【问题标题】：Remove Space Between div tags删除 div 标签之间的空格

【问题描述】：

我现在在这里阅读了无数主题，但到目前为止我一直没有运气。我正在尝试删除此页面上 div 之间的空间。

名为“postarea”和“rightsidebar”的 div 与“postadvert”之间的距离应与“postadvert”在其顶部与菜单之间的距离相同。有人可以帮忙吗？

        <p class="postcontent"><h2><a class="postlink" href="#">Fullmetal Alchemist Brotherhood</a></h2><br />In this world there exist alchemists, people who study and perform the art of alchemical transmutation—to manipulate objects and transform one object into another. They are bounded by the basic law of alchemy: in order to gain something you have to sacrifice something of the same value. The main character is the famous alchemist Edward Elric—also known as the Fullmetal Alchemist—who almost lost his little brother, Alphonse, in an alchemical accident. Edward managed to attach his brother's soul to a large suit of armor. While he did manage to save his brother's life, he paid the terrible price of his limbs. To get back what they've lost, the brothers embark on a journey to find the Philosopher's Stone that is said to amplify the powers of an alchemist enormously. Fullmetal Alchemist: Brotherhood is a re-telling of the story from the manga point of view.</p>

【问题讨论】：

标签： css html xhtml-1.0-strict

【解决方案1】：

除了 postarea 和 rightsidebar 之外，还可以浮动其他元素。

类似这样的：http://jsfiddle.net/ePySF/5/

.header #postadvert #contentwrapper {
    float: left;
}

【讨论】：

不幸的是，页面现在看起来有问题。我想像这个页面一样将所有区域分开jsfiddle.net/steveyk/LYLt4
我发现了问题。缩小范围后，这一切都归结为由花车创造的不需要的空间。就在那时我来到了这个页面css-discuss.incutio.com/wiki/Clearing_Space，特别是这个声明“还要记住浮动总是包含子浮动，所以通常最简单的解决方案就是浮动容器！”我将 contentWrapper 浮动到左侧，空间从 postadvert 下方移动到它上方，然后我将标题浮动到左侧，BAM 一切都以我想要的方式显示。此问题现已修复。
