今天给大家秀一款带有发光动画的HTML5表单,挺酷的,效果图如下:
当表单获取焦点时,表单四周就会呈现出发光动画的效果,并不断地进行颜色渐变;当表单失去焦点时,停止发光。其中颜色渐变的动画只有基于webkit的浏览器才有效果,比如chrome和safari。下面简单贴一下实现这个发光HTML5表单的CSS代码和HTML代码,如果你喜欢可以将它分享给你的朋友。
HTML代码如下:
<div class="rain"> <div class="border start"> <form> <label for="email">Email</label> <input name="email" type="text" placeholder="Email"/> <label for="pass">Password</label> <input name="pass" type="password" placeholder="Password"/> <input type="submit" value="LOG IN"/> </form> </div> </div>
CSS代码如下:
<style> body{ background: #000; color: #DDD; font-family: 'Helvetica', 'Lucida Grande', 'Arial', sans-serif; } .border, .rain{ height: 170px; width: 320px; } /* Layout with mask */ .rain{ padding: 10px 12px 12px 10px; -moz-box-shadow: 10px 10px 10px rgba(0,0,0,1) inset, -9px -9px 8px rgba(0,0,0,1) inset; -webkit-box-shadow: 8px 8px 8px rgba(0,0,0,1) inset, -9px -9px 8px rgba(0,0,0,1) inset; box-shadow: 8px 8px 8px rgba(0,0,0,1) inset, -9px -9px 8px rgba(0,0,0,1) inset; margin: 100px auto; } /* Artifical "border" to clear border to bypass mask */ .border{ padding: 1px; -moz-border-radius: 5px; -webkit-border-radius: 5px; border-radius: 5px; } .border, .rain, .border.start, .rain.start{ background-repeat: repeat-x, repeat-x, repeat-x, repeat-x; background-position: 0 0, 0 0, 0 0, 0 0; /* Blue-ish Green Fallback for Mozilla */ background-image: -moz-linear-gradient(left, #09BA5E 0%, #00C7CE 15%, #3472CF 26%, #00C7CE 48%, #0CCF91 91%, #09BA5E 100%); /* Add "Highlight" Texture to the Animation */ background-image: -webkit-gradient(linear, left top, right top, color-stop(1%,rgba(0,0,0,.3)), color-stop(23%,rgba(0,0,0,.1)), color-stop(40%,rgba(255,231,87,.1)), color-stop(61%,rgba(255,231,87,.2)), color-stop(70%,rgba(255,231,87,.1)), color-stop(80%,rgba(0,0,0,.1)), color-stop(100%,rgba(0,0,0,.25))); /* Starting Color */ background-color: #39f; /* Just do something for IE-suck */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00BA1B', endColorstr='#00BA1B',GradientType=1 ); } /* Non-keyframe fallback animation */ .border.end, .rain.end{ -moz-transition-property: background-position; -moz-transition-duration: 30s; -moz-transition-timing-function: linear; -webkit-transition-property: background-position; -webkit-transition-duration: 30s; -webkit-transition-timing-function: linear; -o-transition-property: background-position; -o-transition-duration: 30s; -o-transition-timing-function: linear; transition-property: background-position; transition-duration: 30s; transition-timing-function: linear; background-position: -5400px 0, -4600px 0, -3800px 0, -3000px 0; } /* Keyfram-licious animation */ @-webkit-keyframes colors { 0% {background-color: #39f;} 15% {background-color: #F246C9;} 30% {background-color: #4453F2;} 45% {background-color: #44F262;} 60% {background-color: #F257D4;} 75% {background-color: #EDF255;} 90% {background-color: #F20006;} 100% {background-color: #39f;} } .border,.rain{ -webkit-animation-direction: normal; -webkit-animation-duration: 20s; -webkit-animation-iteration-count: infinite; -webkit-animation-name: colors; -webkit-animation-timing-function: ease; } /* In-Active State Style */ .border.unfocus{ background: #333 !important; -moz-box-shadow: 0px 0px 15px rgba(255,255,255,.2); -webkit-box-shadow: 0px 0px 15px rgba(255,255,255,.2); box-shadow: 0px 0px 15px rgba(255,255,255,.2); -webkit-animation-name: none; } .rain.unfocus{ background: #000 !important; -webkit-animation-name: none; } /* Regular Form Styles */ form{ background: #212121; -moz-border-radius: 5px; -webkit-border-radius: 5px; border-radius: 5px; height: 100%; width: 100%; background: -moz-radial-gradient(50% 46% 90deg,circle closest-corner, #242424, #090909); background: -webkit-gradient(radial, 50% 50%, 0, 50% 50%, 150, from(#242424), to(#090909)); } form label{ display: block; padding: 10px 10px 5px 15px; font-size: 11px; color: #777; } form input{ display: block; margin: 5px 10px 10px 15px; width: 85%; background: #111; -moz-box-shadow: 0px 0px 4px #000 inset; -webkit-box-shadow: 0px 0px 4px #000 inset; box-shadow: 0px 0px 4px #000 inset; outline: 1px solid #333; border: 1px solid #000; padding: 5px; color: #444; font-size: 16px; } form input:focus{ outline: 1px solid #555; color: #FFF; } input[type="submit"]{ color: #999; padding: 5px 10px; float: right; margin: 40px 0; border: 1px solid #000; font-weight: lighter; -moz-border-radius: 15px; -webkit-border-radius: 15px; border-radius: 15px; background: #45484d; background: -moz-linear-gradient(top, #222 0%, #111 100%); background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#222), color-stop(100%,#111)); filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#22222', endColorstr='#11111',GradientType=0 ); -moz-box-shadow: 0px 1px 1px #000, 0px 1px 0px rgba(255,255,255,.3) inset; -webkit-box-shadow: 0px 1px 1px #000, 0px 1px 0px rgba(255,255,255,.3) inset; box-shadow: 0px 1px 1px #000,0px 1px 0px rgba(255,255,255,.3) inset; text-shadow: 0 1px 1px #000; outline: none; width:80px; } </style>
其中,表单焦点切换需要jquery支持,js代码如下:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script> <script> $(function(){ var $form_inputs = $('form input'); var $rainbow_and_border = $('.rain, .border'); /* Used to provide loping animations in fallback mode */ $form_inputs.bind('focus', function(){ $rainbow_and_border.addClass('end').removeClass('unfocus start'); }); $form_inputs.bind('blur', function(){ $rainbow_and_border.addClass('unfocus start').removeClass('end'); }); $form_inputs.first().delay(800).queue(function() { $(this).focus(); }); }); </script>

