Alert box has accessibility issues, this update address those with new css for alert box adding an underline. Alert also gets indexed by search engine, a new property is added to the alert box to disable search indexing.
Noted after first long term public test of alert message on sdstate.edu, during which normal site crawlers identified accessibility issues, and users noted descriptive text under auto complete contains alert dialog text.
Search result text and alert message banner displayed site wide during campus closures and emergencies.
Crawler indexed content because flags were not given to stop it doing so, and accessibility issues were unnoticed until tested.
Added new css file alert.css that contains two properties to add underlines to close and open message link, and all links generically in text of message. Added property in template file for alert block that disables search engine crawl.
