修改Blogdown Webst的字体标题

Question

大家好，这是我关于博客的第一个问题。我想对博客标题进行基本更改。

该博客来自以下链接：

一辉

这是.toml文件：

baseurl = "/"
languageCode = "en-us"
title = "This is the Title I want Change"
theme = "hugo-xmag"
googleAnalytics = ""
disqusShortname = ""
ignoreFiles = ["\\.Rmd$", "_files$", "_cache$"]
preserveTaxonomyNames = true
footnotereturnlinkcontents = "?"
hasCJKLanguage = true
enableEmoji = true
paginate = 6

[permalinks]
    post = "/post/:year/:month/:day/:slug/"

[[menu.main]]
    name = "Home"
    url = "/"
    weight = 1
[[menu.main]]
    name = "About"
    url = "/about/"
    weight = 2
[[menu.main]]
    name = "Categories"
    url = "/categories/"
    weight = 3
[[menu.main]]
    name = "Tags"
    url = "/tags/"
    weight = 4
[[menu.main]]
    name = "Subscribe"
    url = "/index.xml"

[params]
    description = "A website built through Hugo and blogdown."
    summary_length = 300
    github_edit = "https://github.com/yihui/hugo-xmag/edit/master/exampleSite/content/"
    footer = "© [Yihui Xie](https://yihui.name) 2017 | [Github](https://github.com/yihui) | [Twitter](https://twitter.com/xieyihui)"

[params.text]
    back = "← Back to Home"
    edit = "Edit this page →"
    truncated = "…"

该网站上的杂志标题为Blackletter（？），但在.css文件中找不到与此字体相关的任何内容。这是我想要更改的字体。

请帮忙吗？

只要有个主意就好。

谢谢
