引导网格中的容器响应正确吗？

Mar*_*ark 5 html css twitter-bootstrap twitter-bootstrap-3

所以我有3个盒子需要具有特定的高度和宽度,并将它们设置在bootstrap中作为子元素.在全视图中看起来很好:

但是,当窗口调整大小时,框会向左移动而不是浮动在背景图形的中间.此外,标题文本(黄色)丢失其上填充:

认为"响应性"正在接管,但无法确定它,我希望你们中的一些人可以提供帮助.

我的HTML是这些:

<div class="container">
    <div class="claimHead col-md-12">
        <div class="submitHeader" style="margin-top: 60px; margin-bottom: 60px; margin-left: 30px;">
            <h1 style="font-size: 36px;">Claim Submission Tool</h1>
            <p style="font-size: 18px;">Filing claims has never been easier, it's a simple as 1, 2, 3</p>
        </div>
        <div id="stepsContainer">
            <div class="col-md-4 stepsBox">

关于我在这里可以做什么以及在哪里检查的任何想法？我也在这个CSS的顶部使用Bootstrap 3,但是我没有看到它导致盒子向右移动的位置.

非常感谢.

默认情况下，列向左浮动，并且因为您在列 ( .claimSteps) 内使用固定的高度/宽度，所以一旦中列折叠，它们别无选择，只能向左对齐，因为它们无法占据 100% 的较小视口。

标题对齐主要取决于您的 HTML 结构。

请注意，您应该考虑更改的一个区域是您正在创建的框的宽度。它太宽并且开始破裂/溢出，因为它是固定的。如果你可以减少它，你应该（我的例子反映了这一点，但可以很容易地改回默认宽度。）

盒子的固定尺寸也在 400px 左右发挥作用。在第二个示例中，我使盒子变得灵活，因此它可以在所有视口中正常工作。请参阅 400 像素以下视口上的示例 1 和 2。

以下是一些可能有帮助的示例。
