无法获得适合网格宽度的列

Question

我使用的是语义用户界面，无法正确设置网格。根据文档，Semantic UI使用16列，我试图在左侧放置宽度为three的列，并在其旁边放置宽度为thirteen的列。这是它的外观（图片被裁剪）：

我已经使用Bootstrap很长时间了，现在尝试使用Semantic UI。我错过了什么？ Demo

<header>
    <div class="mobile hidden">
        <div class="ui container">
            <div class="ui grid">
                <div class="eight column">
                    <div class="ui secondary menu">
                        <a class="active item">
                            Home
                        </a>
                        <a class="item">
                            Messages
                        </a>
                        <a class="item">

            <section class="thirteen column olive">
                Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ab doloremque illum quas? Dolore dolorem dolorum ipsum? Commodi error excepturi laboriosam magnam nobis odio suscipit unde! Alias atque dicta reiciendis sapiente!

    </div>
</div>

Answer 1

您在wide元素中缺少另外两个类field和HTML。改变如下

<aside class="three wide field column red"></aside>
<section class="thirteen wide field column olive">
    Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ab doloremque illum quas? Dolore dolorem dolorum ipsum? Commodi error excepturi laboriosam magnam nobis odio suscipit unde! Alias atque dicta reiciendis sapiente!
</section>
