Hexo-Next – Change Fonts & Enable Code Copy

The Next theme version used here is 7.8.0.

First, locate the file:

1	/themes/next/_config.yml

Search for the keyword font.
⚠️ Important: You must set enable inside font to true, because the default value is false.
If you only modify the family without enabling it, the font change will not take effect — so make sure you don’t miss this step.

If the font family is sourced from an external platform, you also need to configure the host.

font:
  enable: true

  # Uri of fonts host, e.g. https://fonts.googleapis.com (Default).
  host: 

  # Font options:
  # `external: true` will load this font family from `host` above.
  # `family: Times New Roman`. Without any quotes.
  # `size: x.x`. Use `em` as unit. Default: 1 (16px)

  # Global font settings used for all elements inside <body>.
  global:
    external: true
    family: Noto Serif SC
    size:

  # Font settings for site title (.site-title).
  title:
    external: true
    family: Noto Serif SC
    size:

  # Font settings for headlines (<h1> to <h6>).
  headings:
    external: true
    family: Noto Serif SC
    size:

  # Font settings for posts (.post-body).
  posts:
    external: true
    family: Noto Serif SC

  # Font settings for <code> and code blocks.
  codes:
    external: true
    family: Source Code Pro

Enable Copy Button for Code Blocks

In the same _config.yml file, locate the following configuration section.

Set copy_button.enable to true to enable the copy feature.

When show_result is set to true, a checkmark will be shown after copying.
The style option controls the appearance of the copy button. Choose based on your preference.

codeblock:
  # Code Highlight theme
  # Available values: normal | night | night eighties | night blue | night bright | solarized | solarized dark | galactic
  # See: https://github.com/chriskempson/tomorrow-theme
  highlight_theme: night eighties

  # Add copy button on codeblock

    # Show text copy result.
    show_result: true
    # Available values: default | flat | mac
    style: mac
