javascript - 单击 Navbar-Toggle 按钮时使页面向下移动

Question

我正在制作一个网站，以便练习我的网络技能，但我遇到了一个问题。问题是当网页在移动设备上时，例如 Navbar 折叠，因此它适合设备，但是当他们单击 Navbar-Toggle 按钮时，链接出现在我拥有的标题顶部，我不希望这样发生。我想要发生的是，当他们点击它时，如果您理解我的意思，它会将所有元素向下移动。

如果你不去这个网站 -> www.thestartupguys.co.uk <- 并缩小页面直到它变成你必须切换导航栏然后切换它的地方，你会看到标题图像向下移动.

这些规则导致了它:参见工作示例。

移除 height: 50 和 margin-top: 20px

.navbar-brand img,
.navbar-nav {
    margin-top: 20px;
    display: inline;
    text-transform: uppercase;
    height: 50px;
}

移除高度:90px

.navbar-default {
    font-family: 'Raleway', sans-serif;
    height: 90px;
    background-color: #fff;
    box-shadow: 0px 2px 20px 0px rgba(0, 0, 0, 0.25);
}

@import url(https://fonts.googleapis.com/css?family=Raleway:100, 200, 300, 400, 500, 600, 700, 800, 900);
@import url(https://fonts.googleapis.com/css?family=Lato);
