box-sizing-polyfill

CSS-Filters-Polyfill

This polyfill takes the official CSS filters syntax and translates it to the different equivalent techniques that the browsers know for those effects

CSS-JS-Booster

An easy to use stand-alone PHP-Library (but at the same time also a Wordpress plugin) that combines, optimizes, dataURI-fies, re-splits, compresses and caches your CSS and JS for quicker loading times.

dom-treemap-devtools-extension

A Chrome Devtools extension that helps you explore the distribution of DOM nodes in the document tree.

HTTP-headers

Every call we send to and receive from a web server is accompanied by more or less metadata, also known as the HTTP headers. Usually, those headers stay hidden in the shadows and we barely notice them - and we underestimate their powers. But ignoring them is a mistake! There is a lot happening around them lately. During The last couple of years a lot of new and powerful headers have emerged which, when applied correctly, help us harden our web applications against attacks and make our sites load a lot faster. That's why in this talk, I'm gonna give you the modern take on how to make the web more secure & fast.

CSS-Parser

A nice litte css parser written in php

async-document.write

connection-type-checker

CSS-Prefix-Spawner

Tired of having to repeat all vendor prefixes over and over again just for getting your cross-browser dosis of CSS 3 eyecandy? Bother no more, my friend! Paste your single-vendor CSS or point to the file and we will automatically add the rest.

SASS-Mixins

IMG-2-TABLE

PHP-Script that converts GIF, PNG and JPG images to a TABLE-markup reproducing the image. Good for embedding images non-blockable inside HTML-emails. The lower the color-count the better for resulting code-size!

native-browser-apis

In this talk, I will give you an overview on how far native browser APIs have matured, thus freeing our sites from the grips of jQuery, lodash and other helper libraries. We will look at working more elegantly with arrays and objects in JavaScript, at modern DOM traversal and manipulation possibilities, at event delegation, at native smooth scrolling, look at ways to build carousels without library, we will explore built-in tools for image and font lazy loading, and we will bury DOMContentLoaded forever.

Chroma-Corners

“Chroma Corners” is the name of a new technique to create rounded corners in IE 6 – 8. It uses IE’s chroma-filter as a tool to mask away corner areas, which are created as a graphic and which are filled with a solid color. It is and behaves like standard HTML + CSS as opposed to the newer VML-based approches. It gives you more freeness and needs less photoshopping work than older background image based techniques for rounded corners like “Mountain Top” or “Sliding Doors”.

HTTP-2

20 years have passed since the IETF introduced HTTP/1.1. At the time web pages were still designed with tables and font tags and they had hardly more than four images per page in total. HTTP/1.1 was perfectly suited to this application scenario. For today's projects, however, HTTP/1.1 is a massive bottleneck. To compensate for its conceptual disadvantages, we developed build processes in which we bundle resources via concatenation, inlining or spriting. In addition, we rely on concepts such as domain sharing and cookieless domains. The good news is: HTTP/2 has arrived and puts an end to the disadvantages of its predecessor. And it is supported by all modern browsers. But it's not enough to just flip a switch. We need to rethink and throw established processes and concepts overboard if we are to get the most out of HTTP/2.

imagery-on-the-web

Using images on a website is pretty straightforward, right? It's using an <img> element or a CSS background and then have them display a JPG, PNG or SVG. And that's it. Or is there more to it than that? Well, yes, there is. And it's a truckload full of possibilities.

webtechnologie-gluecksrad

grunt-sass-recursive-import

a-property-to-unlock-the-world

HTML5-WPO-Slides

css-next

After Grid and Flexbox CSS seems to have lost most of its dynamic. The most urgent layout problems seem to be solved and all eyes turn to JavaScript, because that's where all the exciting things seem to happen at the moment. But is CSS really "feature complete"? And does this development standstill really exist? To find that out, we first search for recently implemented CSS properties. Maybe we will find some after all? Then we take a look into the W3C's CSS crystal ball to see if there are some exciting things planned for the future.
