I have a page with list of items. each item is a link to go to the specific item info page. on that page there's a button called 'Delete'. so when a user click on it, this item is deleted and the user is taken back to the previous page. since the 'Delete' button is a button and not a link, i'm not sure how accessible is to navigate the user a way from the page he was on.
when the user is taken back, there's a banner saying "item blah blah was deleted'. is that enough? do i need to warn the user BEFORE he goes back to the previous page?
