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，但我运行遇到了问题。问题是当网页在移动设备上时，例如导航栏折叠，因此它适合设备，但是当他们单击 Navbar-Toggle 按钮时，链接出现在 header 的顶部，我和我不希望这发生。我想要发生的是，当他们单击它时，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 header-image向下移动。

Standard CSS Custom CSS

Answer 1

替换此 CSS

nav.mobile_menu {
background-color: #fff;
display: none;
float: left;
left: -15px;
overflow: hidden;
padding: 0 15px;
position: absolute;
text-align: left;
top: 100px;
width: 100%;

}

Answer 2

这些规则导致了它：参见工作示例。

删除高度：50 和上边距：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);
