+title: Emoji Support
+date: 2023-02-01
+author: Hugo Authors
+description: Guide to emoji usage in Hugo
+tags:
+  - emoji
+---
+
+Emoji can be enabled in a Hugo project in a number of ways. 
+<!--more-->
+The [`emojify`](https://gohugo.io/functions/emojify/) function can be called directly in templates or [Inline Shortcodes](https://gohugo.io/templates/shortcode-templates/#inline-shortcodes). 
+
+To enable emoji globally, set `enableEmoji` to `true` in your site's `config.toml`. You can type emoji shorthand codes directly in content files; e.g.
+
+`:see_no_evil:` :see_no_evil: `:hear_no_evil:` :hear_no_evil: `:speak_no_evil:` :speak_no_evil:
+
+I :heart: Hugo! 😁
+
+The [Emoji cheat sheet](http://www.emoji-cheat-sheet.com/) is a useful reference for emoji shorthand codes.
+
+***
+
+**N.B.** The above steps enable Unicode Standard emoji characters and sequences in Hugo, however the rendering of these glyphs depends on the browser and the platform. To style the emoji you can either use a third party emoji font or a font stack; e.g.
+
+{{< highlight css >}}
+.emoji {
+  font-family: Apple Color Emoji, Segoe UI Emoji, NotoColorEmoji, Segoe UI Symbol, Android Emoji, EmojiSymbols;
+}
+{{< /highlight >}}
+
+{{< css.inline >}}
+<style>
+.emojify {
+	font-family: Apple Color Emoji, Segoe UI Emoji, NotoColorEmoji, Segoe UI Symbol, Android Emoji, EmojiSymbols;
+	font-size: 2rem;
+	vertical-align: middle;
+}
+@media screen and (max-width:650px) {
+  .nowrap {
+    display: block;
+    margin: 25px 0;
+  }
+}
+</style>
+{{< /css.inline >}}

+
+## Image
+
+You can use the following syntax to include an image. Path of the image should be relative to the `index.md` file.
+
+```markdown
+![Landscape](1.jpg)
+```
+
+![Landscape](1.jpg)
+
+You can also include image from external sources.

+
+## Blockquotes
+
+The blockquote element represents content that is quoted from another source, optionally with a citation which must be within a `footer` or `cite` element, and optionally with in-line changes such as annotations and abbreviations.
+
+### Blockquote without attribution
+
+> You can use Markdown syntax within a blockquote, like **bold**,  _italics_, [links](https://gohugo.io/), `code`.
+
+### Blockquote with attribution
+
+> Don't communicate by sharing memory, share memory by communicating.<br>
+> — <cite>Rob Pike[^1]</cite>

+## Tables
+
+Tables aren't part of the core Markdown spec, but Hugo supports them out-of-the-box.
+
+   Name | Age
+--------|------
+    Bob | 27
+  Alice | 23
+
+### Markdown within tables
+
+| Italics   | Bold     | Code   |
+| --------  | -------- | ------ |
+| *italics* | **bold** | `code` |
+
+## Code Blocks
+
+### Code block with backticks

+title: Math Typesetting - use Mathematical notation in blog posts
+date: 2023-04-01
+description: A brief guide to setup KaTeX
+math: true
+---
+
+Mathematical notation in a Hugo project can be enabled by using
+[third party JavaScript libraries](https://github.com/hugo-sid/hugo-blog-awesome/blob/main/layouts/partials/helpers/katex.html).
+
+<!--more-->
+
+In this example we will be using [KaTeX](https://katex.org/).
+
+- To enable KaTeX globally, set the parameter `math` to `true` in a project's
+  configuration file as follows.
+  - `config.toml`
+    ```toml
+    [params]
+      math = true
+    ```
+  - `config.yaml`
+    ```yaml
+    params:
+      math: true
+    ```
+- To enable KaTeX on a per page basis, include the parameter `math: true` in
+  Front Matter of Markdown content file as follows.
+
+  ```
+  ---
+  math: true
+  ---
+  ```
+
+**Note:** The online reference of
+[Supported TeX Functions](https://katex.org/docs/supported.html) is a helpful resource.
+
+### Examples
+
+- Block math:
+
+  $$
+  \varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } }
+  $$
+
+- Inline math:
+
+  This is an inline polynomial: $5x^2 + 2y -7$.
