修改内容区域的宽度

首先启用相应的styl

# Define custom file paths.
# Create your custom files in site directory `source/_data` and uncomment needed files below.
custom_file_path:
  #head: source/_data/head.njk
  #header: source/_data/header.njk
  #sidebar: source/_data/sidebar.njk
  #postMeta: source/_data/post-meta.njk
  #postBodyEnd: source/_data/post-body-end.njk
  #footer: source/_data/footer.njk
  #bodyEnd: source/_data/body-end.njk
  variable: source/_data/variables.styl
  #mixin: source/_data/mixins.styl
  #style: source/_data/styles.styl

编辑主题的 source/_data/variables.styl 文件，新增变量：

// 修改成你期望的宽度
$content-desktop = 700px
// 当视窗超过 1600px 后的宽度
$content-desktop-large = 1050px
