-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 [configuration](https://gohugo.io/getting-started/configuration/) and then you can type emoji shorthand codes directly in content files:
-
-<!-- markdownlint-disable -->
-<!-- spellchecker-disable -->
-
-<span class="no-wrap">{{< emojify ":see_no_evil:" >}} <code>:see_no_evil:</code></span>
-<span class="no-wrap">{{< emojify ":hear_no_evil:" >}} <code>:hear_no_evil:</code></span>
-<span class="no-wrap">{{< emojify ":speak_no_evil:" >}} <code>:speak_no_evil:</code></span>
-
-<!-- spellchecker-enable -->
-<!-- markdownlint-restore -->
-
-The [Emoji cheat sheet](http://www.emoji-cheat-sheet.com/) is a useful reference for emoji shorthand codes.
-
-{{< hint info >}}
-**Info**\
-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.
-{{< /hint >}}
-
-**Example:**
-
-<!-- spellchecker-disable -->
-<!-- prettier-ignore -->
-{{< highlight html "linenos=table" >}}
-.emoji {
-  font-family: Apple Color Emoji, Segoe UI Emoji, NotoColorEmoji, Segoe UI Symbol, Android Emoji, EmojiSymbols;
-}

+
+## Buttons
+
+Buttons are styled links that can lead to local page or external link.
+
+```tpl
+{{</* button relref="/" [class="..."] */>}}Get Home{{</* /button */>}}
+{{</* button href="https://github.com/thegeeklab/hugo-geekdoc" */>}}Contribute{{</* /button */>}}

+{{< button href="https://github.com/thegeeklab/hugo-geekdoc" >}}Contribute{{< /button >}}
+
+## Columns
+
+The Columns shortcode can be used to organize content side-by-side (horizontally) for better readability.
+
+```html
+{{</* columns */>}} <!-- begin columns block -->
+# Left Content
+Dolor sit, sumo unique argument um no ...
+

+
+## Expand
+
+Expand shortcode can help to decrease clutter on screen by hiding part of text. Expand content by clicking on it.
+
+### Example
+
+#### Default
+
+```tpl
+{{</* expand */>}}
+## Markdown content
+Dolor sit, sumo unique ...
+{{</* /expand */>}}
+```
+
+{{< expand >}}
+

+
+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates investiture. Ornateness bland it ex enc, est yeti am bongo detract re.
+{{< /expand >}}
+
+#### With Custom Label
+
+```tpl
+{{</* expand "Custom Label" "..." */>}}
+## Markdown content
+Dolor sit, sumo unique ...
+{{</* /expand */>}}
+```
+
+{{< expand "Custom Label" "..." >}}
+
+##### More markdown
+
+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates

+feud gait, quid exercise emeritus bis e. In pro quints consequent, denim fastidious
+copious quo ad. Stet probates in duo.
+{{< /expand >}}
+
+## Hint
+
+Hint shortcode can be used as hint/alerts/notification block.
+There are four colors to choose: `info`, `ok`, `warning` and `danger`.
+
+```tpl
+{{</* hint [info|warning|danger] */>}}
+**Markdown content**\
+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates investiture.
+ Ornateness bland it ex enc, est yeti am bongo detract re.
+{{</* /hint */>}}

+
+### Example
+
+{{< hint info >}}

+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates investiture.
+Ornateness bland it ex enc, est yeti am bongo detract re.

+{{< hint ok >}}
+**Markdown content**\
+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates investiture.
+Ornateness bland it ex enc, est yeti am bongo detract re.
+{{< /hint >}}
+
+{{< hint warning >}}

+**Markdown content**\
+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates investiture.
+Ornateness bland it ex enc, est yeti am bongo detract re.
+{{< /hint >}}
+
+## Icon
+
+Simple shortcode to include icons from SVG sprites outside of menus.
+
+```tpl
+{{</* icon "thumbs-up" */>}}
+```
+
+### Example
+
+| Result                     | Usage                            |
+| -------------------------- | -------------------------------- |
+| {{< icon "thumbs-up" >}}   | `{{</* icon "thumbs-up" */>}}`   |
+| {{< icon "thumbs-down" >}} | `{{</* icon "thumbs-down" */>}}` |
+| {{< icon "laugh" >}}       | `{{</* icon "laugh" */>}}`       |
+| {{< icon "lemon" >}}       | `{{</* icon "lemon" */>}}`       |
+| {{< icon "moon" >}}        | `{{</* icon "moon" */>}}`        |
+
+## Tabs
+
+Tabs let you organize content by context, for example installation instructions for each supported platform.
+
+```tpl
+{{</* tabs "uniqueid" */>}}
+{{</* tab "macOS" */>}} # macOS Content {{</* /tab */>}}
+{{</* tab "Linux" */>}} # Linux Content {{</* /tab */>}}
+{{</* tab "Windows" */>}} # Windows Content {{</* /tab */>}}
+{{</* /tabs */>}}
+```
+
+### Example
+
+{{< tabs "uniqueid" >}}
+{{< tab "macOS" >}}
+
+#### macOS
+
+This is tab **macOS** content.
+
+Dolor sit, sumo unique argument um no. Gracie nominal id xiv. Romanesque acclimates
