HomeWeb Front-endHTML Tutorial常用css样式问题_html/css_WEB-ITnose

1.数据测试
  做项目中,通常会遇到需要添加大量数据作测试的情况,而大量的数据,重复一条一条的添加,势必浪费大量宝贵的时间。
  解决办法:
    a.数据采集;
    b.从数据库中导出相似的记录,复制n遍之后,稍作修改,在数据库中直接运行sql的insert语句;
   

2.关于页面标准化的问题
  目前发现前端的页面除了有部分变形之外,还存在如下问题:
    a.当数据行数不够时,div高度自动缩减:添加min-height属性;
    b.当数据行数过多时,div高度制动增加:设定height和overflow属性;

    说明:max-height和height共同使用的时候,max-height将无效;(min-height类似)
             max-height仅在没有height属性的时候生效;(min-height类似)
             max-height的高度会随着内容的增加而自动增加;


    c.当数据字符超出div或者li的宽度时,数据自动换行到下一行导致重叠:使用line-height和overflow:hidden共同控制;