HTML5 is a key technology for building modern web pages, providing many new elements and features. 1. HTML5 introduces semantic elements such as, , etc., which enhances web page structure and SEO. 2. Support multimedia elements and embed media without plug-ins. 3. Forms enhance new input types and verification properties, simplifying the verification process. 4. Offer offline and local storage functions to improve web page performance and user experience.

Best practices for H5 code include: 1. Use correct DOCTYPE declarations and character encoding; 2. Use semantic tags; 3. Reduce HTTP requests; 4. Use asynchronous loading; 5. Optimize images. These practices can improve the efficiency, maintainability and user experience of web pages.

Web standards and technologies have evolved from HTML4, CSS2 and simple JavaScript to date and have undergone significant developments. 1) HTML5 introduces APIs such as Canvas and WebStorage, which enhances the complexity and interactivity of web applications. 2) CSS3 adds animation and transition functions to make the page more effective. 3) JavaScript improves development efficiency and code readability through modern syntax of Node.js and ES6, such as arrow functions and classes. These changes have promoted the development of performance optimization and best practices of web applications.

H5 is not just the abbreviation of HTML5, it represents a wider modern web development technology ecosystem: 1. H5 includes HTML5, CSS3, JavaScript and related APIs and technologies; 2. It provides a richer, interactive and smooth user experience, and can run seamlessly on multiple devices; 3. Using the H5 technology stack, you can create responsive web pages and complex interactive functions.

H5 and HTML5 refer to the same thing, namely HTML5. HTML5 is the fifth version of HTML, bringing new features such as semantic tags, multimedia support, canvas and graphics, offline storage and local storage, improving the expressiveness and interactivity of web pages.

The tools and frameworks that need to be mastered in H5 development include Vue.js, React and Webpack. 1.Vue.js is suitable for building user interfaces and supports component development. 2.React optimizes page rendering through virtual DOM, suitable for complex applications. 3.Webpack is used for module packaging and optimize resource loading.
