行高不适用于ios chrome

一切工作与Chrome桌面，Safari移动伟大。但Chrome不会垂直对齐header中的元素。

的Safari（元素对齐）

与谷歌浏览（元素不对齐）

可以删除float:left在span和使用display:inline-block，因为现在你可以使用vertical-align:middle，那么你还可以设置vertical-align:middle的img因为默认情况下是baseline。

.button { 
 
    font: normal 12px Verdana, Helvetica, Arial, sans-serif; 
 
    margin: 0px; 
 
    display: inline-block; 
 
    background-color: #f5f5f5; 
 
    background-image: linear-gradient(top, #f5f5f5, #f1f1f1); 
 
    color: #444; 
 
    border: 1px solid #dcdcdc; 
 
    -webkit-border-radius: 2px; 
 
    -moz-border-radius: 2px; 
 
    border-radius: 2px; 
 
    cursor: pointer; 
 
    font-weight: bold; 
 
    text-align: center; 
 
    height: 33px; 
 
    line-height: 33px; 
 
    min-width: 25px; 
 
    padding: 0 8px; 
 
    text-decoration: none; 
 
    vertical-align: middle 
 
} 
 
.header { 
 
    max-width: 100%; 
 
    height: 50px; 
 
    line-height: 50px !important; 
 
    background-color: #fff; 
 
    box-shadow: 0 1px 4px rgba(0, 0, 0, 0.15); 
 
    border-bottom: 1px solid #cbcbcb; 
 
} 
 
.header-content { 
 
    max-width: 480px; 
 
    margin: 0 auto; 
 
    padding: 0px 10px; 
 
    font-size: 0 /* inline-block fix gap*/ 
 
} 
 
.header-content span { 
 
    display: inline-block; 
 
    width: calc(100%/3); /* 33.3% */ 
 
    font: normal 12px Verdana, Helvetica, Arial, sans-serif; 
 
} 
 
.header-content .left { 
 
    text-align: left; 
 
} 
 
.header-content .center { 
 
    text-align: center; 
 
} 
 
.header-content .right { 
 
    text-align: right; 
 
} 
 
.header-content img { 
 
    width: 140px; 
 
    vertical-align: middle; 
 
}

<header class="header"> 
 
    <div class="header-content"> 
 
    <span class="left"> 
 
     <a class="button red">Menu</a>
