整体思路

1.寻找自己喜欢的图片轮播插件;

2.在首页模板archive.ejs中添加图片轮播代码;

3.引用所需的jq库(主题自带)、js和css;

4.修改配置文件,增加轮播开关和图片替换等功能。

教程开始

</div>
</div>
<div class="hot_post">
<!--热门文章含图片-->
<div class="index-banner">
<a href="<%- theme.plugins.hot_post.post_one %>" target="_blank">
<img src="<%- theme.plugins.hot_post.pic_one %>" style="width: 100%;">
</a>
</div>
<div class="index-banner forpadding">
<a href="<%- theme.plugins.hot_post.post_two %>" target="_blank">
<img src="<%- theme.plugins.hot_post.pic_two %>" style="width: 100%;">
</a>
</div>
</div>
</div>

增加CSS样式和所需图片

  • 把前面网盘里面文件下载,找到img里的箭头图标,放进themes\volantis\source\img
    image-20200821203336667

  • 在themes\volantis\source\css\style.css中,增加代码:

1
2
if hexo-config('plugins.main_banner.enable')
@import '_other/main_banner'
  • themes\volantis\source\css\_other文件夹(没有请新建)里增加文件main_banner.styl,并在其添加如下代码:
