When trying to find an answer to related question I stumbled across this thread and noticed that at the top of the website http://www.morecambehigh.com you have a blue alert banner that appears which says:
“Welcome to our new website! Over the next few weeks we will be bringing in more exciting content and features so please return to us soon. Scroll down to see more content”.
Its a great feature, can you please let me know how you achieved this?
