If you leave it inside a paragraph, it will produce an inline expression, just like $$ E = mc^2 $$.
+In fact, you can also use a single dollar sign `$` to create inline formulas, such as `$ E = mc^2 $`, which will render as $ E = mc^2 $. This approach provides the same effect during TeX-based compilation, but visually it appears slightly less bold compared to double-dollar signs `$$`, making it blend more naturally with surrounding text.

+## Mermaid
+
+This theme supports creating diagrams directly in markdown using [Mermaid](https://mermaid.js.org/). Mermaid enables users to render flowcharts, sequence diagrams, class diagrams, Gantt charts, and more. Simply embed the diagram syntax within a mermaid code block.
+
+To create a Gantt chart, you can use the following syntax:
+
+````markdown
+```mermaid
+gantt
+ dateFormat YYYY-MM-DD
+ title A Gantt Diagram
+
+ section Section
+ Task A :a1, 2025-01-01, 30d
+ Task B :after a1, 20d
+ Task C :2025-01-10, 12d
+```
+````
+
+And here’s how it will be rendered:
+
+```mermaid
+gantt
+ dateFormat YYYY-MM-DD
+ title A Gantt Diagram
+
+ section Section
+ Task A :a1, 2025-01-01, 30d
+ Task B :after a1, 20d
+ Task C :2025-01-10, 12d
+```
+
+Similarly, you can also use it to create beautiful class diagrams:
+
+````
+```mermaid
+classDiagram
+direction LR
+ class Animal {
+ +String species
+ +int age
+ +makeSound()
+ }
+ class Dog {
+ +String breed
+ +bark()
+ }
+ class Cat {
+ +String color
+ +meow()
+ }
+ class Bird {
+ +String wingSpan
+ +fly()
+ }
+ class Owner {
+ +String name
+ +int age
+ +adoptAnimal(Animal animal)
+ }
+
+ Animal <|-- Dog
+ Animal <|-- Cat
+ Animal <|-- Bird
+ Owner "1" --> "0..*" Animal
+
+ Dog : +fetch()
+ Cat : +purr()
+ Bird : +sing()
+```
+````
+
+It will be presented as:
+
+```mermaid
+classDiagram
+direction LR
+ class Animal {
+ +String species
+ +int age
+ +makeSound()
+ }
+ class Dog {
+ +String breed
+ +bark()
+ }
+ class Cat {
+ +String color
+ +meow()
+ }
+ class Bird {
+ +String wingSpan
+ +fly()
+ }
+ class Owner {
+ +String name
+ +int age
+ +adoptAnimal(Animal animal)
+ }
+
+ Animal <|-- Dog
+ Animal <|-- Cat
+ Animal <|-- Bird
+ Owner "1" --> "0..*" Animal
+
+ Dog : +fetch()
+ Cat : +purr()
+ Bird : +sing()
+```
+
+With Mermaid, you can easily add clear and dynamic diagrams to enhance your blog content.

+## Diff2Html
+
+This theme also supports integrating [Diff2Html](https://github.com/rtfpessoa/diff2html), a tool that beautifully renders code differences (diffs) directly in markdown. Diff2Html is ideal for showcasing code changes, allowing you to clearly present additions, deletions, and modifications. It’s perfect for code reviews, documentation, and tutorials where step-by-step code changes need to be highlighted—you can even introduce changes across multiple files at once.

+## Leaflet

+[Leaflet](https://leafletjs.com/) is created by Ukrainian software engineer [Volodymyr Agafonkin](https://agafonkin.com/), allowing interactive maps to be embedded in webpages. With support for [GeoJSON data](https://geojson.org/), Leaflet allows you to highlight specific regions, making it easy to visualize geographical information in detail.
+
+You can use the following code to load map information on [OpenStreetMap](https://www.openstreetmap.org/):

+
+Here’s an example of a JSON-style configuration that creates a bar chart in Chart.js:
+
+````
+```chartjs
+{
+ "type": "bar",
+ "data": {
+ "labels": ["2017", "2018", "2019", "2020", "2021"],
+ "datasets": [
+ {
+ "label": "Population (millions)",
+ "data": [12, 15, 13, 14, 16],
+ "backgroundColor": "rgba(54, 162, 235, 0.6)",
+ "borderColor": "rgba(54, 162, 235, 1)",
+ "borderWidth": 1
+ }
+ ]
+ },
+ "options": {
+ "scales": {
+ "y": {
+ "beginAtZero": true
+ }
+ }
+ }
+}
+```
+````
+
+The rendered bar chart illustrates population data from 2017 to 2021:

+
+[ECharts](https://echarts.apache.org/) is a powerful visualization library from [Apache](https://www.apache.org/) that supports a wide range of interactive charts, including more advanced types such as scatter plots, heatmaps, and geographic maps.

+## TikZ
+
+[TikZ](https://tikz.net/) is a powerful LaTeX-based drawing tool powered by [TikZJax](https://tikzjax.com/). You can easily port TikZ drawings from papers, posters, and notes. For example, we can use the following code to illustrate Euler’s formula $ e^{i \theta} = \cos \theta + i \sin \theta $:

+## Typograms
+
+[Typograms](https://google.github.io/typograms/) are a way of combining text and graphics to convey information in a clear and visually engaging manner. Typograms are particularly effective for illustrating simple diagrams, charts, and concept visuals where text and graphics are closely integrated. The following example demonstrates a simple Typogram:
+
+````
+```typograms
+ ___________________
+ / /|
+ /__________________/ |
+ | | |
+ | Distill | |
+ | | |
+ | | /
+ |__________________|/
+```
+````
+
+The rendered output is shown below：
+
+```typograms
+ ___________________
+ / /|
+ /__________________/ |
+ | | |
+ | Distill | |
+ | | |
+ | | /
+ |__________________|/
