最近把博客的主题换成了Icarus。这个主题不自带版权保护，我决定自己动手加一个。

Step 1. 打开/themes/icarus//languages/zh-CN.yml，添加如下内容：

copyright:
    title: "本文标题: "
    author: "本文作者: "
    link: "原文链接: "
    license_title: "版权声明: "
    date: "发布时间: "
    license_content: "本网站所有文章除特别声明外,均采用 %s 许可协议。非商业转载请注明出处!"

Step 2. 打开/themes/icarus/layout，新建copyright.ejs，内容如下：

<div>
  <ul class="post-copyright">
    <li class="post-copyright-title">
      <strong><%= __('copyright.title') %></strong>
      <a href="<%- config.root %><%- post.path %>" target="_blank" title="本文标题: <%- page.title %>"><%- page.title %></a>
    </li>
    <li class="post-copyright-author">
      <strong><%= __('copyright.author') %> </strong></a>
      <a href="<%- config.root %>" target="_blank" title="本文作者: <%= config.author%>"><%= config.author%></a>
    </li>
    <li class="post-copyright-link">
      <strong><%= __('copyright.link') %> </strong>
      <a href="<%- config.root %><%- post.path %>" target="_blank" title="原文链接: <%- config.url %>/<%- post.path %>"><%- config.url %>/<%- post.path %></a>
    </li>
    <li class="post-copyright-date">
      <strong><%= __('copyright.date') %> </strong></a>
      <a href="/archives" target="_blank" title="发布时间: <%= page.date.format("YYYY-MM-DD  HH:MM")%>"><%= page.date.format("YYYY-MM-DD  HH:MM")%></a>
    </li>
    <li class="post-copyright-license">
      <strong><%= __('copyright.license_title') %>  </strong>
      <%- _p('copyright.license_content', '<a rel="license" href="https://creativecommons.org/licenses/by-nc-nd/4.0/" target="_blank" title="Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)">CC BY-NC-ND 4.0</a>') %>
    </li>
  </ul>
</div>

Step 3. 在/layout/common/article.ejs中添加如下内容（引入copyright.ejs）：

<% const services = has_config('donate') ? get_config('donate') : []; %>
<% if (!index && services.length > 0) { %>
<div class="card">
    <div class="card-content">
        <h3 class="menu-label has-text-centered"><%= __('donate.title') %></h3>
        <div class="buttons is-centered">
            <% for (let service of services) {
                const type = get_config_from_obj(service, 'type');
                if (type !== null) { %>
                <%- _partial('donate/' + type, { type, service }) %>
                <% }
            } %>
        </div>
    </div>
</div>
<% } %>


+ <% if (!index && page.copyright){ %>
+ <%- partial('copyright') %>
<% } %>


<% if (!index && (post.prev || post.next)) { %>
<div class="card card-transparent">
    <div class="level post-navigation is-flex-wrap is-mobile">
        <% if (post.prev){ %>
        <div class="level-start">
            <a class="level level-item has-link-grey <%= !post.prev ? 'is-hidden-mobile' : '' %> article-nav-prev" href="<%- url_for(post.prev.path) %>">
                <i class="level-item fas fa-chevron-left"></i>
                <span class="level-item"><%= post.prev.title %></span>
            </a>
        </div>
        <% } %>
        <% if (post.next){ %>
        <div class="level-end">
            <a class="level level-item has-link-grey <%= !post.next ? 'is-hidden-mobile' : '' %> article-nav-next" href="<%- url_for(post.next.path) %>">
                <span class="level-item"><%= post.next.title %></span>
                <i class="level-item fas fa-chevron-right"></i>
            </a>
        </div>
        <% } %>
    </div>
</div>
<% } %>

最后打开你的博客，大功告成。
