技术选型
方案：采用单独制作移动页面方案
技术：布局采用flex布局
body样式
通常要设置最大宽度，最小宽度，水平居中，字体设置，背景颜色以及相关初始化
body {max-width: 540px;min-width: 320px;margin: 0 auto;font: normal 14px/1.5 Tahoma,"Lucida Grande",Verdana,"Microsoft Yahel",STXihei,hei;color: #000;background-color: #f2f2f2;overflow-x: hidden;-webkit-tap-highlight-color: transparent;
}搜索模块
搜索模块是一个固定定位，它与父亲没有关系，只与视口有关，所以设定位置为水平居中时，要以视口为标准。固定定位的盒子要有宽度
.search-index {/* 固定定位跟父亲没有关系 它与视口有关(屏幕) */display: flex;position: fixed;top: 0;left: 50%;transform: translateX(-50%);/* 固定的盒子要有宽度 */width: 100%;height: 44px;max-width: 540px;min-width: 320px;
}- 左边为自适应，右边小盒子定宽定高，这就需要用到flex布局，给右边盒子顶宽定高，左边盒子不设置宽高，直接设置flex:1;即可,记得给父元素加flex属性，display:flex;
- 右边小盒子由两个部分组成，可以只使用一个元素，给这个元素设置伪元素即可
- 给伪元素设置宽度时，要先将其变为块级元素，之后给伪元素设置背景图即可，二倍背景图(精灵图)要先将原图等比例缩小一半，测定坐标，记得也要将原图设置background-size:原宽的一半 auto;
- 设置文字水平居中以及颜色大小等等
<a href="" class="user">我 的</a>.user {width: 44px;height: 44px;background-color: aquamarine;font-size: 12px;text-align: center;color: #2eaae0;
}
.user::before {content: "";display: block;width: 23px;height: 23px;background: url(../images/sprite.png) no-repeat -59px -194px;background-size: 104px auto;margin: 4px auto -3px;
}- 左边搜索区域里的搜索也可用伪元素，同样使用精灵图，但使用伪元素时要将伪元素设置为块级元素，右边的文字就会被挤下去，此时伪元素可采取定位，之后将设置search的padding-left即可
- 文字垂直居中使用line-height时，最好不要和高度相同，而要减去边框的高度，因为使用的时CSS3模型，边框不会扩大盒子，此时的内容区会变小，若使用原高度文字会偏下
<div class="search-index"><div class="search">目的地/景点/酒店</div><a href="" class="user">我 的</a> </div>.search {position: relative;height: 26px;border: 1px solid #ccc;flex: 1;align-self: center;margin: 0 10px;border-radius: 5px;font-size: 12px;color: #666;line-height: 24px;padding-left: 25px;box-shadow: 0 2px rgba(0,0,0,.2);border-top: 1px solid #ccc;border-bottom: 1px solid #ccc;
}
.search::before {position: absolute;top: 5px;left: 5px;content: "";display: block;width: 15px;height: 15px;background: url(../images/sprite.png) no-repeat -59px -279px;background-size: 104px auto;
}焦点图区域
直接添加图片即可，但因为上面搜索区域是固定定位，不占据位置，下方图片某部分会被搜索区域覆盖住，因此要设置焦点图区域的padding-left使其往下方移动
local-nav
常见flex布局思路
<ul class="local-nav"><li><a href="" title="景点 玩乐"><span class="local-nav-icon"></span><span>景点 玩乐</span></a></li><li><a href="" title="景点 玩乐"><span class="local-nav-icon"></span><span>景点 玩乐</span></a></li><li><a href="" title="景点 玩乐"><span class="local-nav-icon"></span><span>景点 玩乐</span></a></li><li><a href="" title="景点 玩乐"><span class="local-nav-icon"></span><span>景点 玩乐</span></a></li><li><a href="" title="景点 玩乐"><span class="local-nav-icon"></span><span>景点 玩乐</span></a></li></ul>.local-nav {display: flex;height: 64px;background-color: #fff;border-radius: 8px;margin: 3px 4px;
}
.local-nav li {flex: 1;
}
.local-nav a {display: flex;flex-direction: column;font-size: 12px;/* 侧轴居中 */align-items: center;
}
.local-nav-icon {margin-top: 8px;width: 32px;height: 32px;background: url(../images/localnav_bg.png) no-repeat 0 0;background-size: 32px;}
