Feature card
The feature card highlights an action you want people to take or important information on the homepage. It is the first thing a visitor sees. It always includes:
- Title
- Brief description
- Image
- An optional image caption
- Button
The feature card spans the full width of the screen on desktop and mobile. On mobile, the feature card will stack in this order:
- Image
- Image caption
- Title
- Description
- Button
When and how to use it
Use the feature card to catch visitors' attention and highlight the top task or need.
We recommend always using a feature card on your homepage. Place it at the top of the homepage so it appears below the statewide header, site header, and site navigation. The only other thing that may appear above the feature card is a page alert.
Include a concise title, description, image, and one button. Choose an image that’s in harmony with your brand identity, mission, and tone. The minimum image size is 776 x 517 pixels. For best results, use images with this aspect ratio.
How not to use it
Do not use more than one feature card on your homepage.
Do not use the feature card to make an image carousel. Carousels frustrate people more than they help them and do not meet accessibility standards.
Do not put a lot of content in your feature card. Too much content is hard to read. It will also lengthen the feature card and cause awkward whitespace.

The instructions assume familiarity with npm package management tool and Sass.

CDN installation
We recommend using a build system and bundling your CSS for faster performance. If you do not use a build system, you can include the code from our CDN with a link tag.
