Feature Request

I think it is a good idea to add font size item to melody.yml
they are similar to "theme-color" item

是的，强烈建议加上字体大小的自定义配置

You can change the font size via CSS (put in the source). Load it through hexo injecter. You could save the file in scripts folder and in javascript (*.js or *.mjs)
