1.项目概述

1.1.项目演示

  1. 运行 “饿了么前端网页项目” ,演示页面效果。
  2. 本项目参照 “饿了么官网网页版”制作,演示饿了么官网效果。饿了么网页版:http://h5.ele.me/
  3. 本项目中的首页,完全按照“饿了么网页版”实际效果制作,相似度达到99%。
  4. 本项目中的其它页面,专注于完成一个“点餐业务线”功能,所以其它页面效果会有适当的删减。

    2.部分相关知识点讲解

    2.1.移动端开发之viewport

    2.1.1.问题的提出

    移动端屏幕尺寸多变,不像PC端屏幕那样统一。这样就造成在移动端显示网页时,由于尺寸问题,会出现显示不下网页,从而出现横向滚动条现象。 为了解决这个问题,出现了viewport(屏幕视口)的概念。

    2.1.2.解决方案

    viewport有三种:
  1. layout viewport(布局视口):网页实际尺寸,或者说,网页实际有多大,layout viewport就有多大。
  2. ideal viewport(理想视口):移动设备理想viewport,也就是实际屏幕尺寸,根据机型的不同,尺寸也不尽相同。
  3. visualviewport(视觉视口):用户看到的视口区域

使用viewport就可以解决上述问题: 先将网页放入layout viewport中,然后在将layout viewport等比例缩小到ideal viewport中。 这样就能保证:无论什么样的网页,都能在手机屏幕上显示,而且没有横向滚动条。
WEB前端-项目实战课件 - 图3

2.1.3.总结

移动端网页开发时,都要加上这样一段代码:

  1. <meta name="viewport" content="width=device-width, initial-scale=1">

width就是网页实际尺寸,也就是layout viewport。 device-width就是屏幕实际尺寸,也就是ideal viewport。 所以,width=device-width就是将layout viewport按照ideal viewport实际尺寸来显示。

2.2. 弹性布局(弹性盒子)

一个元素的display属性值设置为flex,那么这个元素中的子元素,就会遵循弹性布局的规则。

display:flex  /*flex是flexible box的缩写*/

此时,这个元素就可以称为是一个弹性布局容器(弹性容器),它内部的子元素,将只按照弹性布局的规则来排列和对齐,以前的float、clear、块状与内联、vertical-align属性都不能用了。

2.2.1.重要概念:主轴与侧轴

弹性布局中的一个重要概念:主轴与侧轴: 弹性盒子中默认存在两根轴,一个是水平方向的主轴,一个是垂直方向的侧轴。
WEB前端-项目实战课件 - 图4

注意点:

  1. 主轴的开始位置叫做 main start、 结束位置叫做 main end;
  2. 侧轴的开始位置叫做cross start、结束位置叫做cross end;
  3. 侧轴永远垂直于主轴;

2.2.2.flex-direction样式

flex-direction属性就是用来设置主轴方向的。

flex-direction:row        /*子元素沿主轴方向排列,也就是水平方向。 row为默认值*/
flex-direction:column     /*子元素沿侧轴方向排列,也就是垂直方向。*/

一个完整的例子:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
        <style>
            body{
                display: flex;           /*将body设置为弹性布局*/
                flex-direction: column;  /*这里设置为侧轴方向排列*/
            }
            .son{
                width: 100px;
                height: 100px;
                border: solid 2px #f90;
                background-color: yellow;
            }
        </style>
    </head>
    <body>
        <div class="son">1</div>
        <div class="son">2</div>
        <div class="son">3</div>
        <div class="son">4</div>
        <div class="son">5</div>
    </body>
</html>

总结:

  1. 在弹性容器中,子元素想要水平方向排列,那就在弹性盒子中设置:flex-direction:row
  2. 在弹性容器中,子元素想要垂直方向排列,那就在弹性盒子中设置:flex-direction:column
  3. 在弹性容器中,以前的“块状元素独占一行”,“内联元素不独占一行”,“元素水平排列时需要浮> 动”等等规则,一律不再有效。

