The CSS Properties and Values API allows developers to register custom CSS properties through JavaScript via registerProperty() or in CSS using the at-rule. See Firefox bug 1740530 for more details. This enables compression-friendly color vector fonts with gradients, compositing and blending to be loaded using the CSS rule, or the CSS Font Loading API. This feature provides support for the OpenFont COLRv1 font specification. Note that, as shown below, the feature is only available on Nightly builds (irrespective of whether the preference is set). See Firefox bug 1539075 for more details.
Reject any violations in requirements or recommendations.įirefox supports JPEG XL images if this feature is enabled. 1 (default): Reject violations of requirements, but allow violations of recommendations.0: Accept images with specification violations in both recommendations ("should" language) and requirements ("shall" language), provided they can be safely or unambiguously interpreted.This allows Firefox users to display images that render on some other browsers, even if they are not strictly compliant. The _strictness preference can be used to control the strictness applied when processing AVIF images. See Firefox bug 1280613 and Firefox bug 778617 for more information. This adds the promise-based methods appendBufferAsync() and removeAsync() for adding and removing media source buffers to the SourceBuffer interface. The following experimental features include those found in the WebRTC API, the Web Audio API, the Media Source Extensions API, the Encrypted Media Extensions API, and the Media Capture and Streams API. See Firefox bug 1602129 for our progress on this API. The WebGPU API provides low-level support for performing computation and graphics rendering using the Graphics Processing Unit (GPU) of the user's device or computer. Currently, there are no WebGL extensions being tested by Firefox.
When this preference is enabled, any WebGL extensions currently in "draft" status which are being tested are enabled for use. The hit region API allows you to define an area of your canvas and provides another possibility to expose interactive content on a canvas to accessibility tools. Whether the mouse coordinates are within a particular area on the canvas is a common problem to solve.
You can alternatively use the scroll() functional notation with animation-timeline to indicate that a scrollbar axis in an ancestor element will be used for the timeline.įor more information, see Firefox bug 1807685, Firefox bug 1804573, Firefox bug 1809005, Firefox bug 1676791, Firefox bug 1754897, and Firefox bug 1737918. The longhand and shorthand properties are both available behind the preference. When using the scroll-timeline shorthand property, the order of the property values must be scroll-timeline-name followed by scroll-timeline-axis. The scroll timeline can then be associated with an animation by setting the animation-timeline property to the name value defined using scroll-timeline-name. The scroll-timeline-name and scroll-timeline-axis properties (and the scroll-timeline shorthand property) allow you to specify that a particular scrollbar in a particular named container can be used as the source for a scroll-driven animation. If you're gonna learn one - this is it.Earlier called "scroll-linked animations", a scroll-driven animation depends on the scroll position of a scrollbar instead of time or some other dimension. “GSAP IS the animation library and has been for years.Only with the help of GSAP and this forum was I able to accomplish my project.” “This is by far the fastest and most active community I've ever seen for getting personalized answers to questions.Thomas Aufresne, “I’ve long felt like GSAP is the best kept secret in JavaScript.”

“GSAP is free for most part - the few extra (paid) plugins are a million times worth paying for.”.The simplicity of the GreenSock API makes learning and applying these tools in projects such a dream.” “Every time a new GSAP plugin is introduced, I'm close to bursting from excitement.It seems like I stumble on something new and amazing every time I peek at the docs.”
“The depth of GSAP blows me away like all the time.This the first time I feel this way about a library.” “Reading through the GreenSock docs been amazed like 14 times so far! How can a library be SO complete? Been using that for about 2 years now but man.The whole GSAP platform is, far and away, the best out there for dealing with animation of any sort.”
