It requests the browser to call a user-supplied callback function before the next repaint. </p> <p> The frequency of calls to the callback function will generally match the display refresh rate. The most common refresh rate is 60hz, (60 cycles/frames per second), though 75hz, 120hz, and 144hz are also widely used. <code>requestAnimationFrame()</code> calls are paused in most browsers when running in background tabs or hidden <a href="/en-US/docs/Web/HTML/Element/iframe"><code><iframe></code></a>s, in order to improve performance and battery life. </p> <div class="notecard note"> <p> <strong>Note:</strong> Your callback function must call <code>requestAnimationFrame()</code> again if you want to animate another frame. <code>requestAnimationFrame()</code> is one-shot. </p> </div> <div class="notecard warning"> <p> <strong>Warning:</strong> Be sure always to use the first argument (or some other method for getting the current time) to calculate how much the animation will progress in a frame — <strong>otherwise, the animation will run faster on high refresh-rate screens</strong>.

The timestamp is a decimal number, in milliseconds, but with a minimal precision of 1 millisecond. For <code>Window</code> objects (not <code>Workers</code>), it is equal to <a href="/en-US/docs/Web/API/AnimationTimeline/currentTime" title="document.timeline.currentTime"><code>document.timeline.currentTime</code></a>. This timestamp is shared between all windows that run on the same agent (all same-origin windows and, more importantly, same-origin iframes) — which allows synchronizing animations across multiple <code>requestAnimationFrame</code> callbacks.

The element moves at a speed of 0.1px/ms to the right, so its relative position (in CSS pixels) can be calculated in function of the time elapsed since the start of the animation (in milliseconds) with <code>0.1 * elapsed</code>. The element's final position is 200px (<code>0.1 * 2000</code>) to the right of its initial position. </p> <div class="code-example"><div class="example-header"><span class="language-name">js</span></div><pre class="brush: js notranslate"><code>const element = document.getElementById("some-element-you-want-to-animate"); let start; function step(timestamp) { if (start === undefined) { start = timestamp; } const elapsed = timestamp - start; // Math.min() is used here to make sure the element stops at exactly 200px const shift = Math.min(0.1 * elapsed, 200); element.style.transform = `translateX(${shift}px)`; if (shift < 200) { requestAnimationFrame(step); } } requestAnimationFrame(step); </code></pre></div> <p> The following three examples illustrate different approaches to setting the zero point in time, the baseline for calculating the progress of your animation in each frame. If you want to synchronize to an external clock, such as <a href="/en-US/docs/Web/API/BaseAudioContext/currentTime"><code>BaseAudioContext.currentTime</code></a>, the highest precision available is the duration of a single frame, 16.67ms @60hz. The callback's timestamp argument represents the end of the previous frame, so the soonest your newly calculated value(s) will be rendered is in the next frame. </p> <p> This example waits until the first callback executes to set <code>zero</code>. If your animation jumps to a new value when it starts, you must structure it this way. If you do not need to synchronize to anything external, such as audio, then this approach is recommended because some browsers have a multi-frame delay between the initial call to <code>requestAnimationFrame()</code> and the first call to the callback function. </p> <div class="code-example"><div class="example-header"><span class="language-name">js</span></div><pre class="brush: js notranslate"><code>let zero; requestAnimationFrame(firstFrame); function firstFrame(timestamp) { zero = timestamp; animate(timestamp); } function animate(timestamp) { const value = (timestamp - zero) / duration; if (value < 1) { element.style.opacity = value; requestAnimationFrame((t) => animate(t)); } else element.style.opacity = 1; } </code></pre></div> <p> This example uses <a href="/en-US/docs/Web/API/AnimationTimeline/currentTime" title="document.timeline.currentTime"><code>document.timeline.currentTime</code></a> to set a zero value before the first call to <code>requestAnimationFrame</code>. <code>document.timeline.currentTime</code> aligns with the <code>timestamp</code> argument, so the zero value is equivalent to the 0th frame's timestamp. </p> <div class="code-example"><div class="example-header"><span class="language-name">js</span></div><pre class="brush: js notranslate"><code>const zero = document.timeline.currentTime; requestAnimationFrame(animate); function animate(timestamp) { const value = (timestamp - zero) / duration; // animation-timing-function: linear if (value < 1) { element.style.opacity = value; requestAnimationFrame((t) => animate(t)); } else element.style.opacity = 1; } </code></pre></div> <p> This example animates using <a href="/en-US/docs/Web/API/Performance/now"><code>performance.now()</code></a> instead of the callback's timestamp value. You might use this to achieve slightly higher synchronization precision, though the extra degree of precision is variable and not much of an increase.

The\n callback's timestamp argument represents the end of the previous frame, so the soonest\n your newly calculated value(s) will be rendered is in the next frame.\n</p>\n<p>\n This example waits until the first callback executes to set <code>zero</code>. If your animation\n jumps to a new value when it starts, you must structure it this way. If you do not need to\n synchronize to anything external, such as audio, then this approach is recommended because\n some browsers have a multi-frame delay between the initial call to <code>requestAnimationFrame()</code>\n and the first call to the callback function.\n</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">js</span></div><pre class=\"brush: js notranslate\"><code>let zero;\nrequestAnimationFrame(firstFrame);\nfunction firstFrame(timestamp) {\n zero = timestamp;\n animate(timestamp);\n}\nfunction animate(timestamp) {\n const value = (timestamp - zero) / duration;\n if (value < 1) {\n element.style.opacity = value;\n requestAnimationFrame((t) => animate(t));\n } else element.style.opacity = 1;\n}\n</code></pre></div>\n<p>\n This example uses <a href=\"/en-US/docs/Web/API/AnimationTimeline/currentTime\" title=\"document.timeline.currentTime\"><code>document.timeline.currentTime</code></a> to set a zero value\n before the first call to <code>requestAnimationFrame</code>. <code>document.timeline.currentTime</code>\n aligns with the <code>timestamp</code> argument, so the zero value is equivalent to the\n 0th frame's timestamp.\n</p>\n<div class=\"code-example\"><div class=\"example-header\"><span class=\"language-name\">js</span></div><pre class=\"brush: js notranslate\"><code>const zero = document.timeline.currentTime;\nrequestAnimationFrame(animate);\nfunction animate(timestamp) {\n const value = (timestamp - zero) / duration; // animation-timing-function: linear\n if (value < 1) {\n element.style.opacity = value;\n requestAnimationFrame((t) => animate(t));\n } else element.style.opacity = 1;\n}\n</code></pre></div>\n<p>\n This example animates using <a href=\"/en-US/docs/Web/API/Performance/now\"><code>performance.now()</code></a> instead of the callback's\n timestamp value.
