Problem Statement
When would you use <em> vs <i> tag?
Explanation
The em and i tags both make text italic, but they serve different purposes. Understanding when to use each tag shows good knowledge of semantic HTML. The em tag is a semantic tag that indicates emphasis. Use em when you want to stress or emphasize certain words or phrases in a sentence. The emphasis changes the meaning or adds emotional weight to the content. For example, in the sentence 'I really need to finish this', the word 'really' should use em because it emphasizes urgency. Screen readers will often use different voice inflection when reading em tags, helping convey the emphasis to visually impaired users. Search engines may also give slight weight to emphasized text. The i tag is for text that is offset from normal prose without conveying extra emphasis. Use i for technical terms, foreign language phrases, thoughts, ship names, or when you want italic styling for typographical reasons. For example, book titles, scientific names of species, or foreign words like 'bon appétit'. The i tag does not carry semantic emphasis, so screen readers read it normally. Best practices: use em when the emphasis is important for understanding the meaning. Use i for stylistic or conventional italic usage like foreign words or titles. If you need italic text purely for design purposes, use CSS font style italic instead. Understanding these distinctions is important for writing accessible, semantic HTML and is often asked in web development interviews.
