Today we are sad to announce the end of Warhol. We did not see the growth that we hoped for in the past few months and actually getting Warhol's core idea to work proved way harder than we anticipated. We did not see a way forward within our budget of time, money and energy and thus decided to pull the plug. All that development has ceased, backend services are offline, contracts have been canceled. We will endeavor to keep this web page online for as long as possible and probably open-source bits and pieces of Warhol's core functionality.

When I was working in a small agency, years ago, in Germany's warmest city, Freiburg, my boss introduced the team to agile working methods that he had read a book about. We had a whiteboard with some columns on them named To Do, Doing, Done. Some stickies were on these columns. We had a fast-lane which was filled with tasks all the time. I felt I was doing quite some work when fulfilling the tasks and moving a pile of them from one column to the next. Anyway, projects didn't finish on time. The feeling of being productive vanished as soon as we felt we were delivering late. Was there a problem in productivity?

We tend to solve a lot of problems related to the front-end by delegating them to existing programs. We use libraries and tools which we don’t understand completely - our code base grows and grows. But lately this trend seems to change and we slowly re-consider what we can do best: develop front-end code. What can we expect from this new trend and how can we use them in out daily business today?

In the last couple of months I've worked on several projects that needed an overlay with some content on it. Some front-end frameworks as for example Bootstrap refer to them as modals. You can find a lot of implementations that do exactly what I search for but they all have one major drawback: They rely on JavaScript. Yes, sure, everyone has JavaScript enabled these days but why use a technique that you don't necessarily need for a given problem? Also most implementations have drawbacks when it comes to mobile devices and responsive web design in general or accessibility. Apart from

There is a big discussion going on at the moment covering the actual point of how to deal with images and media et al. on mobile-phones and other devices as there are some things that don&#8217;t work as on a desktop computer: Bandwidth Screen size Performance / Velocity The question is how to deliver responsive images on a mobile website. You maybe use something like img { max-width: 100%; height: auto; } in your responsive design to prevent images from being bigger then the screen of a mobile device. In most of the cases this shrinks images in its displayed

Somehow… <time> Disappeared As you might have heard the <time>-element was removed from the HTML5 specification last saturday by Ian "Hixie"; Hickson, the editor of the spec. Hixie decided to remove <time> and replace it by the more general <data>-element. A question that came up: Why got<time> removed and why did nobody stop Hixie? Well: There&lt;/p

There was a hugh discussion about the removal of the HTML5 time-element and replacement by the data from the specification. The W3C HTML WG solved this issue.

Lea Verou publishes some really great stuff. Her latest work is Animatable. A tool to showcase the variety of things you can do with CSS3 animations. And it's awesome. Some weeks ago I had this article about rotating images like I use in the footer of this page. There is an animation in Lea's demos that makes use of the same properties. You will find some nice cutting edge CSS3-techniques in the demos so make sure to check out the source-code on GitHub. You can also contribute and check in a pull request if you want to. Edit: And by

We're doing a project these days where we use an accordion-menu to show some content. I want to share with you how I did this using jQuery and CSS. This is pretty easy and I want to encourage you not to use any plugin or so but to write the code yourself and learn a bit more about how to use CSS and jQuery and save some microseconds on your loading type. The HTML This is kinda straightforward I think. We don't need a wrapper for the accordion-menu. Check it: &lt;section id=&quot;experts&quot; class=&quot;accordion-item&quot;&gt; &lt;h1&gt;&lt;a href=&quot;#experts&quot;&gt;Experts&lt;/a&gt;&lt;/h1&gt; &lt;div class=&quot;content&quot;&gt;&lt;/div&gt; &lt;/section&gt; This is

The CSS3-spec is full of wonderful things. Sometimes things that are not so desperately needed as others but anyway… good to have them. One of these more or less needed properties might be resize. It is part of the CSS3 Basic User Interface Module. What is really useful with resize is the ability to restrict the resizing of textarea for example. But it is possible to resize every element you&#8217;d like to as this demo by Simurai shows. There are four values for resize that are kinda logical: none: no resizing at all horizontal: resizing only horizontal vertical: resizing only…

Some weeks ago Paul Irish published his article about TAFEE (Tiered, Adaptive Front-end Experiences) and shares Paul Boag&#8217;s booklet called &#8220;Where are my rounded corners?&#8221; which tries to describe why it is better to design for the future and modern browsers and not spending too much time trying to get the website&#8217;s design working in older browsers (namely Internet Explorer 7 and 8). The booklet was originally published in Paul Boag&#8217;s blog. Paul describes why he did this this: One of the biggest areas of confusion among our clients is progressive enhancement. They wonder why the beautiful design they signed off

With CSS3 be get some great new functions to use that are now accessible pretty easy. These are not only rounded corners or shadows but also transitions and full animations that let you do things that were only possible with JavaScript some time ago. In the footer of this website I use CSS3 3D-transitions for rotating two images. There is a front- and a back-site for that image. Through animation on click it looks like these images are rotating. I&#8217;m not the first one using this technique. I got inspired by Google+. They are using it for rotation of the

Sven asked me some stuff about the HTML5 Boilerplate Favicon PSD-Template while he was using it for a project. He discovered one problem I was not aware of and I don&#8217;t know how to work around: Android does not use one of the apple-touch-icons as a bookmark or as a shortcut on the home-screen in Android 2.3. I do not know of any other usage of the icons in prior versions of Android. But this article by Rob Flaherty stats that it is working for Android 2.1 and 2.2 with some minor changes. He also set up this demo-page. Feel free

This mothereffin shit is worth a blog-post. Even if it&#8217;s just a short one. At this very moment I&#8217;m celebrating the fact that Internet Explorer 10 now supports text-shadows kinda excessively! Finally! Even Internet Explorer made it! Yayyyy! For more details on this, please go and check out the Internet Explorer 10 Guide for Developers. Microsoft developers explain the usage of text-shadow here. But I guess it should be pretty clear how to use them as other browsers support them like forever. Thanks goes out to Louis Lazaris for his tweet about it. Also @IE tweeted about this. There are also

Microsoft now finally supports CSS text-shadow with Internet Explorer 10 Platform Preview.
