解决Footer与Main内容重叠问题

问题描述

我正在学习HTML和CSS，制作迷你作品集项目时遇到Footer重叠Main内容的问题。尝试调整main的内边距、宽度无效；给body添加height、display:flex和flex-direction属性后问题仍未解决。页面在75%缩放时显示正常，100%缩放时出现重叠。

解决方案

问题根源

body 设置固定 height:100vh，限制了页面总高度，当main内容实际高度超过视口高度时，footer会被挤压重叠；
.main 同时设置 flex:1 和 min-height:100vh，加上内外边距后，main实际高度会超出body的限制；
.main__texto 固定了 height:482px，在内容溢出或屏幕尺寸变化时，会破坏布局结构。

修改步骤

将 body 的 height:100vh 改为 min-height:100vh，让页面能根据内容自动扩展高度；
移除 .main 中的 min-height:100vh，依赖 flex:1 让它占据body的可用空间；
删除 .main__texto 中的 height:482px，让内容自然撑开容器。

修改后的CSS代码

* {
    margin: 0;
    padding: 0;
}

body {
    box-sizing: border-box;
    background-color: #000;
    color: #F6F6F6;
    min-height: 100vh; /* 修改为min-height */
    display: flex;
    flex-direction: column;
}

    padding: 5% 15%;
    display: flex;
    align-items: center;
    justify-content: space-between;
    gap: 40px;
    /* 移除min-height:100vh */
}
