This question already has an answer here:
I want to give the "italic" button back the "styling" behaviour, rather than the spammy
<em>. I want that button to print a
<i> tag, rather than
<em> tags became popular to spam search engines, but now I want it to be what it is: a styling feature to e.g. change the voice of the narration.
I've got a script to create my own styles, so I'll include the
<em> tag there, to use it as what it REALLY is: EMPHASIS. I'll then style it accordingly (big, bold).
