Flexible CSS cover images I recently included the option to add a large cover image, like the one above, to my posts. The source image is cropped, and below specific maximum dimensions it’s displayed at a predetermined aspect ratio. This post describes the implementation. Demo: Flexible CSS cover images Known support: Chrome, Firefox, Safari, Opera, IE 9+ Features The way that the cover image scales, and changes aspect ratio, is illustrated in the following diagram.

How it works The CSS3 Animation Cheat Sheet is a set of preset, plug-and-play animations for your web projects. All you need to do is add the stylesheet to your website and apply the premade CSS classes to the elements you want animated. The CSS3 Animation Cheat Sheet uses CSS3 @keyframes and works on all the latest browsers (that's IE 10). Using CSS3 @keyframes, you don't have to worry about positioning the element to accomodate the animations - it will animate into place. Add the animation stylesheet to the <head> element of your webpage: Replace css with the name of the directory where the animation stylesheet is. Add an animation class to the element you want animated: Replace slideUp with the desired animation class. For entrance animations, you need to make them invisible by adding the visibility: hidden property to the animated element: visibility: hidden; is used to hide elements before the animation is activated. The values for these animations are relative to the element's size.

WTF, HTML and CSS? 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.

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>.
