Hero component

npm version


The vf-hero component is to be used as a visual queue and page header. As needed, it can take a kicker, heading, sub-heading, text content, and a 'call to action' link.


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

The default variant is equivalent to vf-hero--1200 and the recommended image size is 3000 by 1000 pixels.


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

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).

Internet Explorer support

IE 11 will get the background colour and the "roundels" image. Under the approach of progressive enhancement, IE 11 will not paint a different background image if added.

EMBL usage

For EMBL sites, 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).
