<header><h1><strong>: The Strong Importance element</h1></header><div class="section-content"><p>The <code><strong></code> <a href="../index">HTML</a> element indicates that its contents have strong importance, seriousness, or urgency. Browsers typically render the contents in bold type.</p></div>

<div class="section-content"><iframe class="interactive is-tabbed-shorter-height" height="200" src="https://interactive-examples.mdn.mozilla.net/pages/tabbed/strong.html" title="MDN Web Docs Interactive Example" loading="lazy"></iframe></div>

<div class="section-content">
<p>The <code><strong></code> element is for content that is of "strong importance," including things of great seriousness or urgency (such as warnings). This could be a sentence that is of great importance to the whole page, or you could merely try to point out that some words are of greater importance compared to nearby content.</p> <p>Typically this element is rendered by default using a bold font weight. However, it should <em>not</em> be used to apply bold styling; use the CSS <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight"><code>font-weight</code></a> property for that purpose. Use the <a href="b"><code><b></code></a> element to draw attention to certain text without indicating a higher level of importance. Use the <a href="em"><code><em></code></a> element to mark text that has stress emphasis.</p> <p>Another accepted use for <code><strong></code> is to denote the labels of paragraphs which represent notes or warnings within the text of a page.</p>
</div>
<h3 id="b_vs._strong"><b> vs. <strong></h3>
<div class="section-content">
<p>It is often confusing to new developers why there are so many ways to express the same thing on a rendered website. <a href="b"><code><b></code></a> and <code><strong></code> are perhaps one of the most common sources of confusion, causing developers to ask "Should I use <code><b></code> or <code><strong></code>? Don't they both do the same thing?"</p> <p>Not exactly. The <code><strong></code> element is for content that is of greater importance, while the <code><b></code> element is used to draw attention to text without indicating that it's more important.</p> <p>It may help to realize that both are valid and semantic elements in HTML and that it's a coincidence that they both have the same default styling (boldface) in most browsers (although some older browsers actually underline <code><strong></code>). Each element is meant to be used in certain types of scenarios, and if you want to bold text for decoration, you should instead actually use the CSS <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/font-weight"><code>font-weight</code></a> property.</p> <p>The intended meaning or purpose of the enclosed text should be what determines which element you use. Communicating meaning is what semantics are all about.</p>
</div>
<h3 id="em_vs._strong"><em> vs. <strong></h3>
<div class="section-content">
<p>Adding to the confusion is the fact that while HTML 4 defined <code><strong></code> as indicating a stronger emphasis, HTML 5 defines <code><strong></code> as representing "strong importance for its contents." This is an important distinction to make.</p> <p>While <code><em></code> is used to change the meaning of a sentence as spoken emphasis does ("I <em>love</em> carrots" vs. "I love <em>carrots</em>"), <code><strong></code> is used to give portions of a sentence added importance (e.g., "<strong>Warning!</strong> This is <strong>very dangerous.</strong>") Both <code><strong></code> and <code><em></code> can be nested to increase the relative degree of importance or stress emphasis, respectively.</p>
