STEP 1 · LEARN

How it works

Use em when stress emphasis changes the meaning of a sentence. Semantic structure should describe meaning, not visual appearance.

Correct example
<p>I asked for the <em>final</em> version, not the draft.</p>

em adds stress emphasis to part of a sentence. Moving the emphasis to another word can change what the reader understands.

Common mistake
<p><i>I asked for the final version.</i></p>

i represents text in an alternate voice or category, not stress emphasis. It is not a semantic replacement for em.
