html - 如何在两行多个 div 之间添加间距

Question

我想弄清楚如何在上排 4 个 div 和下排 4 个 div 之间添加一个空格。

HTML:

<div class="container">
        <!-- freshdesignweb top bar -->
        <div class="freshdesignweb-top">
            <a href="#" target="_blank">Home</a>
            <span class="right">
                <a href="#">
                    <strong>Back to the freshdesignweb Article</strong>
                </a>
            </span>
            <div class="clr"></div>
        </div><!--/ freshdesignweb top bar -->
        <header>
            <h1><span>Tutorials</span>Demo CSS Table Price Hosting Plan</h1>
        </header>

Answer 1

您正在 #fdw-pricing-table .plan 选择器中使用 margin: 0 5px;。
相反，您可以添加底部或顶部边距以留出一些空间。像这样 -

#fdw-pricing-table .plan {
    margin: 10px 5px;
}
