当我将电脑屏幕大小调整到980 px以下时，我的固定导航栏工作正常。一旦我的屏幕为979 px或更少，导航栏崩溃就会启动并完美工作。
然而，当我把代码推到Heroku上并在我的iPhone 4S上加载该网站时，我的导航栏不仅没有崩溃，而且看起来有点不同--浮动右边落在徽标下面，导致它看起来很奇怪。
下面是我的custom.css.scss文件：

@import "bootstrap";
@import "bootstrap-responsive";

/* universal */

html {
overflow-y: scroll;
}

body {
padding-top: 61px;
}

@media (max-width: 979px) and (min-width: 768px) {
body {
    padding-top: 0;
}
}

@media (max-width: 768px) {
body {
    padding-top: 0;
}
}

section {
    overflow: auto;
}

textarea {
resize: vertical;
}

.center {
text-align: center;
}

.center h1 {
margin-bottom: 10px;
}

.container {
margin-top: 0px;
margin-right: auto;
margin-bottom: 0px;
margin-left: auto;
max-width: 1000px;
}

.span4 {
width: 323px;
margin-left: 20px;
text-align: center;
}

@media (max-width: 767px) {
#footer {
    margin-left: -20px;
    margin-right: -20px;
    padding-left: -20px;
    padding-right: -20px;
}
}

}

.navbar .divider-vertical {

}
