现在的网站有的时候为了简洁就是很多的单页滑屏滚动介绍,主要呈现方式有两种,一种是整体的元素一直排列下去,假设有五个需要展示的全屏页面,那么高度是500%,只是展示100%,剩下的可以通过transform进行Y轴定位,也可以通过margin-top实现,第二种就是所有的子元素和页面一样,都显示在当前页面,简单的实现第一种页面。
Html代码:
<div class="container"> <div class="wrapper"> <div class="page page0 active" data-page="0"> 第一页 博客园-FlyElephant </div> <div class="page page1" data-page="1"> 第二页 </div> <div class="page page2" data-page="2"> 第三页 </div> <div class="page page3" data-page="3"> 第四页 </div> </div> </div>
页面样式:
html, body { height: 100%; padding: 0px; margin: 0px; } .container { height: 100%; overflow: hidden; } .wrapper { height: 100%; touch-action: none; transition: all 1000ms ease; } .page { height: 100%; width: 100%; } .page0 { background: #551A8B; } .page1 { background: #FF8247; } .page2 { background: #CD919E; } .page3 { background: #98FB98; }
鼠标滑动控制代码,如果需要获取鼠标的滚轮事件可以直接通过JavaScript,也可以通过query.mousewheel.min.js插件来写,原生态的JS:
/** This is high-level function. * It must react to delta being more/less than zero. */function handle(delta) { if (delta < 0) …; else …;}/** Event handler for mouse wheel event. */function wheel(event){ var delta = 0; if (!event) /* For IE. */ event = window.event; if (event.wheelDelta) { /* IE/Opera. */ delta = event.wheelDelta/120; } else if (event.detail) { /** Mozilla case. */ /** In Mozilla, sign of delta is different than in IE. * Also, delta is multiple of 3. */ delta = -event.detail/3; } /** If delta is nonzero, handle it. * Basically, delta is now positive if wheel was scrolled up, * and negative, if wheel was scrolled down. */ if (delta) handle(delta); /** Prevent default actions caused by mouse wheel. * That might be ugly, but we handle scrolls somehow * anyway, so don't bother here.. */ if (event.preventDefault) event.preventDefault(); event.returnValue = false;}/** Initialization code. * If you use your own event management code, change it as required. */if (window.addEventListener) /** DOMMouseScroll is for mozilla. */ window.addEventListener('DOMMouseScroll', wheel, false);/** IE/Opera. */window.onmousewheel = document.onmousewheel = wheel;
通过JavaScript插件控制控制滚动的代码:
<script type="text/javascript"> $(function() { $('.container').on('mousewheel', function(event) { //mac自然状态向上是-1 //window向上滑动时候是1 向下-1 console.log(event.deltaX, event.deltaY, event.deltaFactor); var currentPage = parseInt($('.active').attr('data-page')); if (event.deltaY > 0) { var prevpage = currentPage - 1; if (prevpage >=0) { $('.page' + prevpage).addClass('active'); $('.page' + currentPage).removeClass('active'); $('.wrapper').css({ 'transform': 'translate(0,' + (prevpage * -100) + '%)' }); } } else { var nextpage = currentPage + 1; if (nextpage < 4) { $('.page' + nextpage).addClass('active'); $('.page' + currentPage).removeClass('active'); $('.wrapper').css({ 'transform': 'translate(0,' + (nextpage * -100) + '%)' }); } } }); }); </script>
关于滚轮的时间的控制,以及不确定页面元素时候的代码没有给出判断,大体思路不变,其他的仅供参考~

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.

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.

HTML is the cornerstone of building web page structure. 1. HTML defines the content structure and semantics, and uses, etc. tags. 2. Provide semantic markers, such as, etc., to improve SEO effect. 3. To realize user interaction through tags, pay attention to form verification. 4. Use advanced elements such as, combined with JavaScript to achieve dynamic effects. 5. Common errors include unclosed labels and unquoted attribute values, and verification tools are required. 6. Optimization strategies include reducing HTTP requests, compressing HTML, using semantic tags, etc.

HTML is a language used to build web pages, defining web page structure and content through tags and attributes. 1) HTML organizes document structure through tags, such as,. 2) The browser parses HTML to build the DOM and renders the web page. 3) New features of HTML5, such as, enhance multimedia functions. 4) Common errors include unclosed labels and unquoted attribute values. 5) Optimization suggestions include using semantic tags and reducing file size.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
