我无法弄清楚为什么我的明确解决方案无效。我已经使用一类主导航向右浮动导航ul并且标题有点崩溃。
我的clearfix正好位于CSS中的页脚样式之上。
.clearfix::after {
content="";
display: table;
clear: both;
}
答案 0 :(得分:2)
您的代码只是将content=""
更改为content:""
.clearfix::after {
content:"";
display: table;
clear: both;
}
摘录:
body {
max-width: 100%;
padding: 0;
margin: auto;
}
.main-layout {
min-height: calc(100vh - 20px);
}
header {

max-width: 100%;
padding: 1px;
margin: auto;

.main-title {
padding: 3% 5% 0;
