我正在开发我的第一个网站，当我减小浏览器的宽度时，我的内容和页脚之间会出现一个空白。在全尺寸一切都很好。有没有办法让它不出现缝隙？
如果那里的代码比要求的多，我们深表歉意，因为这是我第一次为网站编写代码，而且我已经自学了。
非常感谢任何帮助
** 编辑** 我已经弄清楚了问题的原因。页脚上方 div 中的图像正在缩小以保持其比例，从而在 div 中创建空白区域。我能够通过从 html 文件中的 div 中删除图像来解决该问题。我将图像添加到 div 作为 CSS 中的背景，并使用以下样式来解决问题
.locally-img {
width: 60vw;
height: 60vh;
background: url(./images/rsz_1locally.png);
background-size: 100% 100%;
}
【问题讨论】：
要准确理解您的意思有点困难，但您的代码通常存在两个问题：
max-height、height、padding-top 的位置过多。将其与溢出相结合也应受到限制。.item2、.item2 等选择器，而是像.item 这样的通用选择器。 .item2 p 也是如此。如果.item2 中的p 需要特殊，那很好，但如果所有p 元素都应该以相同的方式设置样式，只需创建一个选择器链接p {...}。p) 上的 padding 或 margin 设置为百分比很难控制。请改用em。我在这里做了一些修改，但可能也破坏了一两件事。
