当我将计算机屏幕的大小调整到 980 像素以下时，我的固定导航栏可以正常工作。一旦我的屏幕为 979px 或更小，导航栏崩溃就会启动并完美运行。
然而，当我将代码推送到 Heroku 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——浮标正好落在徽标下方，导致它看起来很奇怪。
这是我的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;
}
}

text-align: center;

}

.navbar-inner {

}
.navbar .nav {

}
#smedia {
padding: 10px 9px 10px 0px;

}
.navbar .divider-vertical {
margin: 10px 9px;
border-left: 1px solid rgb(218,218,218);
}
这是我的标题 HTML：
