<p><a href="/ko/docs/Web/CSS">CSS</a> 속성의 <strong>실제값</strong>은 모든 근사치(approximation)가 적용된 뒤의 <a href="/ko/docs/Web/CSS/used_value">사용값</a>입니다. 예를 들어, 사용자 에이전트는 오직 정수 픽셀값으로 테두리(border)를 렌더링할 수도 있고 테두리의 계산된 폭(width)에 근접하도록 강제할 지도 모릅니다.</p>

<h2 id="Calculating_a_property's_actual_value">Calculating a property's actual value</h2>

<p>The {{glossary("user agent")}} performs four steps to calculate a property's actual (final) value:</p>

<ol>
 <li>First, the <a href="/ko/docs/CSS/specified_value" title="https://developer.mozilla.org/en/CSS/specified_value">specified value</a> is determined based on the result of <a href="/ko/docs/Web/CSS/Cascade">cascading</a>, <a href="/ko/docs/Web/CSS/inheritance" title="en/CSS/inheritance">inheritance</a>, or using the <a href="/ko/docs/Web/CSS/initial_value">initial value</a>.</li>
 <li>Next, the <a href="/ko/docs/Web/CSS/computed_value" title="en/CSS/computed value">computed value</a> is calculated according to the specification (for example, a <code>span</code> with <code>position: absolute</code> will have its computed <code>display</code> changed to <code>block</code>).</li>
 <li>Then, layout is calculated, resulting in the <a href="/ko/docs/Web/CSS/used_value">used value</a>.</li>
 <li>Finally, the used value is transformed according to the limitations of the local environment, resulting in the actual value.</li>
</ol>
