【已解决】Mac本地搭建绘本查询推荐系统前台页面

折腾了:

【已解决】Mac本地搭建用Flask绘本查询推荐系统后台

后,继续去折腾,mac本地搭建绘本查询系统的前台页面。

暂时先用web页面,后续可以考虑换小程序等其他形式。

先去建git仓库等事情,就不赘述了。

然后就是去开始写代码,画界面了。

根据之前经验,直接用bootstrap的css去画,可以实现基本的不同端的页面适配:

移动端:行内元素紧凑上下显示

PC端:行内元素左右显示

然后去写代码。

先去下载和导入bootstrap

Bootstrap · The most popular HTML, CSS, and JS library in the world.

Download · Bootstrap

再去下载:jQuery

jQuery

然后参考之前代码,先实现基本的从api返回json数据并显示的逻辑:

index.html

.logo{

}

h2{

    text-align: center;

    margin-top: 10px;

    margin-bottom: 10px;

}

h4{

    text-align: center;

    margin-top: 0px;

    margin-bottom: 20px;

}

form {

    text-align: center;

}

效果:

然后继续去添加多行

query result的多行内容

recommend的多行内容

找找bootstrap中,适合:

  • 上下的多个元素的列表

  • 和每行内的内容显示

发现适合的有:

列表:

List group · Bootstrap

Cards · Bootstrap

或:

Media object · Bootstrap

https://getbootstrap.com/docs/4.1/layout/media-object/#media-list

接着就要去:

【已解决】JQuery中如何生成html并替换原先html节点的内容

然后此处发现个问题:

【已解决】bootstrap中panel缺少边框效果

然后继续调试页面布局:

【已解决】bootstrap 4中实现每行左边图片右边基本信息的布局样式

然后继续画页面:

【已解决】html和bootstrap 4中支持点击每行跳转到新页面且传递参数

然后再去优化详情页的显示的布局:

希望在media的下面,显示出description(很多行的描述文字)

参考:

Cards · Bootstrap

https://getbootstrap.com/docs/4.0/components/card/#card-styles
