我有2个部分：prodotto_section（顶部）和catalogo（底部）。问题是，catalogo部分的某些元素与顶部重叠。使用谷歌浏览器检查元素我看到catalogo部分像容器一样高，而prodotto_section高0.我怎么解决它？

css太长了，无法粘贴到此处，我附加了一个jsfiddle链接https://jsfiddle.net/omtwL3k7/
如果您尝试扩展html页面，则h1和选择标记将位于橙色按钮
下答案 0 :(得分：1)
我认为这就是你需要的东西？
https://jsfiddle.net/omtwL3k7/2/
如果不是，请在评论中注明。
我添加了以下CSS：
header, #catalogo {
clear:both;
}
这会使您的“Catalogo”标题和select占据一整行，因此它们必须位于第一部分之下。
