Theme NexT Canvas Nest 主题next画布嵌套

canvas-nest.js for NexT.

Install

Step 1 → Go to Hexo dir

Change dir to Hexo directory. There must be scaffolds, source, themes and other directories:

$ cd hexo
$ ls
scaffolds  source  themes  _config.yml  package.json

Step 2 → Create footer.swig

Create a file named footer.swig in hexo/source/_data directory (create _data directory if it does not exist).

Edit this file and add the following content:

<script color="0,0,255" opacity="0.5" zIndex="-1" count="99" src="https://cdn.jsdelivr.net/npm/canvas-nest.js@1/dist/canvas-nest.js"></script>

You can customize these options.

Step 3 → Set it up

In the NexT _config.yml, uncomment footer under the custom_file_path section.

# Define custom file paths.
