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

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.

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

Les problèmes de flottaison en CSS

The link below provides a pure HTML / CSS solution to this problem. However, it's quite involved and most likely won't work in non-modern browsers:

Demo : Mouseover the blocks below to see the folding animation! use : transition-property: height; transition-duration: 1s; perspective: 1000px; transform-style: preserve-3d; transition-duration: 1s; transform: rotateX(-90deg); transform-origin: top;

TEST case

What to do with these boxes? The six colored boxes (A, a, B, b, C, c) are "draggable", which means you can use your mouse to position them anywhere in the page. The input elements in the colored fieldsets let you set z-index and position values for each one of these six boxes. These fieldsets are color coded, which means a fieldset's background color matches the background color of the box it is supposed to style. Use Firebug to monitor in real time how these elements get styled.

Modèle tabulaire Le design tabulaire à l'aide de CSS (entendons-nous bien, je ne parle évidemment pas des balises HTML table) est voué à un très bel avenir proche, enfin utilisable depuis IE8. Le modèle d'affichage tabulaire permet de réaliser de manière simplissime l'ensemble des cas de figure qui nous compliquent la vie actuellement : Hauteurs de frères identiques, Alignement vertical, Répartition de la hauteur restante, Répartition de la largeur restante, Un menu fluide, Réordonnement des blocs.
