**（1）实现以下功能：**

![这里写图片描述][20160301165633310]

代码附上：

width: 5px;
    height: 35px;
    border: 84px solid;
    border-color: #ffa002 transparent transparent transparent;

--------------------

**（2）如何实现“颜色渐变”这种功能效果图，如下图：**

![这里写图片描述][20160301170540931]  
代码附上：

background: -webkit-linear-gradient(left, #67d41f 24%, #FFFFFF 1%,#FFFFFF 24.5%, #d2d2d2 1% ,#d2d2d2 50%,#FFFFFF 1%,#FFFFFF 50.8%,#D2D2D1 1%,#D2D2D1 75%,#ffffff 1%,#ffffff 75.6%,#d2d2d2 1%,#d2d2d2 99%);

--------------------

**（3）在标题文字后面加图片**

如图所示：
    
    在ul li 的末尾处加入向右的箭头

![这里写图片描述][20160301170754043]

只需在li标签上加入一个css即可：
    
     background: #FFFFFF url(../../img/right-jia.png) center right 18px no-repeat;

--------------------

**（4）改变背景颜色**  /

**1、上下分开**

background: linear-gradient(to bottom, #ffea78 0px, #FFFFFF 100%)repeat-x scroll 0 0 rgba(0, 0, 0, 0);

![这里写图片描述][20160506105617245]

**2、左右分开**

background:linear-gradient(to left, red 100px, yellow 200px);

![这里写图片描述][20160604141513531]

**3、左上角渐变**

background-image:linear-gradient(to left top, red 100px, yellow 200px);

![这里写图片描述][20160604141648735]

--------------------

**（5）文本过长，不换行用省略号显示**

.ellipsis { /**文本过长，不换行用省略号显示*/ overflow: hidden; white-space: nowrap; text-overflow: ellipsis; -o-text-overflow: ellipsis; -icab-text-overflow: ellipsis; -khtml-text-overflow: ellipsis; -moz-text-overflow: ellipsis; -webkit-text-overflow: ellipsis; }
    
    .ellipsis1 { /**多行文本过长，用省略号显示*/ width: 200px; word-break: break-all; display: -webkit-box; -webkit-line-clamp: 1; -webkit-box-orient: vertical; overflow: hidden; }
    
    .ellipsis2 { /**多行文本过长，用省略号显示*/ width: 200px; word-break: break-all; display: -webkit-box; -webkit-line-clamp: 2;//显示的第几行加省略号 -webkit-box-orient: vertical; overflow: hidden; }

demo 附上：

<!DOCTYPE html>
    <html>
    
        <head lang="en">
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width,height = device-height, initial-scale=0,maximum-scale = 2.0,minimum-scale = 1.0,user-scalable = no">
            <title>省略号</title>
    
            <style> .text1 { width: 200px; overflow: hidden; text-overflow: ellipsis; -o-text-overflow: ellipsis; -webkit-text-overflow: ellipsis; -moz-text-overflow: ellipsis; white-space: nowrap; } .text2 { width: 200px; word-break: break-all; display: -webkit-box; -webkit-line-clamp: 2; -webkit-box-orient: vertical; overflow: hidden; } </style>
        </head>
    
        <body>
            <div class="text1">热卖精选：从子频道（服饰鞋包，亲子，居家，美妆）档期里面挑选出来，库存大于30%的高信价比商品list，数量为50个</div>
    
            <br />
    
            <div class="text2">热卖精选：从子频道（服饰鞋包，亲子，居家，美妆）档期里面挑选出来，库存大于30%的高信价比商品list，数量为50个</div>

    word-wrap: break-word;/*在长单词或URL地址内部进行换行。*/
    word-break: normal;/*强制英文单词断行*/
    word-break:break-all;/*允许在单词内换行*/

--------------------

**（8）禁用鼠标Style**

cursor:not-allowed;

--------------------

**（9）CSS3布局**

### **一、display : flex 布局** ###

**1、效果1**

<!DOCTYPE html>
    <html>
    
        <head>
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width,user-scalable=0">
            <title>布局</title>
            <style> body { margin: 0 auto;} .list { display: -webkit-flex; flex-flow: row wrap; -webkit-flex-flow: row wrap; align-items: stretch; -webkit-align-items: stretch; justify-content:center; -webkit-justify-content: center; /* * flex-flow的参数介绍 row ---横向（左向右） column ---竖向（上向下） wrap ---一行显示不完的时候换行 */ } .list div { margin: 5px 0px 0px 0px; width: 40%; height: 100px; line-height: 100px; text-align: center; border: 1px solid red; } </style>
        </head>
    
        <body>
            <div class="list">
                <div>AAA</div>
                <div>BBB</div>
                <div>CCC</div>
                <div>DDD</div>
            </div>
        </body>
    </html>

