.toptab {
    min-width:60px;/*最小宽度*/
    _width:60px; /*实现min-width兼容 IE6*/
    overflow: hidden;/*不出现滚动条*/
    float:left;/*左浮动*/
    padding:2px 6px 0 6px;/*定义元素内边框，上右下左*/
    margin:0 10px 0 0;/*定义元素外边框，上右下左*/
    text-align:center;/*文本居中对齐*/
    height:22px;
    line-height:22px; /*两个高度一致，使文本上下垂直居中 */
    font-size: 12px;/*文字大小*/
    background-color:#ffffff;/*元素背景颜色*/
    color: #333333;/*文字颜色*/
    font-weight: normal;
    text-decoration: none;/*不出现下划线*/
}

ps：内联(display:inline;)属于行布局，其特性是在一行里进行布局，不能设置宽高

编程学习 DIV, JS 0 Comments

以下是宽度变化的示例，高度也可参考：

<script type="text/javascript">
    function initWidth() {
        var bodyWidth = document.compatMode == "BackCompat"?document.body.clientWidth:document.documentElement.clientWidth;
        document.getElementById("Content").style.width = bodyWidth - 180;
    }
    initWidth();
    if (document.attachEvent) {
        window.attachEvent('onresize', initWidth);
    } else {
        window.addEventListener('resize', initWidth, false);
    }
</script>
