HTML5＆CSS3居中

Question

我正在使用以下HTML & CSS代碼摘錄。 「navmenu」項目在IE中跨越頁面的整個寬度，但在Chrome中保留右側的空間。完整的頁面可以在www.bobabend.com上查看。任何人都可以告訴我要更改什麼，以便在兩個瀏覽器中的「navmenu」項目都是全寬度的？

.navmenu { 
 
    padding: 0; 
 
    display: block; 
 
    z-index: 2; 
 
    clear: none; 
 
    margin-top: -13px; 
 
    margin-left: auto; 
 
    margin-right: auto; 
 
} 
 

 
.navmenu ul { 
 
    padding: 0; 
 
    background-color: #0000FF; 
 
} 
 

 
.navmenu li { 
 
    padding: 0; 
 
    list-style: none; 
 
    position: relative; 
 
    background-color: #006500; 
 
    float: left; 
 
    border: thick ridge #CC9900; 
 
} 
 

 
.navmenu ul li a { 
 
    text-align: center; 
 
    font-family: source-sans-pro, "Trebuchet MS", Verdana, Arial, sans-serif, helvetica; 
 
    text-decoration: none; 
 
    height: 45px; 
 
    width: 200px; 
 
    display: block; 
 
    color: #FFF; 
 
    text-shadow: 1px 1px 1px #000; 
 
    font-size: medium; 
 
    vertical-align: middle; 
 
    line-height: 40px; 
 
} 
 

 
.navmenu ul ul { 
 
    position: absolute; 
 
    visibility: hidden; 
 
    top: 32px; 
 
} 
 

 
.navmenu ul li:hover ul { 
 
    visibility: visible; 
 
} 
 

 
.navmenu li:hover { 
 
    background: #09F; 
 
    z-index: 1; 
 
    font-weight: bolder; 
 
} 
 

 
.navmenu ul li:hover ul li a:hover { 
 
    background: #CCC; 
 
    color: #000; 
 
} 
 

 
.navmenu a:hover { 
 
    color: #000; 
 
    font-weight: bolder; 
 
} 
 

 
.clearfloat { 
 
    clear: both; 
 
    margin: 0; 
 
    padding: 0; 
 
} 
 

 
.wrapper { 
 
    z-index: 1; 
 
    width: 1050px; 
 
    margin-left: auto; 
 
    margin-right: auto; 
 
}

Answer 1

爲什麼不乾脆把

.navmenu { 
    padding: 0; 
    z-index: 2; 
    clear: none; 
    margin-top: -13px; 
    margin-left: 0; 
    margin-right: 0; 
}
