Understanding The CSS Property Value Syntax

The World Wide Web Consortium uses a particular syntax to define the possible values that can be used for all CSS properties. You may have seen this syntax in action if you have ever looked at a CSS specification.

Understanding The CSS Property Value Syntax

Let's take a look: <'border-­image-­slice'> = [<number> | <percentage>]{1,4} && fill? This syntax can be hard to understand if you don’t know the various symbols and how they work. However, it is worth taking the time to learn. If you understand how the W3C defines property values, you will be able to understand any of the W3C’s CSS specifications.

Web Image Effects Performance Showdown

As browsers constantly improve their graphical rendering abilities, the ability to truly design within them is becoming more of a reality. A few lines of code can now have quick and dramatic visual impact, and allow for consistency without a lot of effort. And as with most things in web development, there are often many ways to achieve the same effect.

Web Image Effects Performance Showdown

In this post, we'll take a look at one of the most popular image effects, grayscale, and assess both the ease of implementation and performance implications of HTML canvas, SVG, CSS filters, and CSS blend modes. Which one will win?

The Safari Problem With SVG Sprites (Now Fixed)

Update (19.05.2016): The bug was just fixed by Antti Koivisto and has landed in the current update of iOS (9.3.2) and Safari for OS X 9.1.1 (11601.6.17). When a user visits a site using a SVG sprite in a browser with an empty cache, the sprite is cached and will not be loaded multiple times any longer. You'll find more details here (in German), and Sven Wolfermann's results before and after the iOS update.

Using external SVG sprite maps to deliver lossless scalable vector images is widely used in responsive web design today and well-supported by tools like svg4everybody.

The Problem With Using SVG-Sprites

At German newspaper Zeit Online, we embraced this technique quite a lot. However, we recently changed this workflow back to completely inlining the SVG into the HTML owing to a bug in Apple's Safari browsers (mobile since iOS 9.3, in Mac OS X since Safari 9.1) – the same way GitHub is doing with its octicons.

Truly Fluid Typography With vh And vw Units

Embracing fluid typography might be easier than you think. It has wide browser support, is simple to implement and can be achieved without losing control over many important aspects of design.

Fluid Typography

Unlike responsive typography, which changes only at set breakpoints, fluid typography resizes smoothly to match any device width. It is an intuitive option for a web in which we have a practically infinite number of screen sizes to support. Yet, for some reason, it is still used far less than responsive techniques.

An Ultimate Guide To CSS Pseudo-Classes And Pseudo-Elements

Hola a todos! (Hello, everyone!) In my early days of web design, I had to learn things the hard way: trial and error.

HTML5 Media Source Extensions: Bringing Production Video To The Web

In the last decade, plugins such as Flash and Silverlight have enabled a rich consumption of video in browsers, powering popular services such as YouTube and Netflix. However, this approach has shifted towards HTML5 over the last few years.

HTML5 Media Source Extensions: Bringing Production Video To The Web

Almost two years ago, the W3C published the final recommendation of the HTML5 spec, which came with a new set of HTML elements and APIs, especially for video. Some of them aim for more semantics in web pages but don’t introduce new features. Others extend the possibilities of the web and enhance the possibilities for developers without the need for plugins such as Adobe Flash, Microsoft Silverlight or Java.
