This can also be useful for making the element more accessible, which we’ll touch on later. We can add content between the opening and closing tags, which is rendered only when the browser cannot render the canvas. Notice that is not a self-closing tag, like an or. For example, we can give our drawing space a width and height: Also, is easy to update, which makes it ideal for more complex and performance-heavy use cases, like YouTube’s Ambient Mode.Īs you might expect with many HTML elements, accepts attributes. HTML is not limited to presentation we can also make interactive graphics with them that respond to standard mouse and keyboard events.īut SVG can also do most of that stuff, right? That’s true, but is more performant than SVG because it doesn’t require any additional DOM nodes for drawing paths and shapes the way SVG does. Out of the box, a is empty - a blank canvas, if you will - and the aforementioned Canvas and WebGL APIs are used to fill the with content. The HTML element is a container element on which we can draw graphics with JavaScript using its own Canvas API and WebGL API. I prefer to keep things simple and accessible, so this article won’t involve complicated color sampling algorithms, although we will utilize them via different methods.īefore we start writing code, I think it’s a good idea to revisit the HTML Canvas element and see why and how it is used for this little effect. ( Large preview)ĭespite having very little to go on, I decided to reverse-engineer the code and share my process for creating an ambient glow around the videos.
Even if the source code didn’t give me a complete answer, looking into the HTML canvas could be a good starting point. After digging around YouTube’s convoluted DOM tree and source code in DevTools, I hit an obstacle: all the magic was hidden behind the HTML element and bundles of mangled and minified JavaScript code. ( Large preview)Ĭuriosity hit me, and I set out to replicate the effect on my own. The CSS layout has been edited in-browser to make the effect more noticeable, which is why the video player looks a bit off. The background changes from top to bottom, matching the current frame. It is an incredibly subtle effect, especially when the video’s colors are dark and have less contrast against the dark theme’s background. The feature was released sometime in 2022, and YouTube describes it like this: “Ambient mode uses a lighting effect to make watching videos in the Dark theme more immersive by casting gentle colors from the video into your screen’s background.”
Notice the glow effect around the video player. The background around the video would change as the video played, creating a lush glow around the video player, making an otherwise bland background a lot more interesting. I noticed a charming effect on YouTube’s video player while using its dark theme some time ago. Deconstruct YouTube’s “Ambient Mode” feature and learn how HTML and the requestAnimationFrame function are used to create this glowing effect.