主导航栏
- 将nav设置为flex，三个子元素设置flex:1;这样三个子元素会平分宽度
- 第二个和第三个孩子也设置为flex，将主轴改为column，再让里面的儿子设置为flex;1;就可实现垂直平分
- 接着向里面添加背景图和内容即可
背景线性渐变
语法1:
background:linear-gradient(起始方向，颜色1，颜色2，...);background:-webkit-linear-gradient(left, red，blue);
background:-webkit-linear-gradient(left top,red,blue);
- 背景渐变必须添加浏览器私有前缀
- 起始方向可以是:方位名词或者度数，如果省略默认就是top
<style>div {width: 600px;height: 200px;/* 背景渐变必须添加浏览器私有前缀 */background: -webkit-linear-gradient(left,red,blue);}</style> <body><div></div> </body>
三个子盒子就用到了线性渐变。
<div class="nav"><div class="nav-common"><div class="nav-items"><a href="">海外酒店</a></div><div class="nav-items"><a href="">海外酒店</a><a href="">特价酒店</a></div><div class="nav-items"><a href="">海外酒店</a><a href="">特价酒店</a></div></div><div class="nav-common"><div class="nav-items"><a href="">海外酒店</a></div><div class="nav-items"><a href="">海外酒店</a><a href="">特价酒店</a></div><div class="nav-items"><a href="">海外酒店</a><a href="">特价酒店</a></div></div><div class="nav-common"><div class="nav-items"><a href="">海外酒店</a></div><div class="nav-items"><a href="">海外酒店</a><a href="">特价酒店</a></div><div class="nav-items"><a href="">海外酒店</a><a href="">特价酒店</a></div></div></div>.nav {border-radius: 8px;margin: 0 4px 3px;overflow: hidden;
}.nav-common {display: flex;height: 88px;background-color: #666;
}.nav-common .nav-items {flex: 1;display: flex;flex-direction: column;
}
.nav-items a {flex: 1;text-align: center;line-height: 44px;color: #fff;font-size: 14px;/* 文字阴影 */text-shadow: 1px 1px rgba(0,0,0,.2);
}
.nav-items a:nth-child(1) {border-bottom: 1px solid #fff;
}
.nav-items:nth-child(1) a {border: 0;background: url(..//images/hotel.png) no-repeat bottom center;background-size: 121px auto;
}
.nav-items:nth-child(-n+2) {border-right: 1px solid #fff;
}
.nav-common:nth-child(1) {background: -webkit-linear-gradient(left,#fa5a55,#fa994d);
}
.nav-common:nth-child(2) {margin: 3px 0;background: -webkit-linear-gradient(left,#4b90ed,#53bced);
}
.nav-common:nth-child(3) {background: -webkit-linear-gradient(left,#34c2a9,#6cd559);
}侧导航栏
- 侧导航栏的制作与local-nav相似，只是多了一个换行，将父级加上flow-wrap:wrap;
- 子元素设置为flex:20%(相对于父元素)
- 子元素里和local-nav里的子元素一样，将a设置为flex，将主轴改为column，侧边居中即可
<div class="subnav-entry"><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li><li><a href=""><span class="subnav-entry-icon"></span><span>电话费</span></a></li></div>
.subnav-entry {display: flex;border-radius: 8px;background-color: #fff;margin: 0 4px;flex-wrap: wrap;
}.subnav-entry li {/* 里面的盒子可以写百分比 相对于父级来说的 */flex: 20%;
}.subnav-entry a {display: flex;flex-direction: column;align-items: center;
}.subnav-entry-icon {width: 28px;height: 28px;margin-top: 4px;background: url(../images/subnav-bg.png) no-repeat;background-size: 28px auto;
}
销售模块
- 分为头部和身体，头部热门活动因为SEO优化先写文字，再利用首行缩进将文字隐藏，利用定位添加伪元素设置背景，伪元素添加定位之后就变成行内块元素了，故不需要将其变为块级元素。
- 三角的CSS制作，显示出右边框和下边框，瞬时针旋转45度即可。
- 下面图片区域使用flex布局，里面两个a元素，a元素均flex:1;就能水平平均分布。添加边框即可
