css 类无法正常工作

debugcn 发表于 Dev

我正在重新设计我的网站。这样做我发现自己在使用我编写的 css 代码时遇到了一些问题。

我使用 div 来获取图像和一些彼此相邻的文本。我无法将文本移动到正确的位置（见图片）当它在 css 文件中时，左边距似乎不起作用，但是当它直接嵌入到 div 标签中时它起作用，我做错了什么?

我还想补充一点，我不需要在 html 代码中设置图像大小，但它在 css 代码中这可能吗？

我得到了什么

我想要的是

body

	background:#333 url(bg.jpg) repeat top left;
	font-family:Arial;
	color:white;
	text-align:center;

您只需要更改一些样式，并将其替换<article>为<div>（对于 IE 支持）

div.wrapper {
  width: 800px;
  overflow: hidden;
}
div.toolsWrapper {
  width: 980px;
  overflow: hidden;
}
div.left {
  width: 200px;
  float: left;
  margin-right: 40px;
  padding-left: 40px;
}
div.right {
  color: white;
  display: inline-block;
  position: absolute;
  top: 0;
}
.wrapper {
  position: relative;
  width: 50%;
}
.title {
  color: #4B9F49;
}
.inner_title {
  color: white;
}
.blockquote {
  border-left: 3px solid #0CD673;
  padding-left: 5px;
}
#article {
  background: black;
}

<div id="article">
  <h3>
    <a href="Damp" class="title">Audio Projects</a>
  </h3>
  <blockquote class="blockquote">
    <h3>
      <a href="Damp" class="inner_title">Class D Amplifier</a>
    </h3>
    <div class="wrapper">
      <img src="Damp/Damp_front.JPG" style="height:80px; width:200px;"/>
      <div class="right">
        Some text that is now next to the image. 
      </div>
    </div>
  </blockquote>
</div>
