  • CSS3那些常用的效果

    三角形:

    .triangle{
        0;height:0;
        border:10px solid transparent;
        border-top-color:red; //三角形的方向(相反)、颜色
        //border-left:10px solid red;修改大小以及厚度
    }


    //使用伪类来是实现文字后面的箭头
    .triangle{position:relative;}
    .triangle:after,.triangle:before{
      content:'';
      0;
      height:0;
      border:10px solid transparent;
      border-left:10px solid red;
      position:absolute;
      left:52px;
    }
    //如果想使单线条 after、before 的border-left:10px solid #ccc; 再使用伪类即可
    .triangle:before{
      border-left-color:red;//需要设置的颜色
      left:53px;
    }


    内容箭头(用伪类来实现)
      // 箭头 - :before and :after, 一起组成了好看的气泡小箭头

    .tip:before { //div名称
            position: absolute; 
            display: inline-block; 
            border-top: 7px solid transparent; 
            border-left: 7px solid #eee; //箭头放的方向
            border-bottom: 7px solid transparent; 
            border-left-color: rgba(0, 0, 0, 0.2); //设置透明度0-1直接
            right: -8px; 
            top: 20px; 
            content: ''; 
    }
    //背景阴影 
    .tip:after { 
          position: absolute; 
          display: inline-block; 
          border-top: 6px solid transparent; 
          border-left: 6px solid #eee; 
          border-bottom: 6px solid transparent; 
          right: -6px; //偏移像素
          top: 21px; 
          content: ''; 
    }

    css3美化table

    //.bordered table的class
    .bordered {font-family: 'trebuchet MS', 'Lucida sans', Arial;color: #444;} 
    .bordered th {-webkit-box-shadow: 0 1px 0 rgba(255,255,255,.8) inset;-moz-box-shadow:0 1px 0 rgba(255,255,255,.8) inset;box-shadow: 0 1px 0 rgba(255,255,255,.8) inset;/*表格阴影效果*/
            text-shadow: 0 1px 0 rgba(255,255,255,.5);/*文字阴影效果*/background-color: #dce9f9;/*gradient制作表头渐变色*/
            background-image: -webkit-gradient(linear, left top, left bottom, from(#ebf3fc), to(#dce9f9));
            background-image: -webkit-linear-gradient(top, #ebf3fc, #dce9f9);
            background-image: -moz-linear-gradient(top, #ebf3fc, #dce9f9);
            background-image: -ms-linear-gradient(top, #ebf3fc, #dce9f9);
            background-image: -o-linear-gradient(top, #ebf3fc, #dce9f9);
            background-image: linear-gradient(top, #ebf3fc, #dce9f9);
            filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0, startColorstr=#ebf3fc, endColorstr=#dce9f9);
            -ms-filter: "progid:DXImageTransform.Microsoft.gradient (GradientType=0, startColorstr=#ebf3fc, endColorstr=#dce9f9)";
    }
    .bordered th:first-child {-moz-border-radius: 6px 0 0 0;-webkit-border-radius: 6px 0 0 0;border-radius: 6px 0 0 0;}
    .bordered th:last-child {-moz-border-radius: 0 6px 0 0;-webkit-border-radius: 0 6px 0 0;border-radius: 0 6px 0 0;}
    .bordered tr:last-child td:first-child {-moz-border-radius: 0 0 0 6px;-webkit-border-radius: 0 0 0 6px;border-radius: 0 0 0 6px;}
    .bordered tr:last-child td:last-child {-moz-border-radius: 0 0 6px 0;-webkit-border-radius: 0 0 6px 0;border-radius: 0 0 6px 0;}
