Key points
Bold only one piece of text per paragraph and don't overdo it by bolding long sections of text.
Use italics for titles of books, films, videos, and radio and TV programs.
Bold important safety information.
Try to consistently bold the same kind of information within all articles – for example, phone numbers.
Use bolding to highlight key facts that we genuinely want people to extract from the page:
During this time, your family can be a secure emotional base where your child feels loved and accepted, no matter what’s going on in the rest of their life.
But don't overdo it with bolding. If there's too much bolding, the bolding loses it effectiveness as a highlighting method. For example, you don't have to bold something in every paragraph. Also avoid bolding long phrases or sections of text if possible.
Punctuation that follows bold text as part of a sentence should not be bolded:
Hearing and speech: hearing is the ability to hear. [note that the colon is NOT bolded]
But a sentence that is entirely bold concludes with bold punctuation of the full stop:
Hearing is the ability to hear. [note that the full stop IS bolded]
Do use italics for:
book titles
titles of movies, videos, and radio and TV programs
latin names of medical terms for germs – for example, Staphylococcus aureus.
Do not use italics in article titles.