2.2.3.flex-wrap样式

由于弹性布局中的子元素能自动伸缩,所以,当父容器此次小于子元素整体尺寸时,子元素不会自动换行,而是自动收缩。

body{
    display: flex;
}

WEB前端-项目实战课件 - 图5
那么,如果想要让子元素自动换行,可以使用flex-wrap:wrap

body{
    display: flex;
    flex-wrap: wrap;   /*当弹性布局容器尺寸小于所以子元素尺寸时,子元素会自动换行*/
}

总结:

  1. 在弹性盒子中,默认子元素不换行,即使是容器宽度不够时,子元素也不换行,只是宽度缩小。
  2. 如果在父容器宽度不够时想要自动换行,那么设置:flex-wrap:wrap

2.2.4.justify-content样式

以主轴方向为例:子元素水平方向排列后,默认依次靠左排列。 如果想让子元素居中、居右等,那么就可以设置justify-content样式。值有五种:

  1. flex-start(默认):左对齐。
  2. flex-end:右对齐。
  3. center:居中。
  4. space-between:两端对齐,子元素之间间距都相等。
  5. space-around:每个子元素两侧的间距相等。所以子元素之间间距比子元素到边框 间距大一倍。

例如:

body{
    display: flex;
    justify-content: space-between;    /*两端对齐,子元素之间间距都相等。*/
}

总结:在弹性盒子中,子元素主轴对齐方式使用justify-content来设置

2.2.5.align-items与align-content样式

以主轴方向为例:子元素水平方向排列后,如果想让子元素垂直居中,那么就可以设置align-items样式。常用值有三种:

  1. flex-start(默认):上对齐。
  2. flex-end:下对齐。
  3. center:居中。
    html,body{
     height: 100%;               /*html与body的高度默认为0,所以要设置高度*/
    }
    body{
     display: flex;
     flex-wrap: wrap;           /*如果允许换行,那么换行后,多行元素中的每一行也会垂直居中*/
     justify-content: center;
     align-items: center;       /*不论是一行,还是多行,都会垂直居中*/
    }
    

再来看align-content样式: align-content样式对单行没有效果,对多行有效果,而且是将多行整体作为一个整体附加效果的。

总结:在弹性盒子中,子元素侧轴对齐方式可以使用align-items或align-content

  1. align-items对单行和多行都有效,align-content对单行无效。
  2. 在多行中,align-items让每一行都在各自范围内垂直居中。 align-content将多行作为一个整> 体,然后居中。

2.2.6.flex样式

如果想让每个子元素所占空间不一致,那么可以使用flex给子元素分配空间。 使用flex时要注意一下两点:

  1. flex样式是设置在子元素上的。
  2. 如果设置了flex,那就说明要给子元素按比例分配空间,因此width与height就失效了。

实例1:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
        <style>
            html,body{
                height: 100%;
            }
            body{
                display: flex;
            }
            .son{
                width: 100px;
                height: 100px;
                border: solid 2px #f90;
                background-color: yellow;
            }
        </style>
    </head>
    <body>
        <div class="son" style="flex:1;">1</div>
        <div class="son" style="flex:1;">2</div>
        <div class="son" style="flex:2;">3</div>
        <div class="son" style="flex:2;">3</div>
    </body>
</html>

上面实例中:flex样式后跟1个值:表示子元素所占空间的比例。 三个div的宽度分别是窗口宽度的:1/4、1/2、1/4
实例2:

<!-- 第一个div的宽度是400px,是不变的。第二个和第三个div将剩下宽度按比例分配:1/3、2/3 -->
<body>
    <div class="son" style="flex:0 0 400px;">1</div>
    <div class="son" style="flex:1;">2</div>
    <div class="son" style="flex:2;">3</div>
</body>

WEB前端-项目实战课件 - 图6
上面实例中:flex样式后跟3个值:

  1. 第一个值:子元素尺寸自动放大值
  2. 第二个值:子元素尺寸自动缩小值
  3. 第三个值:子元素尺寸(”auto”或”%”、”px”、”em” 或任何其他长度单位的数字。)

例如:

