I read that I shouldn’t use b or i to bold or italicize, but rather use CSS properties of strong and em. Can you please explain why and tell me if I should ever use b or i? When, then,will this rule apply?

You can have different CSS for different media. One such is where the browser reads out the page. While you can apply emphasis or strong emphasis when saying something you can’t say a word in bold or italic.
There are conventions for particular things to appear in italic or bold when written down.
Ship names - “The Queen Mary sailed last night.”
Foreign words and Latin taxonomy “Homo sapiens”
References to a specific word “The word the is an article”

Another example would be foreign words, like ad hoc, which are often italicized by convention, but which you wouldn’t actually emphasize when speaking them. That’s when I use
Often in articles there’s a convention to make technical terms either bold or italic—especially the first time they are mentioned. That would be a good time for
i, though they often end up as
em just because that’s how things like WordPress output them (which is a pity).
