我正在尝试使用Google MDL文档中的fixed tab example。这是我的代码:
CODE
<!-- Simple header with fixed tabs. -->
<div class="mdl-layout mdl-js-layout mdl-layout--fixed-header mdl-layout--fixed-tabs">
<header class="mdl-layout__header">
<div class="mdl-layout__header-row">
<!-- Title -->
<span class="mdl-layout-title">Title</span>
</div>
<!-- Tabs -->
<div class="mdl-layout__tab-bar mdl-js-ripple-effect">
<a href="#fixed-tab-1" class="mdl-layout__tab is-active">Tab 1</a>
<a href="#fixed-tab-2" class="mdl-layout__tab">Tab 2</a>
<a href="#fixed-tab-3" class="mdl-layout__tab">Tab 3</a>
</div>
</header>
<div class="mdl-layout__drawer">
<span class="mdl-layout__title">Title</span>
</div>
<main class="mdl-layout__content">
<section class="mdl-layout__tab-panel is-active" id="fixed-tab-1">
<div class="page-content"><!-- Your content goes here --></div>
</section>
<section class="mdl-layout__tab-panel" id="fixed-tab-2">
<div class="page-content"><!-- Your content goes here --></div>
</section>
<section class="mdl-layout__tab-panel" id="fixed-tab-3">
<div class="page-content"><!-- Your content goes here --></div>
</section>
</main>
</div>
输出
问题是我的抽屉图标位置错误!它与顶部而不是中心对齐。这有什么不对?
