The Mystery Of The jQuery Object: A Basic Introduction

Have you ever come across a bit of JavaScript like $(".cta").click(function(){}) and thought, “What the $('#x') is that” If it looks like gibberish to you, then please read on. If you think that snippet of code couldn’t possibly be real, then please browse some jQuery examples. They are full of such constructions.

Responsive Images Done Right: A Guide To <picture> And srcset

On Monday, we published an article on Picturefill 2.0, a perfect polyfill for responsive images. Today's article complements Tim Wright's article and explains exactly how we can use the upcoming <picture> element and srcset, with simple fallbacks for legacy browsers. There is no reason to wait for responsive images; we can actually have them very, very soon. — Ed.

Responsive Images Done Right: A Guide To <picture> And srcset

Images are some of the most important pieces of information on the web, but over the web’s 25-year history, they haven’t been very adaptable at all. Everything about them has been stubbornly fixed: their size, format and crop, all set in stone by a single src.

Picturefill 2.0: Responsive Images And The Perfect Polyfill

Not since the early days of web standards have I seen our community rally around a seemingly small issue: responsive images. Over the last four years (yeah, it’s been about four years), we’ve seen many permutations of images in responsive design.

Responsive Images And The Perfect Polyfill

From the lazier days of setting max-width: 100% (the absolute minimum you should be doing) to more full-featured JavaScript implementations, such as Picturefill and Zurb’s data-interchange method, we’ve spent a lot of time spinning our wheels, banging our heads and screaming at the wall. I’m happy to say that our tireless journey is coming to a close. The W3C and browser makers got the hint.

Frizz-Free JavaScript With ConditionerJS

Setting up JavaScript-based functionality to work across multiple devices can be tricky. When is the right time to load which script? Do your media queries matches tests, your geolocation popups tests and your viewport orientation tests provide the best possible results for your website? ConditionerJS will help you combine all of this contextual information to pinpoint the right moment to load the functionality you need.

Frizz-Free JavaScript With ConditionerJS

Before we jump into the ConditionerJS demo, let’s quickly take a look at the Web and how it’s changing, because it’s this change that drove the development of ConditionerJS in the first place. In the meantime, think of it as a shampoo but also as an orchestra conductor; instead of giving cues to musicians, ConditionerJS tells your JavaScript when to act up and when to tune down a bit.

Rethinking Responsive SVG

If you haven’t seen Joe Harrison’s responsive icons technique yet, you’ll most probably be impressed as much as I was when I first discovered it. In this article, I’d like to explore what we can do with SVG beyond “traditional” scalable vector graphics that are used to replace bitmap PNGs.

Rethinking Responsive SVG

In fact, we can see SVG as an independent module that encapsulates CSS for the customization of views as well as the responsive behavior that also encapsulates JavaScript for the interaction logic. Now, let’s dig a bit deeper into this technique.

A Detailed Introduction To Custom Elements

You’ve probably heard all the noise about Web Components and how they’re going to change Web development forever. If you haven’t, you’ve either been living under a rock, are reading this article by accident, or have a full, busy life which doesn’t leave you time to read about unstable and speculative Web technologies. Well, not me.

A Detailed Introduction To Custom Elements

Web Components are a suite of connected technologies aimed at making elements reusable across the Web. The lion’s share of the conversation has been around Shadow DOM, but probably the most transformative technology of the suite is Custom Elements, a method of defining your own elements, with their own behavior and properties.

Creating A Client-Side Shopping Cart

Session storage is a new feature introduced by the W3C’s “Web Storage” specification. It’s supported in Internet Explorer 8+, Firefox, Chrome, Safari and Opera Desktop (for a complete list, please consult “Can I Use”).

var total = parseInt( sessionStorage.getItem( "total" ) );
var quantity = 2;
var updatedTotal = total * quantity;
sessionStorage.setItem( "total", updatedTotal ); // '240', a string

In this series of articles, we’ll cover in depth a practical implementation of session storage by creating a complete e-commerce shopping cart with the sessionStorage object and jQuery.
