bootstrap導航欄崩潰在iphone上的計算機上工作

Question

當我將我的電腦屏幕調整到980像素以下時，我的固定導航欄正常工作。一旦我的屏幕小於或等於979像素，導航欄崩潰就會啓動並完美運行。

但是，當我將代碼推到Heroku上並在我的iPhone 4S上加載該網站時，我的導航欄不僅沒有崩潰，而且看起來有點不同 - 浮標右下方掉落在徽標下面，使其看起來很奇怪。

這裏是我的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; 
} 
} 

/* typography */ 

h1, h2, h3, h4, h5, h6 { 
line-height: 1; 
} 

h1 { 
font-size: 3em; 
letter-spacing: -2px; 
margin-bottom: 30px; 
text-align: center; 
} 

h2 { 
font-size: 1.7em; 
letter-spacing: -1px; 
margin-bottom: 30px; 
text-align: center; 
font-weight: normal; 
color: $grayLight; 
} 

p { 
font-size: 1.1em; 
line-height: 1.7em; 
} 

/* header */ 

#logo { 
float: left; 
font-size: 1.7em; 
color: #555555; 
text-transform: uppercase; 
letter-spacing: -1px; 
padding-top: 5px; 
font-weight: bold; 
line-height: 2; 
} 

#logo:hover { 
text-decoration: none; 
} 

.navbar-inner { 
min-height: 60px; 
} 

.navbar .nav { 
margin: 0 -13px 0 0; 
} 

.navbar-fixed-top .navbar-inner { 
box-shadow: none; 
border-bottom: 1px solid #d4d4d4; 
} 

.navbar .btn-navbar { 
margin-top: 16px; 
} 

li { 
line-height: 40px; 
list-style: none; 
} 

#smedia { 
padding: 10px 9px 10px 0px; 
font-size: 16px; 
text-shadow: none; 
} 

.navbar .divider-vertical { 
margin: 10px 9px; 
border-left: 1px solid rgb(218,218,218); 
}

兩件事情我會提到。確保您擁有correcdt視在HTML文檔

<meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" /> 

的頭部設置其次我注意到，您的媒體查詢是有點散。最好將這些內容放在一起並放在文檔的結尾處。如果它們不在CSS的末尾，那麼儘管有媒體查詢，其他CSS將覆蓋它。
