Question

我一直很难在父元素中垂直对齐div。我尝试了vertical-align: center;，display: inline-block;以及我在垂直对齐方面可以找到的任何其他内容，但实际上并没有对我有用。如果这会影响任何事情，我正在使用bootstrap。

我想在div #banner中垂直对齐div .bannerContent。我希望这是一个简单的修复，我只是遗漏了一些简单的东西。

当我尝试使用display: table-cell;时，它已经破坏了水平居中。

我已经包含了整个文件，以防万一从其他地方破坏它。万分感谢！

这是我的HTML：

<!doctype html>
<html>
<head>
    <title>My title here</title>
    <link rel="stylesheet" href="css/bootstrap.min.css">
    <link rel="stylesheet" href="css/main.css">
    <link href="https://fonts.googleapis.com/css?family=Oswald" rel="stylesheet">
</head>
<body>
    <div id="banner">
        <div class="bannerAlign">
            <nav class="navbar navbar-default navbar-static-top">
                <ul class="nav navbar-nav right">
                    <li><a href="#">Contact</a></li>
                    <li><a href="#">Help</a></li>
                    <li><a href="#">Another Link</a></li>
                  </ul>
            </nav>
        </div>
        <div class="container bannerContent"> <!-- I want this div vertically aligned -->
            <img id="profile" src="images/profile.jpg" />
            <header>
                <h1>My name here</h1>
                <h4>More words here</h4>
            </header>
        </div>
        <span class="glyphicon glyphicon-menu-down down-arrow"></span>
    </div>
    <div class="container">
        <div class="content">
            <div class="well">
                <h1>Some content here</h1>
            </div>

只需使用以下css：

#banner {
    display: flex;
    align-items: center;
}

您可以使用此：css-tricks。最简单的方法是使用flexbox作为超级用户写的。
