我是网站的新用户,我正在创建一个可扩展的网站。将屏幕缩小到650px以下时会出现问题。出于某种原因,我的菜单的背景正在消失。我已经多次查看代码,无法找到我的错误。 请帮忙!
以下是我的信息页的链接:http://mnice.mydevryportfolio.com/portfolio/
以下是我到目前为止所使用的Media CSS代码:
/************************************************************************************

#pagewrap {

}

#sidebar {

}
#sidebar .widget {

}
/* embedded videos */
.video embed,
.video object,
.video iframe {

}
}

}

}

}

}

}

}
/* sidebar */
#sidebar {
width: 100%;
margin: 0;
float: none;
}
#sidebar .widget {
padding: 3% 4%;
margin: 0 0 10px;
}
/* embedded videos */
.video embed,
.video object,
.video iframe {
min-height: 250px;
}
}
/************************************************************************

@media screen and (max-width: 480px) {

任何帮助将不胜感激!
答案 0 :(得分:3)
media.css第63行将position:static
替换为bottom:auto;
中的#main-nav
#main-nav {
bottom: auto;
}
答案 1 :(得分:1)
您更改了定位上下文
@media screen and (max-width: 650px)
#main-nav {
position: static;
}
如果删除static
bg颜色返回...那么只需调整位置值即可。
答案 2 :(得分:1)
只需将overflow:hidden
添加到#main-nav或将float:left添加到相同的ID,这也可以解决问题。
这个问题的原因是#main-nav的浮动子节点和#main-nav本身不是,在这种情况下容器div崩溃。使用'clearfix'类,或者如我所提到的,添加overflow:hidden
或float:left
将导致容器包含浮动元素。
答案 3 :(得分:0)
问题在于您的媒体查询,它们负责更改不同屏幕尺寸的布局:
继续添加:
@media screen and (max-width: 650px)
#main-nav {
bottom: inherit;
}
