åæï¼/post/如何把标题上面的网站隐藏
要将网站标题上面的新浪博客隐藏,需针对首页不同元素进行代码修改。源码
首先,源码隐藏最底部文字,源码代码为:.foot{ display:none;}
接着,源码qtp 源码去掉最上面新浪3.0代码,源码动漫社区源码php代码为:.bodyTop{ display:none;}
去掉横幅代码,源码代码为:.banner{ display:none;}
去除顶部白条,源码代码为:.bodyTop{ background:#transparent}
隐藏特定元素,源码代码包括:.nka{ display:none;}.nktd{ display:none;},源码去除顶部菜单部分(登录、源码注册、源码搜索、源码pvc指标公式源码帮助,源码无HOME),源码代码为:.menu .text a{ display:none;}.menu .home a{ display:none;},去除顶部菜单部分(HOME┆登录┆注册┆搜索┆帮助),破译版游戏源码代码为:.menu a{ display:none;}.menu .text{ display:none;},去掉正文阅读处(固定链接┆评论┆引用┆阅读),代码为:.feeds .function a{ display:none;}.feeds .function td{ display:none;},去掉正文底部翻页处文字(第(1/)页 1 2 3 4 5 6 >>),qfile 5.15 源码下载代码为:.gea{ display:none;},隐藏题图处的博客名字,代码为:.banner .title td{ display:none;},去掉新浪计数器的代码,代码为:#labelFM{ display:none;}
实现这些操作的具体步骤如下:点击控制面板中的个人首页维护,选择自定义空白面板,若已有模块则打开该模块显示源代码,粘贴隐藏代码并保存。若新增面板,先敲空格键,显示源代码区域粘贴代码,确保隐藏效果,保存面板后在个人首页定制界面选取并保存。
