Old School Cassette Player with HTML5 Audio Vintage format meets modern web tech: an HTML5 audio player with realistic

A switching title effect where a fixed text element changes with an animation depending on the scroll position.The animations are powered by anime anime.js. We also use imagesLoaded for preloading the images and Charming.js for the handling the letter structure of the titles.

Anime (/ˈæn.ə.meɪ/) is a lightweight JavaScript animation library. It works with any CSS Properties, individual CSS transforms, SVG or any DOM attributes, and JavaScript Objects. Main features Keyframes: Chain multiple animation properties. Timeline: Synchronize multiple instances together. Playback controls: Play, pause, restart, seek animations or timelines. CSS transforms: Animate CSS transforms individually. Function based values: Multiple animated targets can have individual value. SVG Animations: Motion path, line drawing and morphing animations. Easing functions: Use the built in functions or create your own Cubic Bézier curve easing.

element() brings CSS design to a new level, in an easily way. Few ideas that comes to my mind (some that I've already used since the last 4 years): - when you have to deal with duplicated content in advanced effects - live thumbnails of previous/next slides in a slideshow - live zoom over an image, for example in an e-commerce product page - animated background, using CSS Animations or by referencing a video, canvas or SVG - faking backdrop-filter or filter() - watermark with multiples backgrounds from Lea Verou idea - and anything you’re currently thinking of ;) Few things we can note: - prefixed for now in Firefox: -moz-element() - impact on rendering performance when using multiple reference. Not as bad as CSS filters, but still something you have to consider - there’s a CanIUse support page - Issue Chromium - Issue WebKit - No mention from IE Platform Status

As per the jQuery documentation there are following ways to check if a checkbox is checked or not. Lets consider a checkbox for example (Check Working jsfiddle with all examples)

jquery.udraggable.js This plugin provides an API similar to jQueryUI's draggable but with support for unified mouse and touch events. It builds on Michael S. Mikowski's jquery.event.ue unified event plugin.

Here's another updated code: $(document).ready(function() { var $dragging = null; $('body').on("mousedown", "div", function(e) { $(this).attr('unselectable', 'on').addClass('draggable'); var el_w = $('.draggable').outerWidth(), el_h = $('.draggable').outerHeight(); $('body').on("mousemove", function(e) { if ($dragging) { $dragging.offset({ top: e.pageY - el_h / 2, left: e.pageX - el_w / 2 }); } }); $dragging = $(e.target); }).on("mouseup", ".draggable", function(e) { $dragging = null; $(this).removeAttr('unselectable').removeClass('draggable'); }); });​

$ (selector, context).draggable (options) Method The draggable (options) method declares that an HTML element can be moved in the HTML page. The options parameter is an object that specifies the behavior of the elements involved. Syntax $(selector, context).draggable(options); You can provide one or more options at a time using Javascript object. If there are more than one options to be provided then you will separate them using a comma as follows − $(selector, context).draggable({option1: value1, option2: value2..... });

Le but est ici de faire en sorte que l'image de fond que l'on aura placée en CSS conserve son ratio de 16/9 et prenne toute la taille du navigateur, quelle que soit la taille de ce dernier (aka fullscreen). Pratique quand on fait du responsive. Voici le code utilisé : .ratio { background: url("monimage.jpg") no-repeat; background-size: cover; width: 100vw; height: 56.25vw; } Concrètement ce que l'on fait : on donne à l'image la largeur du navigateur grâce à l'unite vw (viewport-width) on lui donne la hauteur à laquelle on a appliqué un ratio 16:9 calculé en faisant 100 * 9 / 16 de la largeur du navigateur

it helps to keep CSS code shorter and smarter. Before diving into practical usage examples, here is a short theory course. This is how MDN describes currentColor: The currentColor keyword represents the calculated value of the element’s color property. It allows to make the color properties inherited by properties or child's element properties that do not inherit it by default.

If you were attentive you should see that the line width: calc( 12.5em ) is the trick here. Why? Let’s see all these widths like in pairs – exactly what we need browsers to do. The first pair is width: 80% (content) and width: 16.666% (sidebar) that does the job in calc() incompatible browsers, which will just ignore calc(). It is the callback (backup). It means that the minority of website visitors will see narrower sidebar on narrower viewports. And that should be perfectly fine for people using older browser versions. The second: width: calc( 100% - 15em ) and width: calc( 12.5em ). This is for newer browser versions which will override the previous width definitions

The recipe for the best user experience: Start with POSH, a simple set of heading/div pairs Add ARIA (role, aria-selected, aria-hidden, aria-labelledby) and tabindex attributes using JavaScript as these would be confusing if there was no behavior attached to the widgets. Use JavaScript to also plug a class on the component according to its type (accordion or tabpanel). Style the widget using the selector inserted by the script, this way containers are not hidden if there is no script support. Use cursor to style the tabs because those behave like buttons (default), not links (pointer). In case the component is displayed as a Tab Panel, style it as an Accordion before its tabs start wrapping (to accomodate user’s font-size) or at narrow widths...... ../..

SVG at a data URI for background images.... just because you can, doesn't mean you should.

Another Use Case: The fill property is one of many reasons SVG is a much more flexible option than typical image files. Let's take icons, as an example. We might have the same set of icons but in two different color schemes. Typical image files (such as JPG, PNG and GIF) would require us to make two versions of each icon — one for each color scheme. SVG, on the other hand, allows us to paint the icons in using the CSS fill property: .icon { fill: black; } .icon-secondary { fill: orange; }

Fortunately, CSS3 introduces the background-size property which allows backgrounds to be stretched or squashed. It’s ideal if you’re creating a template using Responsive Web Design techniques. There are several ways to define sizing dimensions — view the CSS3 background-size demonstration page.

I like to use: - Tiny Scrollbar for the minimalist design - JQuery Custom Content Scroller

(Last updated on Jul 11, 2016 ) Highly customizable custom scrollbar jQuery plugin. Features include: - vertical and/or horizontal scrollbar(s) - adjustable scrolling momentum - mouse-wheel (via jQuery mousewheel plugin) - keyboard and touch support - ready-to-use themes and customization via CSS - RTL direction support - option parameters for full control of scrollbar functionality - methods for triggering actions like scroll-to - update, destroy etc - user-defined callbacks and more.....

A CSS lock is a Responsive Web Design technique that lets you transition smoothly between two values, depending on the current viewport size, rather than jump straight from one value to the other.

Des sortes de “super éléments” ?__Les éléments générant un contexte de formatage block deviennent des sortes de “super éléments” ayant un certain nombre de super responsabilités : ils deviennent entre-autre garants de l’affichage de leurs enfants (qu’ils soient blocks ou inline). Ces super éléments acquièrent également des super pouvoirs très pratiques, et c'est là que ça devient intéressant : __Ils contiennent des flottants __Ils ne s’écoulent pas autour des flottants __Ils ne subissent pas la fusion de marges __Et plein d’autres petites fioritures

Mail::RFC822::Address is a Perl module to validate email addresses according to the RFC 822 grammar. It provides the same functionality as RFC::RFC822::Address, but uses Perl regular expressions rather that the Parse::RecDescent parser. This means that the module is much faster to load as it does not need to compile the grammar on startup. Download Mail::RFC822::Address-0.4.tar.gz or read the documentation. If you want to test the behaviour of the module, an online version is available. The grammar described in RFC 822 is surprisingly complex. Implementing validation with regular expressions somewhat pushes the limits of what it is sensible to do with regular expressions, although Perl copes well. The regular expression below shows the complexity, although its inclusion on this page has caused some confusion:
