I inherited a page full of center tags and blinking marquee text, and I don't know what's safe to remove.
What you'll have at the end
The same page with zero deprecated elements left, a clean validator pass, and a short list of what still needs a style rule.
You need
An old HTML file already in front of you, carrying at least one font, center or marquee tag, and a text editor to change it in.
Not covered
Writing the actual CSS that will style each class you add along the way; that belongs to your CSS work, not to this page's own tags.
Leans on
This page renders fine; validation still fails
Your page already avoids every deprecated tag but still fails the checker for other reasons, like an unclosed tag or a duplicate id.
Rebuild a div-soup page with real semantic landmarks
The deprecated tags are gone, but every section is still a plain div or span with no real landmark meaning.
