## Usage

While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.

    {{% button href="https://gohugo.io/" %}}Get Hugo{{% /button %}}
    {{% button href="https://gohugo.io/" style="warning" icon="dragon" %}}Get Hugo{{% /button %}}

    {{ partial "shortcodes/button.html" (dict
        "context" .
        "href" "https://gohugo.io/"
        "content" "Get Hugo"
    )}}
    {{ partial "shortcodes/button.html" (dict
      "context" .
      "href" "https://gohugo.io/"
      "style" "warning"
      "icon" "dragon"
      "content" "Get Hugo"
    )}}

Once the button is clicked, it opens another browser tab for the given URL.

### Parameter

Name | Default | Notes
--- | --- | ---
href | <empty> | Either the destination URL for the button or JavaScript code to be executed on click. If this parameter is not set, the button will do nothing but is still displayed as clickable. - if starting with `javascript:` all following text will be executed in your browser - every other string will be interpreted as URL
style | `transparent` | The style scheme used for the button. - by severity: `info`, `note`, `tip`, `warning` - by brand color: `primary`, `secondary`, `accent` - by color: `blue`, `green`, `grey`, `orange`, `red` - by special color: `default`, `transparent`
color | see notes | The CSS color value to be used. If not set, the chosen color depends on the style. Any given value will overwrite the default. - for severity styles: a nice matching color for the severity - for all other styles: the corresponding color

Any given value will overwrite the default. - for severity styles: a nice matching icon for the severity - for all other styles: <empty> If you want no icon for a severity style, you have to set this parameter to `" "` (a non empty string filled with spaces)
iconposition | `left` | Places the icon to the `left` or `right` of the title.
target | see notes | The destination frame/window if href is an URL. Otherwise the parameter is not used. This behaves similar to normal links.

type | see notes | The button type if href is JavaScript. Otherwise the parameter is not used. If the parameter is not given it defaults to `button`
