css - Bootstrap 中奇怪的 CSS 效果。在容器 div 中显示大量内容 div 时意外缩进

Question

我正在使用 Bootstrap 作为我和我的 friend 正在进行的元素的 CSS 框架(因此是 D&D 主题)。我有一个页面，我们在其中显示特定用户的 D&D Angular 色。当在页面上显示这些字符时，每行应该有四个(span4's in a row-fluid)。问题是从第二行开始有一个奇怪的缩进(参见附加的 fiddle )。

我一直在 Chrome 中使用“检查组件”，但我似乎无法理解是什么导致了这种情况。

希望我能稍微解释一下这个问题:)

下面粘贴了主要的“容器”(本质上是 ):

  <div class="container"><div class="row">
    <div class="span12">
        <h3 class="mycharacters">My characters</h3>
        <a class="btn btn-success btn-small pull-right">
            <i class="icon-plus-sign icon-white"></i> Add character
        </a>
    </div>

Answer 1

该缩进来自这样一个事实，即您排列的 div 堆栈超出了每行 12 列的网格限制，因此超过 12 列标记的网格元素按设计缩进。您可以通过为每个 .row-fluid (4x3=12) 仅排列 3 个 .span4 div 或使用一些 css 魔法定位第四个网格元素并删除边距来避免这种情况，像这样:

CSS

.row-fluid > .span4:nth-child(4) {
    margin-left:0;
}

当然，nth-child 选择器在旧版浏览器(如 IE7-8)中不受支持，但如果您想扩展支持，可以将 CSS 替换为一些 jQuery。
