遗忘知识点

一、流和截流

1、float：left/right

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>带着小图片</title>
        <style type="text/css">
        *{
            margin:0 auto; padding:0;
            }
        .w{ 
            float:left;
            }     
        </style>
    </head>
    
    <body>
        <div style="604px; height:41px; border:1px solid #e9e9e9;">
        <div class="w">春节</div>
        <div class="w">元宵节</div>
        <div class="w">端午节</div>
        <div class="w">中秋节</div>
        <div class="w">国庆节</div>
        <div style=" 104px; height:41px;"></div>
        </div>
    </body>

不用流的效果

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>带着小图片</title>
        <style type="text/css">
        *{
            margin:0 auto; padding:0;
            }   
        </style>
    </head>
    
    <body>
        <div style="604px; height:41px; border:1px solid #e9e9e9;">
        <div class="w">春节</div>
        <div class="w">元宵节</div>
        <div class="w">端午节</div>
        <div class="w">中秋节</div>
        <div class="w">国庆节</div>
        <div style=" 104px; height:41px;"></div>
        </div>
    </body>

2、截流clear：both

给国庆节截流

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>带着小图片</title>
        <style type="text/css">
        *{
            margin:0 auto; padding:0;
            }
        .w{ 
            float:left;
            }     
        </style>
    </head>
    
    <body>
        <div style="604px; height:41px; border:1px solid #e9e9e9;">
        <div class="w">春节</div>
        <div class="w">元宵节</div>
        <div class="w">端午节</div>
        <div class="w">中秋节</div>
        <div class="w" style="clear:both">国庆节</div>
        <div style=" 104px; height:41px;"></div>
        </div>
    </body>

二、网页title带小图片<link rel="shortcut icon" href=""/>写在head里但不要写在style里

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>带着小图片</title>
        <link  rel="shortcut icon" href="timg1.jpg"/>
    </head>

三、边框透明 border：transparent

    <body>
        <div style="0px; height:0px; border-bottom:50px solid transparent; border-left:50px solid #00F;
 border-right:#FF0 solid 50px; border-top:50px solid #F00;"></div>
    </body>

四、鼠标放上效果会改变hover

    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>带着小图片</title>
        <style type="text/css">
        *{
            margin:0 auto; padding:0;
            }
        .w{ 
            float:left;
            }
        .w:hover{
            background-color:#000;
            color:#FFF;
            }          
        </style>
    </head>
    
    <body>
        <div style="604px; height:41px; border:1px solid #e9e9e9;">
        <div class="w">春节</div>
        <div class="w">元宵节</div>
        <div class="w">端午节</div>
        <div class="w">中秋节</div>
        <div class="w">国庆节</div>
        <div style=" 104px; height:41px;"></div>
        </div>
    </body>

五、旋转 transform:rotate(45deg)；旋转45度

    <body>
        <div style="0px; height:0px; border-bottom:50px solid transparent; 
border-left:50px solid #00F; border-right:#FF0 solid 50px; border-top:50px solid #F00; 
transform:rotate(45deg);">
        </div>
    </body>
