Do I need to add all font styles to the page, if the layout has only regular, bold fonts?

Question

css

Do I need to add all font styles to the page if the layout has only regular, bold ?
If you do not add then:
Where do the styles in the tags come from <i> <b> <strong> <em>?

Answer 1

Depends on whether they will be used. If you have a one-pager without the ability to edit text, or at least styles, you can not add anything other than those that are clearly used. If, for example, you are doing a stretch on the VP and you know that in the text editor for pages and posts, italics, boldness, and something else can be used - connect it.

Answer 2

Not necessary.
