With the arrival of IE9, Microsoft has signalled its intent to work more with standards-based technologies. With IE still the single most popular browser and in many ways the browser for the uninitiated, this is hopefully the long awaited start of us Web craftsmen embracing the idea of using CSS3 as freely as we do CSS 2.1.
However, with IE9 not being supported on versions of Windows before Vista and a lot of businesses still running XP and reluctant (or unable) to upgrade, it might take a while until a vast majority of our users will see the new technologies put to practice. While plenty of people out there are using CSS3, many aren’t so keen or don’t know where to start. This article will first look at the ideas behind CSS3, and then consider some good working practices for older browsers and some new common issues.Read more...
CSS3 is a wonderful thing, but it’s easy to be bamboozled by the transforms and animations (many of which are vendor-specific) and forget about the nuts-and-bolts selectors that have also been added to the specification. A number of powerful new pseudo-selectors (16 are listed in the latest W3C spec) enable us to select elements based on a range of new criteria.
Before we look at these new CSS3 pseudo-classes, let’s briefly delve into the dusty past of the Web and chart the journey of these often misunderstood selectors.Read more...
Plugins are a major part of why WordPress powers millions of blogs and websites around the world. The ability to extend WordPress to meet just about any need is a powerful motivator for choosing WordPress over other alternatives. Having written several plugins myself, I've come to learn many (but certainly not all) of the ins-and-outs of WordPress plugin development, and this article is a culmination of the things I think every WordPress plugin developer should know. Oh, and keep in mind everything you see here is compatible with WordPress 3.0+.
The first thing you should do when developing a WordPress plugin is to enable debugging, and I suggest leaving it on the entire time you're writing plugin code. When things go wrong, WordPress raises warnings and error messages, but if you can’t see them then they might as well have not been raised at all. Enabling debugging also turns on WordPress notices, which is important because that's how you'll know if you're using any deprecated functions.Read more...
CAPTCHAs, or Completely Automated Public Turing Tests to Tell Computers and Humans Apart, exist to ensure that user input has not been generated by a computer. These peculiar puzzles are commonly used on the web to protect registration and comment forms from spam. To be honest, I have mixed feelings about CAPTCHAs. They have annoyed me on many occasions, but I’ve also implemented them as quick fixes on websites.
This article follows the search for the perfect solution to the problem of increasing amounts of human-generated spam. We’ll look at how and why CAPTCHAs are used and their effect on usability in order to answer key questions: what is the perfect CAPTCHA, and are they even desirable?Read more...
When the CSS1 specification was drafted in the mid to late 90s, it introduced
!important declarations that would help developers and users easily override normal specificity when making changes to their stylesheets. For the most part,
!important declarations have remained the same, with only one change in CSS2.1 and nothing new added or altered in the CSS3 spec in connection with this unique declaration. [Links checked February/15/2017]
Let's take a look at what exactly these kinds of declarations are all about, and when, if ever, you should use them. But before we get into
!important declarations and how exactly they work, let's give this discussion a bit of context. In the past, Smashing Magazine has covered CSS specificity in-depth, so please take a look at that article if you want a detailed discussion on the CSS cascade and how specificity ties in.
All of which means that, unless you have some odd grudge against jQuery, those days are gone — you can actually get stuff done now. A script to find all links of a certain CSS class in a document and bind an event to them now requires one line of code, not 10. To power this, jQuery brings to the party its own API, featuring a host of functions, methods and syntactical peculiarities. Some are confused or appear similar to each other but actually differ in some way. This article clears up some of these confusions.

It is arguable that there is no goal in web design more satisfying than getting a beautiful and intuitive design to look exactly the same in every currently-used browser. Unfortunately, that goal is generally agreed to be almost impossible to attain. Some have even gone on record as stating that perfect, cross-browser compatibility is not necessary. [Links checked & repaired March/06/2017]
While I agree that creating a consistent experience for every user in every browser (putting aside mobile platforms for the moment) is never going to happen for every project, I believe a near-exact cross-browser experience is attainable in many cases. As developers, our goal should not just be to get it working in every browser; our goal should be to get it working in every browser with a minimal amount of code, allowing future website maintenance to run smoothly.
In this article, I'll be describing what I believe are some of the most important CSS principles and tips that can help both new and experienced front-end developers achieve as close to a consistent cross-browser experience as possible, with as little CSS code as possible.Read more...
In Modern CSS Layouts, Part 1: The Essential Characteristics, you learned that modern, CSS-based web sites should be progressively enhanced, adaptive to diverse users, modular, efficient and typographically rich. Now that you know what characterizes a modern CSS web site, how do you build one? Here are dozens of essential techniques and tools to learn and use to achieve the characteristics of today's most successful CSS-based web pages.
Just as in the previous article, we're not going to be talking about design trends and styles; these styles are always changing. Instead, we're focusing on the specific techniques that you need to know to create modern CSS-based web pages of any style. For each technique or tool, we'll indicate which of the five characteristics it helps meet. To keep this shorter than an encyclopedia, we'll also just cover the basics of each technique, then point you to some useful, hand-picked resources to learn the full details.Read more...
CSS’ barrier to entry is extremely low, mainly due to the nature of its syntax. Being clear and easy to understand, the syntax makes sense even to the inexperienced Web designer. It's so simple, in fact, that you could style a simple CSS-based website within a few hours of learning it. [Links checked March/06/2017]
But this apparent simplicity is deceitful. If after a few hours of work, your perfectly crafted website looks great in Safari, all hell might break loose if you haven’t taken the necessary measures to make it work in Internet Explorer. In a panic, you add hacks and filters where only a few tweaks or a different approach might do. Knowing how to deal with these issues comes with experience, with trial and error and with failing massively and then learning the correct way.
Understanding a few often overlooked concepts is also important. The concepts may be hard to grasp and look boring at first, but understanding them and knowing how to take advantage of them is important.Read more...
In an online world now dominated by CSS layouts, CSS-styled HTML lists have become invaluable tools in a CSS developer's toolbox, due to the HTML lists versatile and graphically flexible nature. All this despite some of the obvious browser inconsistencies that can affect the styling of the different types of lists available in HTML coding.
If you're new to CSS, this article should provide a good overview of the different types of lists available, as well as some of the browser quirks that occur in relation to HTML lists, with some helpful advice that should prevent those quirks from becoming major road blocks to good design.
In addition, we'll look at a showcase of various uses, techniques, and tutorials that utilize HTML lists. All of this should put strong emphasis on the importance of using lists in modern web design, reminding even experienced coders how HTML lists can improve the flexibility and maintainability of a website.Read more...
Buttons, whatever their purpose, are important design elements. They could be the end point of a Web form or a call to action. Designers have many reasons to style buttons, including to make them more attractive and to enhance usability. One of the most important reasons, though, is that standard buttons can easily be missed by users because they often look similar to elements in their operating system. Here, we present you several techniques and tutorials to help you learn how to style buttons using CSS. We'll also address usability.
Before we explain how to style buttons, let's clear up a common misconception: buttons are not links. The main purpose of a link is to navigate between pages and views, whereas buttons allow you to perform an action (such as submit a form).Read more...
