歡迎使用Markdown編輯器

你好！這是你第一次使用 Markdown編輯器 所展示的歡迎頁。如果你想學習如何使用Markdown編輯器, 可以仔細閱讀這篇文章，瞭解一下Markdown的基本語法知識。

新的改變

我們對Markdown編輯器進行了一些功能拓展與語法支持，除了標準的Markdown編輯器功能，我們增加了如下幾點新功能，幫助你用它寫博客：

全新的界面設計 ，將會帶來全新的寫作體驗；
在創作中心設置你喜愛的代碼高亮樣式，Markdown 將代碼片顯示選擇的高亮樣式 進行展示；
增加了 圖片拖拽 功能，你可以將本地的圖片直接拖拽到編輯區域直接展示；
全新的 KaTeX數學公式 語法；
增加了支持甘特圖的mermaid語法¹ 功能；
增加了 多屏幕編輯 Markdown文章功能；
增加了 焦點寫作模式、預覽模式、簡潔寫作模式、左右區域同步滾輪設置 等功能，功能按鈕位於編輯區域與預覽區域中間；
增加了 檢查列表 功能。

功能快捷鍵

撤銷：Ctrl/Command + Z
重做：Ctrl/Command + Y
加粗：Ctrl/Command + B
斜體：Ctrl/Command + I
標題：Ctrl/Command + Shift + H
無序列表：Ctrl/Command + Shift + U
有序列表：Ctrl/Command + Shift + O
檢查列表：Ctrl/Command + Shift + C
插入代碼：Ctrl/Command + Shift + K
插入鏈接：Ctrl/Command + Shift + L
插入圖片：Ctrl/Command + Shift + G

合理的創建標題，有助於目錄的生成

直接輸入1次#，並按下space後，將生成1級標題。
輸入2次#，並按下space後，將生成2級標題。
以此類推，我們支持6級標題。有助於使用TOC語法後生成一個完美的目錄。

如何改變文本的樣式

強調文本 強調文本

加粗文本 加粗文本

標記文本

~~刪除文本~~

引用文本

H₂O is是液體。

2¹⁰ 運算結果是 1024.

插入鏈接與圖片

居中並且帶尺寸的圖片:

當然，我們爲了讓用戶更加便捷，我們增加了圖片拖拽功能。

如何插入一段漂亮的代碼片

去博客設置頁面，選擇一款你喜歡的代碼片高亮樣式，下面展示同樣高亮的 代碼片.

// An highlighted block
var foo = 'bar';

生成一個適合你的列表

創建一個表格

一個簡單的表格是這麼創建的：

項目	Value
電腦	$1600
手機	$12
導管	$1

設定內容居中、居左、居右

使用:---------:居中
使用:----------居左
使用----------:居右

第一列	第二列	第三列
第一列文本居中	第二列文本居右	第三列文本居左

SmartyPants

SmartyPants將ASCII標點字符轉換爲“智能”印刷標點HTML實體。例如：

TYPE	ASCII	HTML
Single backticks	`'Isn't this fun?'`	‘Isn’t this fun?’
Quotes	`"Isn't this fun?"`	“Isn’t this fun?”
Dashes	`-- is en-dash, --- is em-dash`	– is en-dash, — is em-dash

創建一個自定義列表

Markdown: Text-to-HTML conversion tool
Authors: John; Luke

如何創建一個註腳

一個具有註腳的文本。²

註釋也是必不可少的

Markdown將文本轉換爲 HTML。

KaTeX數學公式

您可以使用渲染LaTeX數學表達式 KaTeX:

Gamma公式展示 $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ 是通過歐拉積分

$\Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt\,.$

你可以找到更多關於的信息 LaTeX 數學表達式here.

新的甘特圖功能，豐富你的文章

關於 甘特圖 語法，參考這兒,

UML 圖表

可以使用UML圖表進行渲染。 Mermaid. 例如下面產生的一個序列圖：:

這將產生一個流程圖。:

關於 Mermaid 語法，參考這兒,

FLowchart流程圖

我們依舊會支持flowchart的流程圖：

關於 Flowchart流程圖 語法，參考這兒.

導出與導入

導出

如果你想嘗試使用此編輯器, 你可以在此篇文章任意編輯。當你完成了一篇文章的寫作, 在上方工具欄找到 文章導出 ，生成一個.md文件或者.html文件進行本地保存。

導入

如果你想加載一篇你寫過的.md文件或者.html文件，在上方工具欄可以選擇導入功能進行對應擴展名的文件導入，
繼續你的創作。
