As developers and designers it’s our job to make the web welcoming, not overwhelming. The HTML5 Page Visibility API is used effectively in recent projects by Active Theory, such as their work for Under Armor and A Spacecraft For All: click to another tab and you’ll find that the multimedia presentation pauses and the music fades away. This behavior typifies what I like to call the “polite web”: sites that are considerate of users’ attention, bandwidth and abilities.

AJAX calls do not cover updates from the server, which are needed for the modern real-time and collaborative web. PubSub (as in “publish and subscribe”) is an established messaging pattern that achieves this. In this article, Alexander Gödde will look at precisely how PubSub solves the updating problem, and he’ll look at one particular solution (the WAMP protocol) that integrates both the calling of procedures on the server and PubSub into a single API.

Print style sheets is the main thing that comes to mind if you mention printing with CSS. But CSS is also being used to format books, catalogs and brochures — content that may never have been designed to be a web page at all. In this article, Rachel Andrew will take a look at the CSS modules that have been created not for use in web browsers, but to deal with printed and paged media. She’ll explain how the selectors, properties and values that they introduce work. She’ll finish up with a working example that you can use as a starting point for your own experiments.

Chartist was developed for a very particular need: to create simple responsive charts. While other charting libraries do a great job of visualizing data, something is always missing to satisfy this simple yet demanding need. In this article, Gion Kunz will show you how to use Chartist to create your own beautiful responsive charts. You’ll learn some key concepts of Chartist, how to easily extend it and also some advanced features, like responsive configuration overrides and the animation API.

The World Wide Web is not static. Quite the opposite: It’s responsive, fluid, evolving and ever changing.
Web designers need to be familiar with HTML and CSS code and front-end technologies when they conceive a website or application’s interface. In Creative Suite version 6, a CSS Properties panel was added to its toolset — a tool that, if used properly, could help both designers with CSS coding experience and beginners alike. By the end of this article, you should have a better overview of this feature and also know how to use it with CSS Professionalzr, a free extension developed by Matt Stow to further optimize the code generated by the panel.

Ruth John has met some resistance when talking about this API. People either can’t see a need for it with the web, or they would feel uncomfortable talking to their device — both valid views. However, he hopes he will inspire you to at least give it a go and think about it the next time you are building something. Start welcoming speech: It might be just what you’re listening for.

Developing a polyfill is not the easiest challenge. On the other hand, the solution can be used for a relatively long time: standards do not change often and have been discussed at length behind the scenes. Also everyone is using the same language and is connecting with the same APIs which is a great thing. This is quite a technical article, and while Maksim Chemerisuk will try to minimize the code snippets, this article still contains quite a few of them. So, be prepared!

Testing is a critical process that developers should integrate into their workflow to minimize the number of bugs that get caught in the quality assurance phase. In this article, Lawrence Howlett shows you what to consider when creating a front-end testing plan and how to test efficiently accross browsers, devices and web pages. Front-end testing also needs to be budgeted for — with time, resources and money. Whichever tool you pick, stick with it, define a process and put the effort in. The result will be a better website, with significantly fewer bugs.

In the wake of so much “CSS versus JavaScript animation” infighting, a new API specifically for web animation is coming out that might just unite both camps. In 2014, Rachel Nabors had the chance to travel the world to talk about using animation in user interfaces and design. She met and interviewed dozens of people who use and champion both CSS and JavaScript. What you’re about to read is purely observational and as unbiased an account as you will be able to find on the subject of web animation.

In this article, Daniel Sternlicht walks you through the development process of a Chrome extension with modern web tools and libraries. It all begins with an idea. Daniel thought it would be nice to create a Chrome extension that enables you to mark your reading progress in articles so that you can continue reading them later — anywhere. “Markticle” is the name he chose for this extension. He’ll share here the technologies that he used to develop it. After reading this article, you’ll have a ready-to-use “Save for Later”-like Chrome extension.