![这里写图片描述][20160506110744250]  
  
  
**2、效果2**

//css中设置
    .list {
        display: -webkit-flex;
        flex-flow: row;
        -webkit-flex-flow: row;
        align-items: stretch;
        -webkit-align-items: stretch;
        justify-content:center;
        -webkit-justify-content: center;
    }

![这里写图片描述][20160506114006279]

**3、效果3**

**CSS flex 属性**

让所有灵活的项目都带有相同的长度，忽略它们的内容。

<!DOCTYPE html>
    <html>
        <head>
            <meta charset="UTF-8">
            <meta name="viewport" content="width=device-width,user-scalable=0">
            <meta name="apple-mobile-web-app-capable" content="yes">
            <meta name="apple-mobile-web-app-status-bar-style" content="black">
            <title>布局</title>
            <style> body{ margin: 0 auto;} /* flex-flow: row wrap; row横向（左向右）显示 column竖向（上向下）显示 wrap一行显示不完的时候换行 */ div{ border: 1px solid red; height: 200px; } footer { display: -webkit-flex; -webkit-flex-flow: row; -webkit-align-items: stretch; -webkit-justify-content:space-between; /*IE10还不支持*/ display: -ms-flex; -ms-flex-flow: row wrap; -ms-align-items: stretch; -ms-justify-content:space-between; display: flex; flex-flow: row; align-items: stretch; justify-content:space-between; } .col2{ -webkit-flex:1;-moz-flex:1;flex:1} </style>
        </head>
        <body>
            <footer>
                <div style="width:80px;">AAA</div>
                <div class="col2">BBB</div>
                <div style="width:40px;">CCC</div>
            </footer> 
        </body>
    </html>

![这里写图片描述][20160506113631496]

**浏览器支持**

除了 Safari，其他所有主流浏览器都支持 flex 属性。

IE 9 及其之前的版本不支持 flex 属性。IE 10 需要前缀 -ms- 才支持该属性。

详情请查阅W3C规范：[http://www.runoob.com/cssref/css3-pr-flex.html][http_www.runoob.com_cssref_css3-pr-flex.html]

### **二、display : box 布局** ###

实现代码：

<!DOCTYPE html>
    <html>
    
        <head>
            <meta charset="UTF-8">
            <meta name="viewport" id="viewport" content="width=device-width,initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
    
            <title></title>
            <style> body{ margin:0 auto;text-align:center} .test_box{ width:100%;background:#f0f3f9;margin:0 auto} .test_box .list{ width:25%;/*字体：加粗、36px大小，高度80px*/font:700 26px/80px monaco;border:1px solid red} /*关键代码*/ .one{ display:-moz-box;display:-webkit-box;display:-o-box;display:box;-moz-box-pack:start;-webkit-box-pack:start;-o-box-pack:start;box-pack:start} .two{ display:-moz-box;display:-webkit-box;display:-o-box;display:box;-moz-box-pack:end;-webkit-box-pack:end;-o-box-pack:end;box-pack:end} .three{ display:-moz-box;display:-webkit-box;display:-o-box;display:box;-moz-box-pack:center;-webkit-box-pack:center;-o-box-pack:center;box-pack:center} .four{ display:-moz-box;display:-webkit-box;display:-o-box;display:box;-moz-box-pack:justify;-webkit-box-pack:justify;-o-box-pack:justify;box-pack:justify} </style>
        </head>
    
        <body>
            <div class="test_box one">
                <div class="list">1</div>
                <div class="list">2</div>
                <div class="list">3</div>
            </div><br />
            <div class="test_box two">
                <div class="list">4</div>
                <div class="list">5</div>
                <div class="list">6</div>
            </div><br />
            <div class="test_box three">
                <div class="list">7</div>
                <div class="list">8</div>
                <div class="list">9</div>
            </div><br />
            <div class="test_box four">
                <div class="list">10</div>
                <div class="list">11</div>
                <div class="list">12</div>
            </div>
        </body>
    
    </html>

--------------------

**（10）align-items（竖轴上的排列基准）**

flex-start：弹性盒子元素的侧轴（纵轴）起始位置的边界紧靠住该行的侧轴起始边界。

flex-end：弹性盒子元素的侧轴（纵轴）起始位置的边界紧靠住该行的侧轴结束边界。

center：弹性盒子元素在该行的侧轴（纵轴）上居中放置。（如果该行的尺寸小于弹性盒子元素的尺寸，则会向两个方向溢出相同的长度）。

baseline：如弹性盒子元素的行内轴与侧轴为同一条，则该值与’flex-start’等效。其它情况下，该值将参与基线对齐。

stretch：如果指定侧轴大小的属性值为’auto’，则其值会使项目的边距盒的尺寸尽可能接近所在行的尺寸，但同时会遵照’min/max-width/height’属性的限制。
