Css 标题标签背景色延伸到iPad上的列中

我在一个网站上工作，在IPAD（可能还有iPhone）上的CSS方面有问题

基本上在赞助商页面上：。我在不同的部分后面得到了一个红色的背景。我认为这与红色背景的H3标签有关

这里也发生了同样的事情：。他们都在使用Wordpress中的Easy Columns插件

下面是一些示例HTML

有人知道为什么这些部分显示为红色吗？就我的生活而言，我似乎无法理解。看来你的彩车还没有清理干净。可以将其添加到当前样式中：

.singlepost .content-entry h3 { 
  clear: both;
}

.singlepost .content-entry h3 { 
  clear: both;
}
