标志(浮动:左)& list(float:right)不可见

标签: html css html5 css3 webpage

在HTML5& CSS3,徽标需要浮动到左上角和项目/菜单列表需要浮动到右上角。

在此处的输出中,徽标由于某种原因不可见。但是" alt"被提及,"代替徽标。"

这是从我这边收到的输出。我在网页顶部用白色标记了它: Here is the output is received from my side. I've marked it with white color on top of the webpage

我无法找到徽标可见的原因。

您的元素正确浮动,但是,父级的最大宽度为110px,由类row提供,因此,基本上,它们没有太多空间来定位
