CSS3 can be used to create planetary animations. Here are some of the key points: ** 1. In terms of layout ** 1. ** Interface structure ** - You can create a div-class solarpsy-like solar system container element and set its position to relative. Planet Orbits and Planets were both in Div, and Position was set to Absolute. This kind of container used relative and internal elements to use absolute positioning to achieve a simpler effect, but the disadvantage was that the size was fixed. 2. **3D transformation related settings (if you want to create 3D planetary animation)** - ** 3D space of the parent element is enabled **: When the element is undergoing 3D transformation, the parent element must have 3D space enabled. By setting transform-style: preserve - 3d, the child element will be placed in the three-dimensional space of the parent element (the default value is transform-style: flat, so the child element will be placed in the two-dimensional plane). - ** Set depth of field **: You can specify the distance between the observer and the z = 0 plane through the perspective attribute, which can create a perspective effect on the elements undergoing 3D transformation, making them look more three-dimensional. For example, perspective: 100px, this attribute is set to the parent element of the 3D transformation element. - ** Perspective Point Position **: The perspective point position is the observer's position. It is at the center of the element by default and can be set through the perspective-origin attribute. For example, perspective-origin: 400px 300px means that the relative coordinate axis is offset by 400px to the right and 300px to the bottom. This attribute is also set to the parent element of the 3D transformation element. ** 2. Animation related ** 1. **CSS3 Basic Animation ** - CSS3 animation allows you to create complex animation effects without using javelin. For example, you can use @keyframes to define the keyframes. For example: ```css @keyframes example { from {background - color: red;} to {background - color: yellow;} } .animation { width:100px; height:100px; background - color: red; animation - name: example; animation - duration:4s; } ``` - When creating a planetary animation, you can use a similar method to define the planetary revolution (revolving around the sun), rotation (if needed), and other animation effects. According to the revolution period of the planet, the animation execution time was calculated. 2. **CSS3 transition ** - Transformation could add a visual effect of slowing down the changes of elemental attributes. For example, in a planetary animation, if the attributes of an element (such as size, position, color, and other attributes related to the degree of clarity, such as width, height, background-color, etc.) change, you can use transition-property to set the transition effect, so that the element will present a smooth animation effect when the state changes (such as hovering, clicking, etc., if there is an interaction requirement). However, it should be noted that not all attributes support transition. Attributes such as display, position, z-index, content, and cursors usually do not support transition. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
