 * 修复 QA 页「滑动有问题」
 *
 * 页面自带的样式把这一块锁死了：

 *   #text_html_new_1778123265164{ height:597px; position:absolute; top:1px; left:8.3% }
 * 加上 comm.css 里 .view_contents 是 height:100% + overflow:hidden，
 * 于是：内容高出约 600px 的部分被裁掉；而绝对定位元素又不撑开父容器，
 *       父容器永远只有 600px —— 结果就是看不全、也滚不到。
 *
 * 修法：把这一层改回正常文档流（relative + 自适应高度），让内容自然撑开，
 *       页面滚动由站点原有的 nicescroll 负责。

 * 修复「导航栏白字看不见」
 *
 * 站点的导航条本身【没有背景色】，是透明 + 白字 + 白 logo
 * （#comm_layout_header 只有 height:90px，菜单色写死 #ffffff），
 * 它靠【下面那一块深色大图】垫着才看得见：
 *     新闻页  #layout_1764909741362 { height:560px; background:#273272 }
 * 而 FAQ 页是早期导出的老页面，底下没有这块深色区域，
 * 于是白 logo / 白菜单落在白底上就"消失"了。
 *
 * 修法：把导航改成相对定位并用负 margin 把下面的蓝色头图提上来，
 *       让头图从页面最顶端开始铺，导航叠在它上面 —— 与站内其它页面观感一致。
