我试图将我的旁边元素浮动到我的主元素的右边，并且由于某种原因它太大了。我将主要宽度指定为60％，将旁边指定为39％（因为正文元素为99％），但不知何故，这个比例没有正确显示。
这是html和css：

padding: 0;

<h3>History of the guitar</h3>
<p>In this documentary, Julian Bream walks you through the history of the classical guitar in Spain. He plays pieces that are relevant to the different eras of the guitar. Although the documentary is fairly slow paced - it is worth the watch! <br>

<h2 class="orange_header">Classical Guitar</h2>
<p>The guitar is arguably the most popular and versatile instrument in the world. It is used in a variety of different musical styles like rock, blues, folk and pop. <strong>This school focusses on the classical style of playing. </strong> With classical
guitar you use nylon strings and play all the voices (bass, alto, soprano) using a special right hand technique. The guitar becomes a “mini orchestra”.</p>
<h2 class="orange_header">Before you start...</h2>
<p>This school requires you to know a few basics before you can start the lessons. <br>We assume that you can:</p>
<ul>
<li>Tune your guitar</li>
<li>Play chords comfortably</li>
<li>Read tablature</li>
</ul>
<p>If you can‘t do these things - do not worry!<br> We suggest you make use of the <a href="useful_links.html">“Useful links”</a> page to teach yourself the basics of guitar.</p>

答案 0 :(得分：0)
我认为你误解了宽度的概念。您将width的{{1}}设置为main。这将仅涵盖60%代码的60%。您还将body的{{1}}设置为width，但此元素是aside的父级。这意味着它将覆盖39%容器的main。我不知道我是否理解了你的问题（我现在没有声誉，要求提供更多详细信息）所以我认为你想要的东西如下（请原谅我糟糕的绘图技巧）：< / p>
我建议进行以下更改：
首先创建一个新的39%元素（我将其命名为main）并在其中添加左侧浮动内容。
div然后将您的CSS样式更改为：
main-content
