CSS Content CSS has a property called content. It can only be used with the pseudo elements :after and :before. It is written like a pseudo selector (with the colon), but it's called a pseudo element because it's not actually selecting anything that exists on the page but adding something new to the page. This is what it looks like: With this CSS in place, we could have this HTML: <ul><li class="email-address">chriscoyier@gmail.com</li></ul> And the output would be like: • Email address: chriscoyier@gmail.com Maybe that example doesn't get you drooling, but pseduo element content can be quite useful and do cool things. Hey! The first concern might be that of a separation-between-content-and-design purist. I think it's awesome and perfectly suited for CSS. I'm going to publish an article tomorrow with this kind of idea. Using Special Characters If you need to use a special character in the CSS content, it's kinda weird. Here's some random useful ones: Example Trick: Checkmark visited links Using Attributes
Modernizr: the HTML5 and CSS3 Feature-detection Library With the release of version 2.0, the Modernizr JavaScript library continues to gain traction as the solution of choice for advanced browser feature detection. For those of you who haven't been properly introduced, Modernizr uses the latest JavaScript object detection techniques to discover if a feature is available before you use it, thus allowing for graceful degradation or progressive enhancement of your web pages. It is especially useful in assessing emerging web technologies such as CSS3 and HTML5 so that you can fully exploit modern browser capabilities while providing more basic content to older browsers. How It Works The now obsolete traditional method of doing "UA sniffing" was to identify a browser based on its navigator.userAgent property. The obsolete UA sniffing approach: if (document.all) { // IE4 height = document.body.offsetHeight; } else if (document.layers) { // NN4 height = window.innerHeight; } else { // other height = 0; } The more precise feature sniffing method: <!
Social media: The in-house vs. outsourced debate It all started when we, two social media marketers, got into a heated argument over IM. It went something like this: agencyMouse99: I know that I work in an agency, but I cannot believe that companies and brands continue to outsource their social media to us. DigitalDiva: What are you talking about? agencyMouse99: In-house is definitely the way to go. DigitalDiva: Do you mean for maintaining branded profiles, or for short-term campaigns? agencyMouse99: Both! DigitalDiva: You're so wrong. agencyMouse99: Oh yeah? It's a debate that likely rages on behind the closed doors of brand marketers on a regular basis, and it's likely the source of a lot of second guessing, and perhaps even regret from time to time. Issue: AuthenticityagencyMouse99: What is social media if not about authenticity? DigitalDiva: Yes, it is. Issue: TimingagencyMouse99: Conversation on social channels moves fast -- sometimes incredibly fast. DigitalDiva: Let's be honest. Next page >>

13 Truths About Social Media Measurement 1. If you aren’t measuring anything else, social media measurement isn’t the problem. Measurement is a discipline, and it needs to be business-wide. If you’re not measuring anything else, you’ll have a learning curve. 2. The goal is to derive insights that teach you something of value, and then act on them. You probably need to spend three times as much time and effort evaluating and acting on your data than you do collecting and formatting it. 3. Gathering fans on Facebook is an activity. Number of forum posts is an activity. Follow me? 4. Learn how to create measurable objectives and the metrics practically jump out at you. And you don’t need 40 different metrics to underscore a hypothesis or progress toward a goal. 5. Cause means that something you did drove someone to act. Correlation is fuzzier, and where most folks get hung up with measurement. Remember that today, we have any number of points where prospects and customers can be impacted by what we do. 6. 7. 8. 9. 10. 11. 12.
Utiliser CSS3 aujourd'hui : outils et ressources - Alsacréations Bien que les spécifications CSS 3 soient encore en phase de maturation, il devient acquis qu'un certain nombre de ses composantes sont déjà exploitables en production sur les navigateurs actuels, moyennant quelque gymnastique pour notre attachant boulet à tous qu'est Internet Explorer. Le contexte actuel est pour le moins excitant pour nous autres webdesigners, puisque l'on peut enfin s'évader d'une norme CSS2.1 vieille de plus de 10 ans ! Nous nous trouvons dans une période clé, et de grands changements vont bientôt s'opérer dans notre façon de travailler au quotidien. Cependant Internet Explorer modère cet engouement puisque seule sa version 9 commence à supporter ces nouveautés, version encore au stade beta non utilisable par le grand public. De multiples ressources CSS3 pour déjouer les faiblesses d'IE voient le jour presque quotidiennement, notamment par l'ajout de JavaScript. Voyons quelques uns de ces outils en ligne en vogue actuellement : CSS3pie.com CSS3please.com CSS3.info

Foursquare – what is it? « Jojet Just as you thought you we’re getting to grips with Twitter and Facebook something new comes along to upturn the apple cart…typical eh?! “Foursquare“: what is this new upstart?! What is FourSquare? Foursquare (or 4SQ for short) is part of a new breed of mobile applications loosely called “location based services“…and the location bit is key here. Foursquare is an application which runs on mobiles phones such as iPhones, Blackberries (as well as less advanced ones) which allows you to “check in” to venues (i.e. shops!) – think airport check ins but much, much simpler! If you check in often enough then you can become the “mayor” of the venue. But what’s the point of collecting badges and being a ‘mayor‘? Good question!! If the whole purpose of Foursquare was only about collecting badges or being some sort of virtual mayor then there would be little appeal to me and little long term value; but, if you dig a little deeper, more is revealed! Rewarding Behaviour What’s in it for the venues?
Quick Tip: Understanding CSS3 Gradients Creating an image only for the purpose of displaying a gradient is inflexible, and is quickly becoming a bad practice. Unfortunately, at the time of this writing, they very well might still be required, but hopefully not for much longer. Thanks to Firefox and Safari/Chrome, we can now create powerful gradients with minimal effort. In this video quick tip, we'll examine some of the differences in syntax when working with the -moz and -webkit vendor prefixes. While Mozilla and Webkit generally adopt the same syntax for CSS3 properties, they unfortunately don't quite agree when it comes to gradients. Don't worry if your eyes gloss over at that syntax; mine did too! What type of gradient? Firefox, which implemented gradient support with version 3.6, prefers a slightly different syntax. Note how we've placed the type of gradient, linear, within the vendor extension. What if you don't need a 100% gradient from one color to another? Note the subtle off-white to white gradient at the top.
