[英]How to vertically center a button and text inside a div

I currently have a page like this: 我目前有一个这样的页面:

<!DOCTYPE html>

I want the h3 and the button to be vertically aligned in the div , and I've tried setting style to vertical-align:middle but it doesn't work. 我希望h3buttondiv垂直对齐,我尝试将样式设置为vertical-align:middle但它不起作用。 What should I do? 我该怎么办?

EDIT: It seems my original question was unclear. 编辑:似乎我原来的问题不清楚。 I meant that I want the header text and button to appear on the same "line", but to be aligned vertically on that line. 我的意思是我希望标题文本和按钮出现在同一“行”上,但要在该行上垂直对齐。 Right now, I can get them to be on the same line but the text and the button will be aligned by the top edge rather than the center. 现在,我可以让它们在同一条线上但文本和按钮将由顶边而不是中心对齐。

You didn't post your css so I don't know what you're working with. 你没有发布你的CSS,所以我不知道你在做什么。 So here's a quick note: 所以这里有一个快速说明:

NOTE: vertical-align only works for display: table-cell; 注意: vertical-align仅适用于display: table-cell; and display: inline; display: inline; elements (It also applies to ::first-letter and ::first-line ). elements(它也适用于:: first-letter:: first-line )。

Here's a simple solution using display: table; 这是一个使用display: table;的简单解决方案display: table; on the parent and display: table-cell; 在父和display: table-cell; for what you want vertically centered. 为了你想要的垂直居中。

If you want your button centered you have to remove the pull-right class, or you can add another class after it and then override it's css. 如果你想让你的按钮居中,你必须删除pull-right类,或者你可以在它之后添加另一个类,然后覆盖它的css。 (Simple solution, just remove the pull-right class. (简单的解决方案,只需删除pull-right类。

Edit: So you want the button in the same line as your h3 tag right? 编辑:那么你想要与你的h3标签在同一行的按钮对吗?

Well before I show you how to solve this remember that h1-h5 tags are all display: block; 在我告诉你如何解决这个问题之前,请记住h1-h5标签都display: block; elements meaning they will always embed as a new line. 元素意味着它们将始终作为新线嵌入。 (Like a paragraph <p> tag) So you need to tell the h3 tag to display either inline or inline-block . (就像段落<p>标签一样)所以你需要告诉h3标签显示inlineinline-block

Here is my revised weave: http://kodeweave.sourceforge.net/editor/#7b9839fb7971df2a27b7af895169ad8a 这是我的修改编织: http//kodeweave.sourceforge.net/editor/#7b9839fb7971df2a27b7af895169ad8a

 html, body { height: 100%; } .table { display: table; width: 100%; height: 100%; } .cell { display: table-cell; vertical-align: middle; } h3 { display: inline-block; } .btn { margin-top: 15px; } 
 <script src="http://code.jquery.com/jquery.min.js"></script> <script src="http://getbootstrap.com/dist/js/bootstrap.js"></script> <link rel="stylesheet" href="http://getbootstrap.com/dist/css/bootstrap.css"/> <div class="container table"> <div class="page-header cell"> <h3>HEADING</h3> <button class="btn btn-danger pull-right">Button</button> </div> </div> 

You can verify the elements are vertically aligned by setting bootstraps default margins and paddings to 0px if needed. 如果需要,可以通过将bootstraps默认边距和填充设置为0px来验证元素是否垂直对齐。

    .container {
      white-space: nowrap;
      background: #eee;
    }

    .contener:before {
      content: '';
      display: inline-block;
      height: 100%;
      vertical-align: middle;
      margin-right: -0.25em;
    }

    .page-header {
      display: inline-block;
      vertical-align: middle;
      width: 300px;
    }
