CSS you can get excited about in 2015 CSS is a constantly evolving language, and as the new year begins it’s a great time to take a look at some of the emerging features that we can start to experiment with. In this article I’ll take a look at some newer modules and individual CSS features that are gaining browser support. Not all of these are features you’ll be able to use in production immediately, and some are only available behind experimental flags. However you’ll find plenty of things here that you can begin to play with — even if only during a prototyping stage of development. CSS Selectors level 4 The level 3 selectors specification is well implemented in browsers and brought us useful selectors such as nth-child. The negation pseudo-class :not The negation pseudo-class selector :not appears in level 3 but gets an upgrade in level 4. In level 4 of the specification you can pass in a comma separated list of selectors. The relational pseudo-class :has The matches-any pseudo-class :matches CSS Blend Modes Using mix-blend-mode

HTML5 Boilerplate - A rock-solid default template for HTML5 awesome. Using CSS animations - Web developer guide CSS animations make it possible to animate transitions from one CSS style configuration to another. Animations consist of two components, a style describing the CSS animation and a set of keyframes that indicate the start and end states of the animation's style, as well as possible intermediate waypoints along the way. There are three key advantages to CSS animations over traditional script-driven animation techniques: They're easy to use for simple animations; you can create them without even having to know JavaScript. Configuring the animation To create a CSS animation sequence, you style the element you want to animate with the animation property or its sub-properties. The sub-properties of the animation property are: animation-delay Configures the delay between the time the element is loaded and the beginning of the animation sequence. animation-direction animation-duration Configures the length of time that an animation should take to complete one cycle. animation-iteration-count Examples

HTML5 Video HTML5 enabling script 7 Jan Since HTML5 is getting more attention by way of marking up our new pages, and the only way to get IE to acknowledge the new elements, such as <article>, is to use the HTML5 shiv, I’ve quickly put together a mini script that enables all the new elements. Download html5shiv.js and must be inserted in the head element (this is because IE needs to know about the element before it comes to render them – so it can’t sit in the footer of the page, i.e. below the elements in question). I’ve updated this post to link to Alexander Farkas’s version of the shiv – it’s the very latest and my simple one line script. The one I originally released was (I thought) beautifully small, but didn’t support print styles nor dynamic injection of HTML5 elements. Good thing there are smarter folk than I!

Create offline Web applications on mobile devices with HTML5 Introduction The use of Web development in mobile applications is an increasing trend. However, intermittent network availability is a big obstacle to using Web technology as part of a cloud infrastructure. A traditional Web application simply doesn't work without a network. One solution to this problem is to use two features of the HTML5 Standard (see Resources): Offline Web applicationsClient-side database storage The user can use cloud functions on a mobile device, work offline with a locally deployed application on a local database, and share data with the rest of the cloud when going online again. In this article, learn the technical details for a typical usage scenario. Download the source code for the example application in this article from the Download table below. Overview Figure 1 shows an overview of the major components of the sample application architecture. Figure 1. HTML page The HTML page, the core of the application, has the model role.

HTML5 localStorage() – Part Three « PaperKilledRock.com 11 May You should now have a good idea of how you can use localStorage yourself. However I promised we would create a simple html5 web app and thats what we are going to do. In this post we are going to get our app setup and ready for use. This means it will allow a user to create new entries in their database, display all the entries and allow them to delete a specific entry or remove all entries. In this post we won’t focus on the design of the app but rather making it functional. First we will take what we learned in the last post and write the function that will allow a user to create a new database entry. Snippet CopiedCopy to Clipboard Not much new here that we haven’t already gone over. Now that we have a way for a user to add new items to the app we still need a way to list all the items in the database. Nothing to crazy going on there but lets go over the javascript anyways. Our time tracking web app is finally taking shape. <button type="button" id="clearLog">Clear Log</button>