  • 0 1 auto(默认):父元素尺寸变化时,子元素不放大,只缩小,尺寸自动充满。
  • 1 1 auto: 父元素尺寸变化时,子元素自动放大缩小,尺寸自动充满。
  • 0 0 300px: 父元素尺寸变化时,子元素不放大缩小,尺寸固定。

    总结:可以使用flex让一行内的所有子元素自动撑满窗口宽度。而且每个子元素的宽度可以按比例> 进行分配。

2.3.视口尺寸

视口:在PC端,指浏览器的可视区域;在移动端,指Viewport 中的 Layout Viewport。 视口尺寸常用的有以下2个: vw : 1vw 等于视口宽度的1% vh : 1vh 等于视口高度的1% 实际应用中,可以使用vw,实现元素宽度和高度成比例自动缩放。

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
        <style>
            div{
                width: 30vw;
                height: 20vw;
                background-color: blue;
                color: #fff;
                font-size: 5vw;
            }
        </style>
    </head>
    <body>
        <div>
            我能够随着屏幕自适应
        </div>
    </body>
</html>

2.4.边框盒子模型

CSS3之前的盒子模型,可以说是content-box型盒子,即宽和高为内容。 CSS3之后新增了一的盒子模型,可以说是border-box型盒子,即宽和高为边框。 那么,使用box-sizing属性可以设置盒子模型类型。

div{
    width: 200px;
    height: 200px;
    box-sizing: border-box;   /*值有两个: border-box:边框盒子; content-box:内容盒子(默认)*/
    padding: 30px;
    background-color: orange;
    border: solid 30px blue;
    margin: 50px;
}

总结:使用了边框盒子,就可以任意设置内边距、边框了,而且不用担心会改变盒子的总体尺寸。

2.5. 字体图标

一般来说,在网页上使用字体图标可以有三种方式:自定义CSS图标、第三方字体图标、转义字符

2.5.1.自定义CSS图标

下面是一个自定义CSS小图标:定位图标(icon.css文件)

/**
 * location 定位小图标 
 * 说明:使用div标签,加上icon-location类样式即可。
 *       但需要放置在一个容器中,调整容器大小,图标能自适应容器大小。
 * 示例:
 * <div class="icon-location-box">
 *     <div class="icon-location"></div>
 * </div>
 */
.icon-location {
    position: relative;
    width: 100%;                         /*先画一个正方形*/
    height: 100%;
    border-radius: 50% 50% 50% 0;        /*然后将三个角变成圆角*/
    background: #fff;
    transform: rotate(-45deg);           /*最后,旋转45度*/
}
.icon-location:after {        
    content: '';
    width: 40%;
    height: 40%;
    margin: 30% 0 0 29%;
    background-color: #0097FF;
    position: absolute;
    border-radius: 50%;
}

使用时:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
        <link href="css/icon.css" rel="stylesheet">
        <style>
            .icon-location-box{
                width: 50px;
                height: 50px;
            }
        </style>
    </head>
    <body bgcolor="#0000FF">
        <div class="icon-location-box">
            <div class="icon-location"></div>
        </div>
    </body>
</html>

2.5.2.使用第三方字体图标库

第三方字体图标库有很多很多,比如常用的: Font Awesome:https://fontawesome.dashgame.com/ (直接在官网上进行讲解)

2.5.3.使用转义字符

HTML转义字符:http://114.xixik.com/character/ (直接在此网站上进行讲解)

3.项目实战

3.1.搭建项目结构

  • css文件夹: 存放css文件。
  • framework文件夹: 存放第三方库文件,以及一些共通的css文件(自定义css图标、css重置)
  • img: 存放图片
  • js: 存放js文件

CSS重置:reset.css文件中的内容:

/***************** CSS重置 *******************/
html,body,div,span,h1,h2,h3,h4,h5,h6,ul,ol,li,p{
    margin: 0;
    padding: 0;
}
html,body{
    width: 100%;
    height: 100%;
    font-family: "微软雅黑";
}
ul,ol{
    list-style:none;
}
a{
    text-decoration: none;
}
