Naming and Path
Create a new file named YYYY-MM-DD-TITLE.EXTENSION and put it in the _posts/ of the root directory. Please note that the EXTENSION must be one of md and markdown.
Front Matter
Basically, you need to fill the Front Matter as below at the top of the post:
1
2
3
4
5
6
---
title: TITLE
date: YYYY-MM-DD HH:MM:SS +/-TTTT
categories: [TOP_CATEGORIE, SUB_CATEGORIE]
tags: [TAG] # TAG names should always be lowercase
---
Note: The posts’ layout has been set to
postby default, so there is no need to add the variable layout in Front Matter block.
Timezone of date
In order to accurately record the release date of a post, you should not only setup the timezone of _config.yml but also provide the the post’s timezone in field date of its Front Matter block. Format: +/-TTTT, e.g. +0800.
Categories and Tags
The categories of each post is designed to contain up to two elements, and the number of elements in tags can be zero to infinity. For instance:
1
2
categories: [Animal, Insect]
tags: [bee]
Table of Contents
By default, the Table of Contents (TOC) is displayed on the right panel of the post. If you want to turn it off globally, go to _config.yml and set the value of variable toc to false. If you want to turn off TOC for specific post, add the following to post’s Front Matter:
1
2
3
---
toc: false
---
Comments
Similar to TOC, the Disqus comments is loaded by default in each post, and the global switch is defined by variable comments in file _config.yml . If you want to close the comment for specific post, add the following to the Front Matter of the post:
1
2
3
---
comments: false
---
Mathematics
For website performance reasons, the mathematical feature won’t be loaded by default. But it can be enabled by:
1
2
3
---
math: true
---
Mermaid
Mermaid is a great diagrams generation tool. To enable it on your post, add the following to the YAML block:
1
2
3
---
mermaid: true
---
Then you can use it like other markdown language: surround the graph code with ```mermaid and ```.
Images
Preview image
If you want to add an image to the top of the post contents, specify the url and alt attribute for the image:
1
2
3
4
5
---
image:
src: /path/to/image/file
alt: image alternative text
---
Image caption
Add italics to the next line of an image，then it will become the caption and appear at the bottom of the image:
1
2
_Image Caption_
Image size
You can specify the width (and height) of a image with width:
1
{: width="400"}
Image position
By default, the image is centered, but you can specify the position by using one of class normal , left and right. For example:
Normal position
Image will be left aligned in below sample:
1
{: .normal}
Float to the left
1
{: .left}
Float to the right
1
{: .right}
Limitation: Once you specify the position of an image, it is forbidden to add the image caption.
Image shadow
The screenshots of the program window can be considered to show the shadow effect, and the shadow will be visible in the light mode:
1
{: .shadow}
CDN URL
If you host the images on the CDN, you can save the time of repeatedly writing the CDN url by assigning the variable img_cdn of _config.yml file:
1
img_cdn: https://cdn.com
Once img_cdn is assigned, the CDN url will be added to the path of all images (images of site avatar and posts) starting with /.
For instance, when using images:
1
The parsing result will automatically add the CDN prefix https://cdn.com before the image path:
1
<img src="https://cdn.com/path/to/flower.png" alt="The flower">
Pinned Posts
You can pin one or more posts to the top of the home page, and the fixed posts are sorted in reverse order according to their release date. Enable by:
1

---
pin: true
