How to achieve page loading effect with CSS3
CSS3 method to achieve page loading effect: first create an HTML sample file; then create a div in the body; finally achieve the page loading effect through animation animation and 2D scaling conversion in transform.
The operating environment of this article: Windows7 system, HTML5&&CSS3 version, Dell G3 computer.
We can make the animation of page loading into different shapes. The case we want to share today is to make the animation into a circular shape to load the page. When using animation, we should pay attention to browser compatibility issues
Detailed explanation of knowledge points
(1) animation: Set animation properties
animation-name: Set the keyframe name that needs to be bound to the selector. This example is bound to load
animation-duration: the time it takes to complete the animation, in seconds or milliseconds.
animation-timing-function: animation speed curve.
animation-delay: The delay before the animation starts.
animation-iteration-count: The number of times the animation should be played.
animation-direction: Whether the animation should be played in reverse in turn.
Example: Set the animation name to load, the time required to complete the animation is 1.4s, start and end at low speed, and play in an infinite loop
animation: load 1.4s infinite ease-in-out;
(2) animation-fill-mode attribute
none: Do not change the default behavior.
forwards: When the animation is completed, keep the last attribute value (defined in the last keyframe).
backwards: During the period of time specified by animation-delay, the start property value (defined in the first keyframe) is applied before the animation is displayed.
both: Both forward and backward fill modes are applied.
(3) transform: scale(x,y) 2D scaling transformation.
