在网格系统之外移动元素

Question

我正在用 bootstrap 开发一个 tumblr 主题，我想在 header 旁边为用户的个人资料图片留出一个不错的大区域。这里的问题是，bootstrap 的网格格式非常紧凑，我看不到任何我想要的空间：

看到那个红色的东西了吗？我想将它移动到蓝色箭头所指的位置。我试过扩展容器，将红色圆圈设置为向左浮动，并给它 margin-bottom:100%，但这将所有内容都推到了页面之外。

这是我的 css 和 HTML 供参考，有问题的项目标有 class "talkbubble":

CSS

//Media Queries
@media (min-width: 1200px){
    .container {
        width: 800px;
    }
}
@media (min-width: 992px){
    .container {
        width: 800px;
    }
}


//Header Edits

    margin-bottom: 0px;
    h1{
        color: red;
    }

Answer 1

绝对位置是解决您问题的正确方法。但是你必须使用其他属性而不是 float:
- top
- bottom
- left
- right

For absolutely positioned elements (those with position: absolute or position: fixed), it specifies the distance between the margin edge of the element and the edge of its containing block.

For relatively positioned elements (those with position: relative), it specifies the amount the element is moved below its normal position.

您可以将此属性直接应用于气泡而不是 before: 伪元素。
在 CSS 中使用 /* */ 而不是 // 进行评论。例如：

/* iconbubble */
.talkbubble {
  position: absolute;
  top: 100px;
  left: 20px;
  z-index: 20;
}

Answer 2

见this fiddle

诀窍是这样的：

<div class="container-fluid">
  <div class="row">
    <div class="col-md-3">
      ...your image markup here...
    </div>
    <div class="col-md-9">
      ...
    </div>
  </div>

我从 md 开始就设置成这样了。您可能希望对宽度较低的图像列使用 hidden-*，因为从设计的角度来看，您所做的事情在移动宽度下看起来很奇怪。
