Nunjucks syntax

Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (exampe), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.

Usage

By default the vf-hero makes use of the roundels bacground image. To keep the raw struture of the HTML and CSS the same this is applied using a CSS custom property.

The vf-hero can take an image (provided by Design) which should be uploaded to the files site and applied using the custom property available (--vf-hero--bg-image).

IE 11 will get the background colour and the roundels image, it will not paint a different background image if added. This is progressive enhancement.

Content

Content name Usage .yml key
Heading To be used for the heading of the page. vf_hero_heading
Heading HREF To be used as a 'return to home' link for the micro site. vf_hero_heading_href
Subheading Optional content to be used along with the Heading for a terse explainer. vf_hero_subheading
Kicker Optional content that helps define the context of overall content of the page. vf_hero_kicker
Text Optional content that can help explain the page content in a brief paragraph. vf_hero_text
Link Text The text for the hero 'call to action' link. Only works if there is associated Link HREF. vf_hero_link_text
Link HREF The url that the Link Text would be pointing to and opens in the same browser tab. This only works if there is associated Link Text vf_hero_link_href
Content name .yml key CSS classname
Kicker vf_hero_kicker vf-hero__kicker
Heading vf_hero_heading vf-hero__heading
Heading HREF vf_hero_heading_href vf-hero__heading_link
Subheading vf_hero_subheading vf-hero__subheading
Text vf_hero_text vf-hero__text
Link Text vf_hero_link_text vf-hero__link
Link HREF vf_hero_link_href n/a

CSS Custom Properties

--vf-hero--bg-image — this is for the url for the background image. It can either be added, inline if you're writing the HTML, using the .yml data source of vf_hero_image, or by other needs (a input or upload in WordPress, for example).

---vf-hero--bg-image-size — this is to determine the sizing of the background image. As group sites are using the roundel image it needs specific dimensions so that it works. These dimensions are auto 28.5rem. We use a fallback here as background images in vf-hero should be full bleed by default so the fall back in the CSS is for cover — var(---vf-hero--bg-image-size, cover).

Installation info

This repository is distributed with npm. After installing npm, you can install vf-hero with this command.

$ yarn add --dev @visual-framework/vf-hero

Sass/CSS

The style files included are written in Sass. If you're using a VF-core project, you can import it like this:

@import "@visual-framework/vf-hero/index.scss";

Make sure you import Sass requirements along with the modules. You can use a project boilerplate or the vf-sass-starter
