2列多行使用CSS

问题描述

| 我对编码和CSS领域都不陌生，我试图创建一个具有2列和类似于表的多行的页面，但是不确定这是否是实现结果的正确方法。笔记在将其复制到外部样式表之前，我正在使用内部样式表。我已经简单地将列命名为leftnav和leftnav1以及content和content1。我知道这些名称并不理想，但是我正在尝试确定对页面进行编码的最佳方式，而不是担心当前的命名约定。码

解决方法

为了将页面分为几列，最好花费一些时间来学习网格CSS框架，例如960，Blueprint或OOCSS。将页面（或页面的一部分，如果需要）划分为所需的列数后，可以将每列划分为固定高度或可变高度的行。虽然您自己想解决这个问题是很崇高的，但是我建议您，因为您“是编码世界的新手”，因此，您可以通过查看现有的示例和解决此已知设计问题的方法，从中受益匪浅并从一开始就采用最佳实践方法。编辑好的，既然我们坚持使用现有功能，那么让我们来看看一种清理样式的方法。您在两个地方声明了完全相同的样式：Leftnav和Leftnav1最好更改为：

.leftnav { float: left; margin-top: 10px; width: 200px; }

然后，您可以将该类应用于两个左侧的导航容器。 content和content1样式也是如此。要回答您的原始问题，“这是正确的方法吗？”，我会说，“严格来说，不是。但这是一种方法。更好的方法可能是使用以下方法：

<body>
    <div id=\"backdrop\"></div>
    <div id=\"wrapper\">
        <div id=\"logo\">logo</div>

        <div id=\"topnav\">
            <ul>
                <li>about</li>
                <li>browse</li>
                <li>faq</li>
                <li>contact</li>
            </ul>
        </div>

        <div id=\"innerwrapper\">
            <div id=\"header\">

                <div id=\"innerhead\">
                    Sample text
                </div>

            </div>

            <div class=\"leftCol col300\">About</div>

            <div class=\"main\">

                Lorem ipsum dolor sit amet,at elementum neque vestibulum sollicitudin semper neque,vitae metus. Nibh ligula mi. Faucibus rutrum elit turpis,nec congue quam ipsum felis neque et,wisi amet,architecto eros congue. Maecenas suspendisse tellus arcu eget pharetra,rhoncus aenean sapien morbi nec arcu,vivamus aliquet lorem amet at,vestibulum purus sociis varius id. Imperdiet id magnis turpis beatae aliquet,vestibulum dolor nec eget eu cras lobortis,vel rerum,risus sed et,libero et non eros commodo. Taciti eu leo sollicitudin malesuada,nibh duis amet aenean,odio aptent ultrices. Tristique morbi nunc ullamcorper ut curabitur. Et a in ut sem varius,sem rutrum vehicula sem sed,at diam amet erat vel. Et sit in ante felis vitae sit.

                Quam eget sed elit natoque velit,enim mauris mauris urna,integer amet tellus illo ipsum,dolor fermentum cursus enim mollis tristique porttitor. Non dignissim. Sit ligula leo tincidunt,justo ut ut placerat quisque non,risus nonummy. Ultrices mauris congue aliquam aliquam felis,at placerat,amet vestibulum dictumst pellentesque iaculis risus. Sem sed impedit nullam ultrices lorem aliquam,nulla tellus consequatur in ornare magna. Viverra amet pede in in ornare eu,id arcu. Justo mus suspendisse praesent et,amet mattis convallis ullamcorper felis,fermentum nibh at ac,ullamcorper ipsum auctor et maecenas,aliquam molestiae in qui. Massa elit suspendisse penatibus molestie libero dolor,non leo vitae,sollicitudin a,platea tristique iaculis,tortor augue non est. Ante rutrum quis pellentesque lacinia convallis non,vestibulum nibh nunc luctus nibh a,in amet,iaculis dui ornare pede laoreet eu. Cursus integer vehicula quis,justo eget purus mattis donec vestibulum nunc,nunc vel eros lectus.

            </div>

            <div class=\"leftCol col300\">About</div>

            <div class=\"main\">

                Lorem ipsum dolor sit amet,nunc vel eros lectus.

            </div>
        </div>
    <div>
</body>

然后，您需要的三种样式变为：

.leftCol { float: left; }
.col300 { width: 300px; }
.main { overflow: hidden; }
