<h2 id="Resumen">Resumen</h2>

<p>La propiedad CSS <code>border-radius</code> permite a los desarrolladores Web definir qué tan redondeadas serán las esquinas. La redondez de cada esquina está definida usando uno o dos valores para el radio que define su forma dependiendo si es un círculo o una elipse.</p>

<p><img alt="Images of CSS3 rounded corners: no rounding, rounding w/ an arc of circle, rounding w/ an arc of ellipse" class="default internal" src="/files/3638/border-radius-sh.png" style="height: 164px; width: 549px;"></p>

<p>El radio se aplica a todo el {{ Cssxref("background") }}, aun si el elemento no tiene bordes; la posición exacta del recorte es definida por la propiedad {{ Cssxref("background-clip") }}.</p>

<p>Esta propiedad es un <a href="/en/CSS/Shorthand_properties" title="en/CSS/Shorthand_properties">atajo</a> para establecer las cuatro propiedades {{ Cssxref("border-top-left-radius") }}, {{ Cssxref("border-top-right-radius") }}, {{ Cssxref("border-bottom-right-radius") }} y {{ Cssxref("border-bottom-left-radius") }}.</p>

<div class="note">As with any shorthand property, individual inherited values are not possible, that is <code>border-radius:0 0 inherit inherit</code>, which would override existing definitions partially. In that case, the individual longhand properties have to be used.</div>

<pre class="twopartsyntaxbox">Formal grammar: [ <var>&lt;length&gt;</var> | <var>&lt;percentage&gt;</var> ]{1,4}  [ / [ <var>&lt;length&gt;</var> | <var>&lt;percentage&gt;</var> ]{1,4}] ?

</pre>

<pre><strong>The syntax of the first radius allows one to four values:</strong>
border-radius: <em>radius</em>
border-radius: <em>top-left-and-bottom-right</em> <em>top-right-and-bottom-left</em>
border-radius: <em>top-left</em> <em>top-right-and-bottom-left</em> <em>bottom-right</em>
border-radius: <em>top-left</em> <em>top-right</em> <em>bottom-right</em> <em>bottom-left</em>

<strong>The syntax of the second radius also allows one to four values</strong>
border-radius: (first radius values) / <em>radius</em>
border-radius: (first radius values) / <em>top-left-and-bottom-right</em> <em>top-right-and-bottom-left</em>
border-radius: (first radius values) / <em>top-left</em> <em>top-right-and-bottom-left</em> <em>bottom-right</em>
border-radius: (first radius values) / <em>top-left</em> <em>top-right</em> <em>bottom-right</em> <em>bottom-left</em>

border-radius: inherit

<ul>
 <li>Dotted and dashed rounded border corners are rendered as solid in Gecko; see {{ bug("382721") }}.</li>
 <li><code>border-radius</code> does not apply to table elements when {{ Cssxref("border-collapse") }} is <code>collapse</code>.</li>
 <li>Old versions of WebKit handle multiple values differently, see below.</li>

 <li>are not supported in older Chrome and Safari versions (it was <a class="external" href="http://trac.webkit.org/changeset/66615">fixed in Sepember 2010</a>)</li>
 <li>are buggy in Opera prior to 11.50</li>
 <li>are implemented in a non-standard way prior to Gecko 2.0 (Firefox 4). <strong>Both</strong> horizontal and vertical radii were relative to the width of the border box.</li>
 <li>are not supported in older versions of iOS (prior to 5) and Android versions (prior to WebKit 532)</li>
</ul>

<h3 id="Gecko_notes">Gecko notes</h3>

<p>In Gecko 2.0 <code>-moz-border-radius</code> was renamed to <code>border-radius</code>; <code>-moz-border-radius</code> was supported as an alias until Gecko 12.0. In order to conform to the CSS3 standard, Gecko 2.0</p>

<ul>
 <li>changes the handling of {{cssxref("&lt;percentage&gt;")}} values to match the specification. You can specify an ellipse as border on an arbitrary sized element just with <code>border-radius: 50%;</code></li>
 <li>makes rounded corners clip content and images (if {{ cssxref("overflow") }}<code>: visible</code> is not set)</li>
</ul>

<div class="note"><strong>Note:</strong> Support for the prefixed version (<code>-moz-border-radius</code>) was removed in Gecko 13.0 {{ geckoRelease("13.0") }}.</div>

<h3 id="WebKit_notes">WebKit notes</h3>

<p>Older Safari and Chrome versions (prior to WebKit 532.5)</p>

 <li>support only <strong>one</strong> value for all 4 corners. For different radii the <a href="/en/CSS/border-top-left-radius#Examples" title="en/CSS/border-top-left-radius#Examples">long form properties</a> must be used</li>
 <li>don't support the slash <code>/</code> notation. If two values are specified, an elliptical border is drawn on all 4 corners
