Powerful New CSS- and JavaScript-Techniques (2012 Edition) Advertisement Since our last round-up of useful CSS techniques1, we’ve seen a lot of truly remarkable CSS geekery out there. With CSS3, some of the older techniques now have become obsolete, others have established themselves as standards, and many techniques are still in the “crazy experimentation” stage. Since the release of the previous post, we’ve been collecting, sorting, filtering and preparing a compact overview of powerful new CSS techniques. Please note that many techniques are not only CSS-based, but also use HTML5 and JavaScript.

Keep your CSS selectors short 15 May, 2012 One thing I believe, as a very, very general rule of thumb, is that as sites get bigger, selectors should get shorter. By this I mean that if you want to create extensible and maintainable, flexible and predictable websites, you should really take care to make your CSS selectors as dev-friendly as possible; i.e. short. Keeping CSS selectors short helps with a lot of things: Increases selector efficiencyReduces location dependencyIncreases portabilityReduces chances of selector breakageDecreases specificityCan make code more forgiving This is a very vague list, so I’m going to address each in order. Increases selector efficiency I have written before about CSS selector efficiency. If we ignore actual types of selector (*{} is typically the slowest, depending on how it’s being used, IDs are the fastest followed by classes, descendants are comparably quite slow followed by pseudo-selectors) then in general it is safe to say that shorter selectors are faster. Increases portability

CSS GuidelinesGo! Blog Archive » Cross-Browser Debugging CSS I was helping Laura (a developer who works with me) learn about cross-browser debugging this week, which got me excited to share my process. The first principal is simply: Work with CSS, not against it. CSS has an underlying design and when you work with it, with the natural flow of how CSS is meant to be used, you will find you have a lot less bugs. I learned CSS by reading the W3C specifications, which is why I began coding according to the language’s design, but however you learned it, you can pick up some of the key points involved. The first thing I do is code to a good browser from the start. If there is a discrepancy between these good browsers, chances are you are working against CSS. HTML interpretation – did you forget to close a tag? If you don’t read anything else, read the next two paragraphs The most important thing to keep in mind is that error behavior is not defined in the spec. Display I think of CSS like a choose your own adventure. Positioning Internet Explorer
Hover avec transitions – Réaliser un effet de hover progressif avec les transitions en CSS3 Création d’un hover progressif Un hover progressif ? Je n’ai pas trouvé mieux pour expliquer cet effet pourtant si simple. Plutôt que de gérer un hover ON/OFF, ici le :hover s’applique progressivement, plus précisément, il disparait progressivement. On peut aussi parler de hover temporisé. De plus, l’effet de transition progressive est appliqué sur un dégradé. Puis, sur chaque lien est appliqué un fond de couleur (gris) et lors du :hover, on fait disparaitre ce fond avec les transitions. Obtenez plus d’infos sur l’utilisation des dégradés. Les coins arrondis Dans cette démo, j’utilise également border-radius avec les pseudo-classes :first-child et :last-child pour arrondir le coin supérieur droit du premier <li> et le coin inférieur droit du dernier <li>. Pour la création de la petite flèche, suivez le tutoriel d’utilisation des bordures Astuce : utilisez prefixMyCSS pour ajouter les préfixes propriétaires aux règles CSS3.
