HomeWeb Front-endHTML Tutorial板邓:css ol 列表序列号样式_html/css_WEB-ITnose

一。示例

1.自定义序号,

一般的列表顺序都是以1.2.3.为序号,但需要“、”代替“.”  ,这时我们就要自己定义,主要使用了CSS的counter-increment对部分和子部分进行编号,但问题是折行的部分不能自动缩进

 

[css]  view plain  copy

 

1 ol{list-style-type:none;counter-reset:sectioncounter;width:200px;}  2 ol li:before {  3     content:counter(sectioncounter) "、";   4     counter-increment:sectioncounter;  5  }  

执行后为:



2. 标准格式

[css]  view plain  copy

ol{list-style-type:demical;width:200px;}  ol li{ list-style-position:outside;}  

  


 

执行后为:



二、css的UL、ol、li样式

1.list-style-type 属性设置列表项标记的类型。

 

取值:disc 点| circle圆圈 | square正方形 | decimal数字 | decimal-leading-zero 十进制数| lower-roman 小写罗马文字| upper-roman 大写罗马文字| lower-greek小写希腊字母 | lower-latin小写拉丁文 | upper-latin 大写拉丁文| armenian亚美尼亚数字 | georgian乔治亚数字 | lower-alpha小写拉丁文 | upper-alpha大写拉丁文 | none无 | inherit继承
初始值: disc

2.list-style-image 属性使用图像来替换列表项的标记

取值:  list-style-image:none/url

3.list-style-position 属性设置在何处放置列表项标记。

该属性用于声明列表标志相对于列表项内容的位置。外部 (outside) 标志会放在离列表项边框边界一定距离处,不过这距离在 CSS 中未定义。内部 (inside) 标志处理为好像它们是插入在列表项内容最前面的行内元素一样。

取值: list-style-position:inside/outside

 

注:有的时候outside不起作用,原因是加了浮动,

 

4.list-style属性

 

list-style 简写属性在一个声明中设置所有的列表属性。

取值:li-style:list-style-type/list-style-image/list-style-position

 

注:有的时候列序号不起作用,原因是加了浮动,

解决办法是 list-style-position:outside;改成list-style-position: inside;或去掉浮动设置
