html - 使用CSS使页脚正确 float

我希望两个标题（导航和下载链接）并排浮动
侧。此外，导航项（首页，解决方案，关于，
 联系人），链接的图片就直接在其标题下方浮动
（导航和下载链接）。我在这方面还很陌生，因此非常感谢您的协助！

最佳答案

在#footerContainer上使用CSS Flexbox使其并排放置，并删除float属性。还要分配列flex: 1;，例如：

#footerContainer {
  display: flex;
}

#col1 {
  flex: 1;
  padding: 0 15px;
  position:relative;
  text-align: left;
  text-decoration: none;
}

#col2 {
  flex: 1;
  padding: 0 15px;
  position:relative;
  background-color: #dddddd; /* column 2 background color */
  text-decoration: none;
}


看看下面的代码片段：
