html - .css 页面切断页脚，不会滚动

Question

每当我向页面添加相当数量的内容时，页面都不会滚动并且页脚会被截断。我尝试了其他问题的解决方案，但到目前为止对我没有任何帮助。有什么建议么？

html {
    overflow: hidden;
    height: 99%;
}

body {
    background: #ffffff;
    height: 99%;
    margin: 0;
    padding: 0;
    line-height: 150%;
    text-align: center;
}

* {
    font-size: 8pt; 
    font-family: Tahoma, Verdana, sans-serif; 
    color: #000000;
    text-align: left;
}

    width: 600px;

看这个:

#mainContentArea {
    margin: 0 auto 0 auto; 
    display: table; 
    height: 100%;         # set the height to the same as the parent element
    position: relative; 
    overflow: hidden;     # hide (prevent scrolling) content that overflows
    width: 600px;
}

删除 overflow 指令，或将其设置为 auto 应该可以解决问题。
