怎麼開啟Blogger的嵌套式留言(threaded comments)? (包含自訂版型怎麼安裝)

嵌套式留言也有人叫階層式留言，總之就是可以回覆留言的功能。

進入Blogger的後台，到你要開啟嵌套式留言的網誌的「設定」中的「其他」裡「允許網誌資訊提供」改成「完整」，然後再把「文章和留言」裡的「留言位置」改成「嵌入」。

如果你使用的是預設版型，一定會出現嵌套式留言，但如果是自訂版型，而且沒有出現的話，必須到後台的「範本」「編輯HTML」修改html。
用搜尋去找到這段
<b:if cond='data:blog.pageType == "item"'>
<b:include data='post' name='comments'/>
</b:if>
並且替換成下面這段
<b:if cond='data:blog.pageType == "static_page"'>
<b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/>
<b:include data='post' name='comments'/>
</b:if>
</b:if>
<b:if cond='data:blog.pageType == "item"'>
<b:if cond='data:post.showThreadedComments'>
<b:include data='post' name='threaded_comments'/>
<b:else/>
<b:include data='post' name='comments'/>
</b:if>
</b:if>
然後「儲存範本」就完成了。
留言的樣式用CSS修改，可以從進入後台的「範本」「自訂」「進階」的「新增CSS」覆寫或加入新的CSS，或是直接在「編輯HTML」增修。
我的CSS是這樣
