一、建议段落

      p:

I like apples and oranges.                I also like bananas, mangoes, cherries, apricots, plums, peaches and grapes.        You can see other fruits I like here.
                
Warning: Eating too many oranges can give you heart burn.
                
My favorite kind of orange is the mandarin, properly known            as citrus reticulata.        Oranges at my local store cost $1 each $2 for 3.
                    
The FDOC regulates the            Florida citrus industry.
                    
I still remember the best apple I ever tasted.        I bought it at 3 o'clock            on December 7th. 

二、DIV

       没有具体含义如果找不到合适的元素，可以找他建立结构，它的含义是由全局属性提供的

       缺点：只限于设计者的网页或web应用系统，别人并不了解。

 三、预先编排好格式的内容（pre）

        浏览器不会编程pre元素里的内容，比如说浏览器会把几个连续的空格合成一个，但是如果用了pre元           素的话就是保存原来的样式；pre元素经常和code这一类的元素一起使用。

    var fruits = ["apples", "oranges", "mangoes", "cherries"];    for (var i = 0; i < fruits.length; i++) {        document.writeln("I like " + fruits[i]);    }        
                    var fruits = ["apples", "oranges", "mangoes", "cherries"];    for (var i = 0; i < fruits.length; i++) {        document.writeln("I like " + fruits[i]);    }

 四、引有别处的内容（blockquote）：

       表示是引用的别处的内容，局部属性cite表示出自哪里的url

I like apples and oranges.                I also like bananas, mangoes, cherries, apricots, plums, peaches and grapes.        You can see other fruits I like here.

             The apple forms a tree that is small and deciduous, reaching 3 to 12 metres        (9.8 to 39 ft) tall, with a broad, often densely twiggy crown.        The leaves are alternately arranged simple ovals 5 to 12 cm long and 3?        centimetres (1.2?.4 in) broad on a 2 to 5 centimetres (0.79 to 2.0 in) petiole        with anacute tip, serrated margin and a slightly downy underside. Blossoms are        produced in spring simultaneously with the budding of the leaves.        The flowers are white with a pink tinge that gradually fades, five petaled,        and 2.5 to 3.5 centimetres (0.98 to 1.4 in) in diameter.        The fruit matures in autumn, and is typically 5 to 9 centimetres (        2.0 to 3.5 in) in diameter.        The center of the fruit contains five carpels arranged in a five-point star,        each carpel containing one to three seeds, called pips.

五、增加主题分离

      hr:代表向另一相关主题转换

I like apples and oranges.                I also like bananas, mangoes, cherries, apricots, plums, peaches and grapes.        You can see other fruits I like here.

六、将内容组织成列表

      1、有序列表（ol）:项目用li表示--

            局部属性：start、reversed、type(1,A。。。)

I like apples and oranges.                I also like:        
    
            
     
bananas
            
     
mangoes
            
     
cherries
            
     
plums
            
     
peaches
            
     
grapes
        
    

      2、无序列表（ul）:项目用li表示 

        项目号的样式由list-style-type控制

I like apples and oranges.                I also like:        
    
            
     
bananas
            
     
mangoes
            
     
cherries
            
     
plums
            
     
peaches
            
     
grapes
        
    

      3、li:表示列表中的项目

I like apples and oranges.                I also like:        
    
            
     
bananas
            
     
mangoes
            
     
cherries
            
     
plums
            
     
peaches
            
     
grapes
        
    

      4、生成列表说明（dl,dt,dd）

             dl:表示说明列表

             dt:表示说明列表中的术语

             dd:表示说明列表中的定义

I like apples and oranges.                I also like:                
    
            
     
      Apple
     
                
     
      The apple is the pomaceous fruit of the apple tree
     
                
     
      Malus domestica
     
            
     
      Banana
     
                
     
      The banana is the parthenocarpic fruit of the banana tree
     
                
     
      Musa acuminata
     
            
     
      Cherry
     
                
     
      The cherry is the stone fruit of the genus 
      Prunus
     
        
    

      5、生成自定义列表

            列子是一个复杂的列表，不做过多的深入，后续会了解，只要知道ul能够做很复杂的列表

                    
            
            
                                            I like apples and oranges.                I also like:                
    
            
     
bananas
            
     
mangoes, including: 
                
     
                    
      
Haden mangoes
                    
      
Keitt mangoes
                    
      
Kent mangoes
                
     
            
     
cherries
            
     
plums, including:                
      
                    
       
Elephant Heart plums
                    
       
Stanley plums
                    
       
Seneca plums
                
      
            
            
     
peaches
            
     
grapes
        
    
        You can see other fruits I like here.    

   七、使用插图figure:

       一个独立的内容单元，可带标题，通常 作为一个整体被文档的主体引用，删除了也不会影响文档的意       思  

       figcaption表示插图的标题,必须放在最后或者是最前面

        列子生成了将code元素裹在其中的插图

I like apples and oranges.                
    
            
                 
     var fruits = ["apples", "oranges", "mangoes", "cherries"];
                document.writeln("I like " + fruits.length + " fruits");
