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

&#8220;Which CSS preprocessor language should I choose?&#8221; is a hot topic lately. I've been asked in person several times and an online debate has been popping up every few days it seems. It's nice that the conversation has largely turned from whether or not preprocessing is a good idea to which one language is best. Let's do this thing. Really short answer: SASS Slightly longer answer: SASS is better on a whole bunch of different fronts, but if you are already happy in LESS, that's cool, at least you are doing yourself a favor by preprocessing.

It exists since the very first steps of CSS and was first released in Dezember 1996 with CSS1. The CSS1 specification is still up, so check it out if you want to. When you write CSS you always use selectors to target

There is a draft for the CSS Hierarchies Module Level 3 which introduces nesting for rules in CSS. This is what preprocessors do. CSS is about to adopt this.

I think all of you know Lea Verou&#8217;s dabblet. dabblet is an interactive playground for quickly testing snippets of CSS and HTML code. It uses -prefix-free, so that you won&#8217;t have to add any prefixes in your CSS code. You can save your work in Github gists, embed it in other websites and share it with others. ~ About dabblet Some time ago I made this tiny Google Chrome App for jsFiddle which is in case just a bookmarklet with a bigger icon. I did this for dabblet, too but extended the app to something more: It displays all your dabblets

At /gebrüderheitz we use Git as a version control system as we think this is the best to work together on a level which is easy to learn and work with. Before we used Git we’ve used SVN but this is by far not as flexible as Git. There are enough posts gathering the difference between Git and SVN so I will not cover any of these. When working in a team it’s important to keep your different stages of development in sync and control somehow: There is a front-end development going on which is in deep connection with the

Some weeks ago I made a pull request for HTML5Boilerplate which should update jQuery to the latest version available on the Google CDN. How ever I copied the old version of minified jQuery because the uncompressed version was available but the minified wasn't. Stupid thing! That's why I created Is Mothereffin' jQuery up? The service checks three major CDNs for the availability of the latest jQuery version. View Is Mothereffin' jQuery up? How to Check if the File is up I had some difficulties to find the right method how to detect if a file is already available with JavaScript.

"Is Mothereffin' jQuery up" is a Tool I created to check if the latest version of jQuery is already up on the Content Delivery Networks.

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…

The CSS3-spec is full of wonderful things one of these is `resize`. What is really useful with resize is the ability to restrict the resizing of elements
