    <div class="row h-100">
        <div class="col-sm-6 h-100">
            <!-- empty spacer -->
        </div>
        <div class="col-sm-6 right">
            <img src="//placehold.it/1000x400">
        </div>
    </div>
</div>

Answer 2

以下是解决方案的变体。您需要创建绝对定位div，将其包含在col-xs-6中，但此容器应具有position: static 至于屏幕宽度1200px以及更多容器宽度是1170px，您可以为浮动div计算padding-left：padding-left: calc((100% - 1170px) / 2);

.blk {
    background: lightgreen;
    width: 50%;
    position: absolute;

}
.container {
    background: tomato;
    height: 100vh;
    padding: 40px 0;
}
@media only screen and (min-width: 1200px) {
 .cell {
    position: static;
 }
 .blk {
    left: 0;
    right: 50%;
    padding-left: calc((100% - 1170px) / 2);
 }
}

<div class="container">
<div class="row">
    <div class="col-lg-6 cell">
        <div class="blk">Lorem ipsum dolor</div>
     </div>
  <div class="col-lg-6">Lorem ipsum dolor</div>
</div>
</div>

Answer 3

我没有真正理解你的意思。这就是我认为你的意思。

<div class="container" style="width:1200px">
    <div class="row">
        <div class="col-lg-6">

        </div>
    </div>
</div>

DEMO：http://jsfiddle.net/jayjay95/ybx97y2c/
（如果这是您想要的，请将容器宽度200px更改为1200px，将col-xs-6更改为col-lg-6。

您可以使用以下代码：

<!DOCTYPE html>
  <html class=" desktop landscape" lang="en">

Answer 5

在元素上，添加以下CSS：

width: calc(100% + 30px); //full width plus 15px padding on each side margin-left: -15px; //center element

Answer 6

我就是这样解决问题的。我认为这会有所帮助。

f <- c('12', '24', '36', '48', '60')
for(i in f){
   # // construct the object name
   nm1 <- paste0('verifdata', i)
   # // get the value of object
   tmp <- get(nm1)
   # // find the location of the columns
   i1 <- match(c("StormTotalSnow", "SnowAmt05PrcntlF"), names(tmp))
   # // change the names to new names
   names(tmp)[i1] <- paste0(c("StormTotalSnow", "SnowAmt05PrcntlF"), i)
   # // assign to update the objects in global env
   assign(nm1, tmp)

   }

Answer 7

如果您使用网格并将其绝对放置在主要内容的后面，则可以使背景网格与前景网格完全相同。然后，您可以使用伪元素定位图像以拉伸到屏幕边缘。

.first .stretch-right::after {
  background: url('https://i.picsum.photos/id/802/1920/1080.jpg?hmac=6P9kWTyEU0oX0KcmjlRcGZwNc5Jb27w2_qqtsqQz-fg') no-repeat;
}
.second .stretch-left::after {
  background: url('https://i.picsum.photos/id/802/1920/1080.jpg?hmac=6P9kWTyEU0oX0KcmjlRcGZwNc5Jb27w2_qqtsqQz-fg') no-repeat;
}
.stretch-right::after {
  content: '';
  background-size: cover !important;
  background-position: center center !important;
  right: 0;
  height: 100%;
  position: absolute;
  left: 0;
}
@media (min-width: 1140px){
  .stretch-right::after {
    right: calc((-1%) - ((100vw - 1140px) / 2));
  }
}
.stretch-left::after {
  content: '';
  background-size: cover !important;
  background-position: center center !important;
  right: 0;
  height: 100%;
  position: absolute;
  left: 0;
}
@media (min-width: 1140px){
  .stretch-left::after {
    left: calc((-1%) - ((100vw - 1140px) / 2));
  }
}
