AJAX calls have moved user interaction on the Web a huge step forward: We no longer need to reload the page in response to each user input. Using AJAX, we can call specific procedures on the server and update the page based on the returned values, giving our applications fast interactivity.
What AJAX calls do not cover are updates from the server, which are needed for the modern real-time and collaborative web. This need for updates covers use cases ranging from a couple of users collaboratively editing a document to the notification of potentially millions of readers of a news website that a goal has been scored in a World Cup match. Another messaging pattern, in addition to the response request of AJAX, is needed — one that works at any scale. PubSub (as in “publish and subscribe”) is an established messaging pattern that achieves this.
If you mention printing with CSS to many people who work on the web, print style sheets are the use that comes to mind. We are all well used to creating a style sheet that is called upon when a web document is printed. These style sheets ensure that the print version is legible and that we don’t cause a user to print out huge images.
However, 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, we’ll 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.
The list of charting libraries for the web is already quite long, and you might ask yourself why we would need to make it any longer. Whenever you need to develop an application’s dashboard, embed some usage statistics or simply visualize some data, you will find yourself looking for a charting library that fits your needs.
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.
Today, being a designer is about much more than drawing beautiful interfaces in Photoshop or Fireworks. To properly design a website or application, a UI designer must understand the technology with which their products will be built; therefore, they must have a minimum set of front-end development skills. 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. It might be of no real interest to some of you, but it could add some precious assets to your range of skills.
It’s an exciting time for web APIs, and one to watch out for is the Web Speech API. It enables websites and web apps not only to speak to you, but to listen, too. It’s still early days, but this functionality is set to open a whole array of use cases. I’d say that’s pretty awesome.
In this article, we’ll look at the technology and its proposed usage, as well as some great examples of how it can be used to enhance the user experience.
HTML5 introduced a bunch of new tags, one of which is <details>. This element is a solution for a common UI component: a collapsible block. Almost every framework, including Bootstrap and jQuery UI, has its own plugin for a similar solution, but none conform to the HTML5 specification — probably because most were around long before <details> got specified and, therefore, represent different approaches.
A standard element allows everyone to use the same markup for a particular type of content. That’s why creating a robust polyfill makes sense. Disclaimer: This is quite a technical article, and while I’ve tried to minimize the code snippets, the article still contains quite a few of them. So, be prepared!
So, your designers and developers have created a fantastic front-end design, which the client is delighted with, and your job now is to test it. Your heart begins to sink: Think of all the browsers, all the devices and all of these web pages you’ve got to test, not to mention the iterations and bug fixes. You need a front-end testing plan.
This article shows you what to consider when creating a front-end testing plan and how to test efficiently accross browsers, devices and web pages.
