Flip html5 remove functions2/28/2023 The strings 'fast' and 'slow' can be supplied to indicate durations of 200 and 600 milliseconds, respectively.Īs of jQuery 1.4.3, an optional string naming an easing function may be used. When these properties reach 0 after a hiding animation, the display style property is set to none to ensure that the element no longer affects the layout of the page.ĭurations are given in milliseconds higher values indicate slower animations, not faster ones. toggle() method animates the width, height, and opacity of the matched elements simultaneously. When a duration, a plain object, or a single "complete" function is provided. If an element has a display value of inline, then is hidden and shown, it will once again be displayed inline. The display property is saved and restored as needed. If the element is initially displayed, it will be hidden if hidden, it will be shown. The matched elements will be revealed or hidden immediately, with no animation, by changing the CSS display property. The following example shows how a slide-out menu can be created using animation best practices.įirst, create the menu as shown in sample code below. The transform methods appropriate for most touch screen projects are “2D” transform methods as shown in the table below.ĭefines a 2D transformation using a matrix of six valuesĭefines a 2D translation moving the element along the X- and the Y-axisĭefines a 2D translation moving the element along the X-axisĭefines a 2D translation moving the element along the Y-axisĭefines a 2D scale transformation by changing the element's width and heightĭefines a 2D scale transformation by changing the element's widthĭefines a 2D scale transformation by changing the element's heightĭefines a 2D rotation where the angle is specified in the parameterĭefines a 2D skew transformation along the X- and the Y-axisĭefines a 2D skew transformation along the X-axisĭefines a 2D skew transformation along the Y-axis.The transform style property has a value of a function that changes the element.This CSS style will create smoother animations than using left/top/bottom/right properties. The “transform” CSS style property will best utilize the GPU. Using CSS is preferred because it uses native code when using the CPU, and many of the operations will be instead processed by the GPU, which is the ideal processor for graphical elements. Therefore, when writing JavaScript for CH5, it is recommended not to create any animations that involve modifying the elements in JavaScript, including the requestAnimationFrame() function. Crestron touch screens also do not have a dedicated GPU (Graphics Processing Unit), so the hardware does not provide the same acceleration required for smooth animations that is possible on a workstation. As a result, JavaScript is slower than native languages. JavaScript is an interpreted language with an interpreter in the web browser that parses every line of code at runtime. Developers need to review all animations intended for deployment on an actual device to ensure optimal performance. Therefore, a CH5 project on these devices will not match the performance of the project on a developer workstation. Crestron HTML5 runs on certain low-powered embedded devices.
