双栏布局

左边固定,右边自适应

1.左边浮动,右边自适应

//html

            

            

            
         


//css

.content{overflow:hidden;height:200px;}
.left{
  display:inline-block;
  float:left;
  width:200px;
  height:200px;
  background:red;
}

.right{
  display:block;
  height:200px;
  background:yellow;
}

 

2.利用定位

//html

       

       

    

//css
 .content{
            position: relative;
        }

        .left{
           display: inline-block;
           height: 200px; 
           width: 200px;
           position: absolue;
           top: 0;
           float: left;
           background: red;
        }   

        .right{
           display: block; 
           height: 200px;
           background: yellow;
           margin-left: 200px; 
        }

3.负margin方法

//html

        

    
    


//css
.left{
         display: inline-block;  
         width: 200px;
         height: 200px;
         margin-left: -100%;
         background: red;
         float: left;
       }   
    
      .content{
          width: 100%;
          float: left;
      }
 
      .right{
          display: block;
         background: yellow;
         margin-left: 200px;
         height: 200px;
      }

4.利用flex布局;

//html

         

         

     

//css
.content{
           display: flex;
       }
       .left{
           width: 200px;
           height: 200px;
           display: inline-block;
           background: red;
       }
       .right{
           flex: 1;
           background: yellow;
       }
