If you’ve been keeping tabs on various Web design blogs, you’ve probably noticed that the
:after pseudo-elements have been getting quite a bit of attention in the front-end development scene — and for good reason. In particular, the experiments of one blogger — namely, London-based developer Nicolas Gallagher — have given pseudo-elements quite a bit of exposure of late.
To complement this exposure (and take advantage of a growing trend), I’ve put together what I hope is a fairly comprehensive run-down of pseudo-elements. This article is aimed primarily at those of you who have seen some of the cool things done with pseudo-elements but want to know what this CSS technique is all about before trying it yourself.
Perhaps one of the most talked about websites in the last 12 months has been Nike Better World. It's been featured in countless Web design galleries, and it still stands as an example of what a great idea and some clever design and development techniques can produce.
In this article, we’ll talk to the team behind Nike Better World to find out how the website was made. We'll look at exactly how it was put together, and then use similar techniques to create our own parallax scrolling website. Finally, we'll look at other websites that employ this technique to hopefully inspire you to build on these ideas and create your own variation.
Over my programming career, I have made a lot of mistakes in several different languages. In fact, if I write 10 or more lines of code and it works the first time, I’ll get a bit suspicious and test it more rigorously than usual. I would expect to find a syntax error or a bad array reference or a misspelled variable or something.
I like to classify these mistakes into three broad groups: cock-ups (or screw-ups in American English), errors and oversights. A cock-up is when you stare blankly at the screen and whisper “Oops”: things like deleting a database or website, or overwriting three-days worth of work, or accidentally emailing 20,000 people. Errors cover everything, from simple syntax errors like forgetting a
} to fatal errors and computational errors.
Joomla is a popular open-source content management system with a lot of possibilities. One of the strengths of Joomla is the vast number of extensions and templates available, both free and commercial. You can download and install a template in a few simple steps, although some templates are included in the Joomla installation package, and most users start with one of those. This article takes you through one of the default Joomla 1.5 templates and shows you how to modify it for your website.
Joomla 1.6, which was released earlier this year, has a different way of handling templates. For instance, it introduced the concept of template styles. However, many users are still on Joomla 1.5. Thus, the information in this post will be valid to many Joomla users. Also, the techniques used in this post can be applied to Joomla 1.6 and later versions even if the template structure is somewhat different.
For designers, Android is the elephant in the room when it comes to app design. As much as designers would like to think it’s an iOS world in which all anyones cares about are iPhones, iPads and the App Store, nobody can ignore that Android currently has the majority of smartphone market share and that it is being used on everything from tablets to e-readers. In short, the Google Android platform is quickly becoming ubiquitous, and brands are starting to notice.
But let’s face it. Android’s multiple devices and form factors make it feel like designing for it is an uphill battle. And its cryptic documentation is hardly a starting point for designing and producing great apps. Surf the Web for resources on Android design and you’ll find little there to guide you.
Let’s assume you have built a nice little Ruby on Rails application on your local development machine. Now it’s time for the application to go live. But where should you host this application? You know that you (or your client) do not have much money to spend, and so you look at the options. You notice right away that managed hosting of applications tends to be relatively expensive.
Heroku is a good option, but it doesn’t give you storage space, and more importantly, it lacks full control. Luckily, you have a suitable alternative: a VPS. This tutorial will help you get through the steps required to set up an Ubuntu VPS that is capable of hosting (multiple) Ruby on Rails applications. This tutorial builds on part 1. We recommend that you follow that part first and use the same Ubuntu local development machine that you set up there to walk through this part.
Since Rails 3 was released, developers have been writing Rails engines in a new clean style that can be packaged as RubyGems. A Rails engine is a prepackaged application that is able to be run or mounted within another Rails application. An engine can have its own models, views, controllers, generators and publicly served static files.
Now, unless you like writing a lot of code, this is great news, because it means you can write an engine once and use it over and over again. Let’s say you build a lot of websites for small businesses. A common requirement for such websites is a page listing all of the employees at a company and some basic information about them. This is a great candidate for a Rails engine gem because the functionality will change very little and can be abstracted to a common set of requirements.
So, you want to develop Ruby on Rails applications? While loads of (introductory) tutorials are available for developing Ruby on Rails applications, there seems to be some uncertainty about setting up a lean and up-to-date local development environment.
This tutorial will guide you through the steps of setting up an Ubuntu local development machine for Ruby on Rails. Part 2 of this tutorial, which will be published here later, will help you through the steps to set up an Ubuntu VPS. For now, knowing that VPS stands for virtual private server is sufficient. It will be able to host your newly developed Ruby on Rails applications. But let’s focus on the local development machine first.
Besides learning how to accomplish these specific tasks, you'll also master a variety of useful CSS and jQuery tricks that you can leverage when creating your own interactive techniques. The solutions presented here are certainly not perfect, so any thoughts, ideas and suggestions on how you would solve these design problems would be very appreciated.
