中心以前使用媒体查询浮动内容

时间：2016-12-15 18:27:06

标签： html css media-queries centering

我正在尝试将问候div直接置于移动屏幕徽标的正下方。无论我做什么，它似乎都不起作用。问候只是一直坚持到右边。我尝试添加和更改显示值，边距，填充，有和没有bootstrap列。什么都行不通:(请帮帮忙？

2 个答案:

答案 0 :(得分：0)

#greet的float属性不是h1 / h2。您在@media代码中引用了h1 / h2而没有更改#greet本身的浮点值。删除＆＃39;＆gt; H1＆＃39;和＆＃39;＆gt; H2＆＃39;来自@media部分，这将为您提供您想要的。

答案 1 :(得分：0)

清除float和padding并且有效：

#greet {float: none; padding-left: 0; }
