However, it should not be used simply to apply italic styling; use the CSS {{cssxref("font-style")}} property for that purpose. Use the {{HTMLElement("cite")}} element to mark the title of a work (book, play, song, etc.). Use the {{HTMLElement("i")}} element to mark text that is in an alternate tone or mood, which covers many common situations for italics such as scientific names or words in other languages. Use the {{HTMLElement("strong")}} element to mark text that has greater importance than surrounding text.</p> + +<h3 id="<i>_vs._<em>"><i> vs. <em></h3> + +<p>New developers are often confused at seeing multiple elements that produce similar results. <code><em></code> and <code><i></code> are a common example, since they both italicize text. What's the difference? Which should you use?</p> + +<p>By default, the visual result is the same. However, the semantic meaning is different. The <code><em></code> element represents stress emphasis of its contents, while the <code><i></code> element represents text that is set off from the normal prose, such a foreign word, fictional character thoughts, or when the text refers to the definition of a word instead of representing its semantic meaning. (The title of a work, such as the name of a book or movie, should use <code><cite></code>.)</p> + +<p>This means the right one to use depends on the situation. Neither is for purely decorational purposes, that's what CSS styling is for.</p> + +<p>An example for <code><em></code> could be: "Just <em>do</em> it already!", or: "We <em>had</em> to do something about it". A person or software reading the text would pronounce the words in italics with an emphasis, using verbal stress.</p> + +<p>An example for <code><i></code> could be: "The <em>Queen Mary</em> 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<em> Queen Mary</em>. Another example for <code><i></code> could be: "The word <em>the</em> is an article".</p> + +<h2 id="Example">Example</h2> + +<p>The <code><em></code> element is often used to indicate an implicit or explicit contrast.</p> + +<pre class="brush: html notranslate"><p> + In HTML 5, what was previously called + <em>block-level</em> content is now called + <em>flow</em> content. +</p></pre> + +<h3 id="Result">Result</h3> + +<p>{{EmbedLiveSample("Example")}}</p> + +<h2 id="Specifications">Specifications</h2> + +<table class="standard-table"> + <thead> + <tr> + <th scope="col">Specification</th> + <th scope="col">Status</th> + <th scope="col">Comment</th> + </tr> + </thead> + <tbody> + <tr> + <td>{{SpecName('HTML WHATWG', 'text-level-semantics.html#the-em-element', '<em>')}}</td> + <td>{{Spec2('HTML WHATWG')}}</td> + <td></td> + </tr> + <tr> + <td>{{SpecName('HTML5 W3C', 'textlevel-semantics.html#the-em-element', '<em>')}}</td> + <td>{{Spec2('HTML5 W3C')}}</td> + <td></td> + </tr> + <tr> + <td>{{SpecName('HTML4.01', 'struct/text.html#h-9.2.1', '<em>')}}</td> + <td>{{Spec2('HTML4.01')}}</td> + <td></td> + </tr> + </tbody> +</table> + +<h2 id="Trình_duyệt_tương_thích">Trình duyệt tương thích</h2> + + + +<p>{{Compat("html.elements.em")}}</p> + +<h2 id="Xem_thêm">Xem thêm</h2> + +<ul> + <li>{{HTMLElement("i")}}</li> +</ul> |
