我仍然不太擅长 CSS 或 Javascript(并且由于几个月没有编码工作而生疏了)但这是我的问题:我正在研究我希望将是一个非常简单的响应式模型网站。当浏览器窗口足够大时,所有主菜单按钮都可见/排列在页面顶部,但如果窗口缩小到小于 640px,菜单按钮就会消失(被“display:none”隐藏; ) 并出现一个标记为“MENU”的按钮,用于切换这些隐藏按钮的显示。

我如何做一个 Javascript 来设置显示:内联 block 为类“MVisitorButton”中的按钮(变为显示:无;当浏览器 <640px 宽)点击菜单按钮(当再次点击)即。在显示和隐藏这些按钮之间切换?

最佳答案

I have created a sample of Responsive Navbar using Codepen. 

Sample Navbar

在示例中,我创建了一个导航栏,一旦浏览器宽度低于最小宽度,它就会变成一个下拉菜单。

希望对您有所帮助。 :)
