Learning outcomes

Work on a practice copy, keep filenames lowercase and hyphenated, and create a backup before changing a live website.

Open the relevant project page, file or WordPress screen and confirm you are working on a safe practice copy.
Identify domain, host and certificate responsibilities.
Inspect the result using browser tools or WordPress Preview; do not publish yet.
Check keyboard use, mobile layout, content accuracy, links, images and privacy where applicable.
Confirm that you can avoid unsafe publishing assumptions, then save a clearly named version or backup.

Ian's practical tip: Preview first, test at desktop and mobile sizes, and keep a recoverable copy before publishing.
