html - 滑入式菜单 : witdth and position:fixed

Question

我已经尝试了几个小时来创建滑入式菜单，但仍然有问题。

我的菜单应该满足以下几点:

• 只有 html 和 css(没有 js)
• 更改点击图标
• 如果宽度 > x(而不是没有汉堡包图标)，则完整菜单可见
• 粘性标题
• 响应迅速(适合移动设备)
• 应该在现代浏览器中工作；)

这就是我到目前为止所做的:

/* Micro reset */
*,*:before,*:after{-webkit-box-sizing:border-box;-moz-box-sizing:border-box;box-sizing:border-box;margin:0;padding:0;}
html, body { height: 100%; width: 100%; font-family: Helvetica, Arial, sans-serif; }

body {
  /* Without this, the body has excess horizontal scroll when the menu is open */
  overflow-x: hidden;
}

h1, h2, p {
  margin-bottom: 3em;
  line-height: 2em;
}

h1 {
  padding-top: 5em;
}
/* hb icon */

在 codepen 上观看:http://codepen.io/anon/pen/JGwjXZ

现在的问题是，如果宽度 > 1600，标题(红色)将不会停在右侧。 (也许还有其他问题……)

有什么技巧可以让页眉的最大宽度也一样吗？如果我删除“位置:固定；”在类里面它有效。但是标题应该在滚动时可见。

感谢您阅读我的问题! 八字

我做了以下事情:

.rofl {
  max-width: 1600px;
}

将最大宽度添加到您的 css 将阻止它超过所选宽度。
