+
+Buttons are styled links that can lead to local page or external link.
+
+```tpl

+## 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 >}}

+{{< /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.

+{{< /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" >}}
+

+
