1. 技术选型
方案:我们采取单独制作移动页面方案
技术:布局采取flex布局
2. 搭建相关文件夹结构
3. 设置视口标签以及引入初始化样式
<meta name="viewport" content="width=device-width, user-scalable=no,
initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<link rel="stylesheet" href="css/normalize.css">
<link rel="stylesheet" href="css/index.css">
4. 常用初始化样式
body {
max-width: 540px;
min-width: 320px;
margin: 0 auto;
font: normal 14px/1.5 Tahoma,"Lucida Grande",Verdana,"Microsoft
Yahei",STXihei,hei;
color: #000;
background: #f2f2f2;
overflow-x: hidden;
-webkit-tap-highlight-color: transparent;
}
搜索外观完成
结构伪类做:二倍图
做法:1.打开PS缩放一半 2.量出需要的图标,在css中设置top和left负值 3.css中将缩放后的大小重新给就是background-size
焦点图
5. 常见模块命名
6. 常见flex布局思路
要设置为主轴为y轴,侧轴居中
利用属性选择器更换背景图片
第一个a要取消下边框
7. 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
原理跟上面是一样的