Slideshow com CSS e HTML - 2bdesign – tutoriais, dicas, inspiração e muito mais A utilização de slideshows na internet é bastante utilizada, dado que permite de uma forma apelativa e interativa apresentar imagens. No entanto, quando estamos atentos ao peso do website na Internet, preocupa-nos a sua utilização. Tecnologias como Flash ou javascript acabam por pecar por isso mesmo. O CSS3 vem permitir isso mesmo: além de variadíssimas outras coisas, criar slideshows com recurso a apenas HTML. Hoje apresentamos um tutorial sobre a criação de um slideshow com recurso a HTML5 e CSS3. Código HTML: <li><a href=”#img01″>1</a></li> <li><a href=”#img02″>2</a></li> <li><a href=”#img03″>3</a></li> <li><a href=”#img04″>4</a></li> <li><a href=”#img05″>5</a></li> Entre as tags <nav></nav> inserimos os links, que serão depois formatados no css para ganhar a forma de botões, que nos permitirão navegar pelas imagens. Dentro de cada <article></article> com ID igual ao link anchor será inserida uma outra tag <figure></figure> que irá receber a tag <img src/> por cada imagem do slideshow. nav {

HTML Tutorial Surfin’ Safari - Blog Archive » WebKit Does HTML5 Client-side Da Posted by Brady Eidson on Friday, October 19th, 2007 at 4:04 pm The current working spec for the HTML5 standard has a lot of exciting features we would eventually like to implement in WebKit. One feature we felt was exciting enough to tackle now even though the spec is still in flux is client-side database storage. So for the last few weeks andersca, xenon, and I have been cooking up an implementation! The client-side database storage API allows web applications to store structured data locally using a medium many web developers are already familiar with – SQL. The API is asynchronous and uses callback functions to track the results of a database query. database.executeSql("SELECT * FROM test", function(result1) { // do something with the results database.executeSql("DROP TABLE test", function(result2) { // do some more stuff alert("My second database query finished executing!") This initial implementation has some things missing from the spec as well as a few known bugs.

C HTML5 Logo The Movement You're excited about HTML5; we are too. You've not just been enjoying the HTML5-powered web already — you're building it! As adoption and inspiration spreads, the web community will find creative ways to apply HTML5 and related technologies, spark trends, and capture best practices. As momentum builds, we hope you bring this logo along for the ride and paint the world orange. You know that HTML5 badge you've placed oh-so perfectly in your footer? Tweet your HTML5 logo sightings with the hashtag #html5logo Google: HTML5 Rocks presentation In March 1936, an unusual confluence of forces occurred in Santa Clara County. A long cold winter delayed the blossoming of the millions of cherry, apricot, peach, and prune plum trees covering hundreds of square miles of the Valley floor. Then, unlike many years, the rains that followed were light and too early to knock the blossoms from their branches. Instead, by the billions, they all burst open at once. Then came the wind. It roared off the Pacific Ocean, through the nearly uninhabited passes of the Santa Cruz Mountains and then, flattening out, poured down into the great alluvial plains of the Valley. This perfumed blizzard hit Stevens Creek Boulevard, a two-lane road with a streetcar line down its center, that was the main road in the West Valley.

Coding An HTML 5 Layout From Scratch - Smashing Coding HTML5 and CSS3 have just arrived (kinda), and with them a whole new battle for the ‘best markup’ trophy has begun. Truth to be told, all these technologies are mere tools waiting for a skilled developer to work on the right project. As developers we shouldn’t get into pointless discussions of which markup is the best. They all lead to nowhere. Rather, we must get a brand new ideology and modify our coding habits to keep the web accessible. While it is true HTML5 and CSS3 are both a work in progress and is going to stay that way for some time, there’s no reason not to start using it right now. So today we’re going to experiment a little with these new technologies. It’d be a good idea to have a read at some of these articles first: I’ll also assume you know the basics of HTML and CSS. Before we begin… Link There’s a couple of things you have to bear in mind before adventuring on the new markup boat. A word on Progressive Enhancement and Graceful Degradation Link 1. 2. <!
