<i> vs. <em>
It is often confusing to new developers why there are so many elements to express emphasis on some text. <i> and <em> are perhaps one of the most common. Why use
<i></i>? They produce exactly the same result, right?
Not exactly. The visual result is, by default, the same - both tags render its content in italics. But the semantic meaning is different. The
<em> tag represents stress emphasis of its contents, while the <i> tag represents text that is set off from the normal prose, such as the name of a movie or book, a foreign word, or when the text refers to the definition of a word instead of representing its semantic meaning.
An example for
<em> could be: "Just do it already!", or: "We had to do something about it". A person or software reading the text would pronounce the words in italics with an emphasis.
An example for
<i> could be: "The
sailed last night". Here, there is no added emphasis or importance on the word "Queen Mary". It is merely indicated that the object in question is not a queen named Mary, but a ship named
. Another example for
<i> could be: "The word the is an article".
