关于@keyframes定义动画的问题_html/css_WEB-ITnose
我想让一个长方形先转30度,再向右走200px距离,然后再转330度,最后走回原位。(代码不考虑兼容性)
运行的时候不是按我想的步骤来的,而是:转30度和向右走同时进行,转330度和往回走同时进行。请问为什么?
怎么写正确的代码完成我的要求?

@keyframes donghua
{
0% {width:120px;height:50px;left:0px; top:0px;}
25% {transform:rotate(30deg);left:0px;}
50% {transform:rotate(30deg);left:200px; top:0px;}
75% {transform:rotate(330deg);left:200px;}
100% {transform:rotate(330deg);left:0px; top:0px;}
}
@keyframes donghua{ 0% {width:120px;height:50px;left:0px; top:0px;} 25% {transform:rotate(30deg);left:0px;} 50% {transform:rotate(30deg);left:200px; top:0px;} 75% {transform:rotate(360deg);left:200px;}100% {transform:rotate(360deg);left:0px; top:0px;}}
@keyframes donghua{ 0% {width:120px;height:50px;left:0px; top:0px;} 25% {transform:rotate(30deg);left:0px;} 50% {transform:rotate(30deg);left:200px; top:0px;} 75% {transform:rotate(360deg);left:200px;}100% {transform:rotate(360deg);left:0px; top:0px;}}
你写的我倒是看明白了,在25%处定义它在left:0px;就可以不右移。 但我还是很奇怪,即便我没有定义left:0px; ,但我也没有让它右移啊,凭什么它就同时右移了?

@keyframes 本来就可以多个属性同时做动画。每个属性的变化都是独立的
你要求的是时间轴在25%到50%时让left从0变化到200;
可你只在 0% 设置left:0px;, 50% 设置left:200px;
25% 中没有设置left属性。就是25%时不对left影响
这样就是时间轴在0%到50%时让left从0变化到200;

HTML is suitable for beginners because it is simple and easy to learn and can quickly see results. 1) The learning curve of HTML is smooth and easy to get started. 2) Just master the basic tags to start creating web pages. 3) High flexibility and can be used in combination with CSS and JavaScript. 4) Rich learning resources and modern tools support the learning process.

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.
