+          <p>Unicode 是字体在网页端最原始的应用方式，特点是：</p>
+          <ul>
+            <li>支持按字体的方式去动态调整图标大小，颜色等等。</li>
+            <li>默认情况下不支持多色，直接添加多色图标会自动去色。</li>
+          </ul>
+          <blockquote>
+            <p>注意：新版 iconfont 支持两种方式引用多色图标：SVG symbol 引用方式和彩色字体图标模式。（使用彩色字体图标需要在「编辑项目」中开启「彩色」选项后并重新生成。）</p>
