    myuw-banner

    A component for displaying slightly-interruptive messages via a banner below the top app bar.

    Getting Started

    Include the component as follows:

    <!-- import the module -->
    <script type="module" src="https://cdn.my.wisc.edu/@myuw-web-components/myuw-banner@latest/myuw-banner.min.mjs"></script>
    
    <!-- fallback for browsers without ES2015 module support -->
    <script nomodule src="https://cdn.my.wisc.edu/@myuw-web-components/myuw-banner@latest/myuw-banner.min.js"></script>
    
    <myuw-banner
      message="MyUW"
      icon=""
      action-label=""
      action-aria-label=""
      action-url=""
      learn-more-aria-label=""
      learn-more-url=""
    ></myuw-banner>

    Note: The evergreen "latest" version can be used for convenience, but in production settings it is recommended to use the latest release version specifically, and upgrade only after testing!

    Configurable properties via attributes

    • message: Sets the message to display in the banner
    • icon: Sets an icon to go with the message (optional)
    • action-label: Sets the text for the rightmost button (take action/confirmation)
    • action-aria-label: Sets the aria label for the action button. Whereas a label like "Sign up" might make little sense out of context, an ARIA label like "Sign up for a vaccination appointment" clarifies what one is signing up for.
    • action-url: Sets the url to go to when the confirming button is clicked (required)
    • learn-more-aria-label: Sets the aria-label for the secondary button. This addresses the usability problem that for a typical user a label like "Learn more" might be sufficient because the context is visually apparent from the placement of the button, but for a user consuming the links out of context (e.g., jumping between links in a screen reader browser), a label like "Learn more" prompts the question "Learn more about what???". This ARIA label is a chance to make it apparent what it is one would learn more about. A reasonable value for this might be "Learn more about making a COVID-19 vaccination appointment." (optional; required if learn-more-url is set)
    • learn-more-url: Sets the href for the secondary button. (optional: if not set, button does not appear)

    Styling the banner

    MyUW app bar exposes custom CSS properties so users can change some of its styles.

    • --myuw-banner-bg: Sets the banner's background color
    • --myuw-on-banner: Sets the text color of banner text
    • --myuw-anchor-color: Used for the button and icon colors (also used to set link colors)
    • --myuw-button-transparency: Used for the on-hover background color for buttons

    For more information about CSS variables and how they work with MyUW Web Components, reference the styles component

    How to use custom CSS properties

    Add the following selector to your CSS:

    myuw-banner {
      --myuw-banner-bg: #c5050c;
      --myuw-on-banner: #fff;
    }

    Development and contribution

    To run the demo app locally and test the component, run the following commands:

    $ npm install
    $ npm start

    Releasing

    To release a new version:

    • Pick an appropriate version number, semantically versioning.
      • Backwards-compatible bugfix? patch version.
      • Backwards-compatible new or changed feature? minor version.
      • Breaking change of any kind? major version.
    • Ensure package.json and package-lock.json reflect this version, and that there's a tag for the version pushed to the canonical git repository. (One good way to do this is npm version {type} and then pushing the tag.)
    • npm publish to publish the version as now described in package.json
    • tada! once the version publishes to npm, unpkg picks it up, making it available by named version and as latest.
    • Ensure the CHANGELOG.md reflects this version and its release date.
