CSS deformation property optimization tips: transform and transition

CSS deformation attribute optimization skills: transform and transition

Introduction:
With the continuous development of Web front-end technology, the application of CSS has become more and more widespread. This includes the implementation of deformation and animation effects on elements. The transform and transition properties of CSS provide a simple and effective way to achieve deformation and transition effects of elements. This article will introduce how to optimize the use of transform and transition attributes, and provide specific code examples.

1. Optimization skills of transform attribute

1. Hardware acceleration
   When realizing the deformation effect of elements, we can use the transform attribute. To improve rendering performance, you can apply hardware acceleration to elements. Set the type of element that is about to be transformed through the CSS will-change attribute, and then trigger hardware acceleration through transform: translateZ(0) or transform: translate3d(0, 0, 0).

Sample code:

.element {
  will-change: transform;
  transform: translateZ(0);
}

2. Restricted transformation effect
   Sometimes we only need a part of the element to be transformed, not the entire element. At this time, you can use the transform-origin property of CSS to specify the starting point of the transformation to achieve the effect of local transformation.

Sample code:

.element {
  transform-origin: top left;
  transform: rotate(45deg);
}

3. Cache transformation
   If multiple elements need to apply the same transformation effect, in order to avoid repeated declarations, the transformation effect can be defined as CSS Classes, and then deformation is achieved by adding or removing classes.

Sample code:

<div class="element transform-effect"></div>
<div class="element transform-effect"></div>

.transform-effect {
  transform: scale(1.5);
}

2. Optimization skills of transition attributes

1. Specify transition attributes
   When multiple attributes change, we Smooth transition effects can be achieved through the transition attribute. To improve performance, you can avoid unnecessary transitions by specifying transition attributes.

Sample code:

.element {
  transition-property: width, height; /* 只对width和height属性进行过渡 */
  transition-duration: 0.3s;
}

2. Transition delay
   Sometimes we need to start the transition effect after a certain period of time after the element state changes. You can use transition-delay properties to achieve.

Sample code:

.element {
  transition-delay: 0.5s; /* 延迟0.5秒后开始过渡效果 */
}

3. Restricted transition effects
   Various transition effects can be achieved by controlling the timing-function attribute of the transition. Using this feature, we can create more complex transition effects.

Sample code:

.element {
  transition-timing-function: cubic-bezier(0.4, 0.0, 0.2, 1); /* 自定义过渡函数 */
}

Conclusion:
By rationally using the transform and transition attributes, we can achieve more efficient element deformation and transition effects. Improve performance and create more exciting animations with techniques such as hardware acceleration, local deformations, cached deformations, and specified transition properties, transition delays, and restricted transition effects.
