CSS Techniques

Generating Organic Randomness with Prime Numbers and CSS
At first, you may be wondering why the heck is Alex Walker talking about cicada’s and Web design. Once taking a closer look, a sort of connection between the two evolves and a ‘cicada principle’ is born.
CSS3 3D Hologram
Being inspired by holographic effects that can be achieved with HTML/CSS, Hakim El Hattab has developed his own 3D box which alters perspective depending on device orientation. Note that this requires a webkit browser and has only been tested on iPhone. Also make sure to visit more of Hakim’s CSS/HTML5 experiments.

You’re probably familiar with CSS3 gradients by now, including the closer to the standard Mozilla syntax and the verbose Webkit one. I assume you know how to add multiple color stops, make your gradients angled or create radial gradients. What you might not be aware of, is that CSS3 gradients can be used to create many kinds of commonly needed patterns, including checkered patterns, stripes and more.

Click in the box and start typing on your computer’s keyboard. Cleverly developed by Dustin Cartwright and Dustin Hoffman. You’ve got to respect the amount of time and effort which went into producing this demo.
A couple of nice progress bars created by Chris Coyier that use no images — just CSS3 fancies. In browsers that do not support CSS3, these progress bars will look more simplified.
A tutorial by Chris Coyier which shows us how easy adding a hover state to an element can be. In this case, the hover state is applied to everything but the element actually being hovered over.
With CSS3’s 3D transÂforms it’s possible to creÂate a sphere-like object, albeit with many elements. Paul Hayes shares his version of a 3D CSS sphere (works in the latest Safari and iOS) and provides us with the coding needed.
This demo highlights leading edge CSS3 and HTML5 features that Mozilla Firefox and the open web community push into modern Web browsers.
A tutorial by Dirk Weber that teaches us how to build a 3D packshot in HTML and CSS by applying some CSS 3D-transforms. By adding some Javascript, we can make the object freely rotatable in 3D space. And as we will enhance our Javascript with some touch-interactivity, the packshot will also work nicely in Safari for iOS-platforms like iPhone or iPad.
Nicolas Gallagher shares presents his CSS drop-shadows without any images.
Lea Verou explains how to implement a feature that allows you to increment or decrement a <length> value by pressing the up and down keyboard arrows when the caret is over it.

Roger Johansson shares his thoughts on how to improve centering an element both horizontally and vertically with the display:table alternative.
This article tells you how to create a semantic lean timeline.
These border tricks tricks will help you to display content outside of the content box, over borders, without the use of images, CSS3 gradients or extraneous markup.
Jeffrey Way shows some ways for creating pure CSS text-gradients with a bit of trickery. The key is to use a mix of attribute selectors, webkit-specific properties, and custom HTML attributes.
Divya Manian uses the CSS gradients and shows the results of his work on a project which uses a bunch of circles as a decorative background.
Chris Coyier tries to acchieve “different transitions on mouseenter and mouseleave”, but he isn’t using JavaScript here; we’re talking about CSS :hover state and CSS3 transitions. Hover on, some CSS property animates itself to a new value; hover off, a different CSS property animates.
Lea Verou shows how to style children of elements based on their total number (that is, their total count).
Using CSS3 techÂniques a modal box can be creÂated withÂout JavaScript or images. With a bit of aniÂmaÂtion, tranÂsiÂtion and transÂform, it can be made that litÂtle bit more special. The problem: when you hit the “Back”-button after the modal has popped up and was closed, you’ll see the modal again. But maybe you’ll come with a way to fix it?
The full effect of it (with transition animations) will work in newish WebKit and Opera browsers and Firefox 4 (in real beta as of today). Any other browser will rotate the blocks without transition animation.
Visually hiding content on a web page, usually textual content, is at times a viable technique in web design and development. It can be done for several reasons, most importantly, to improve the experience of a screen reader user. Other reasons include improving readability when CSS cannot be rendered, and improving search engine optimization (SEO). Other exaples about using the Visually Hide Content are shown in this article.
The new features of CSS3 bring with them complexity and new things for us to screw up. This article will help keep us in check as we start using these new features.
Escape sequences are useful because they allow style sheet authors to represent characters that would normally be ignored or interpreted differently by traditional CSS parsing rules. In this article Mert Tol shows how to use these sequences.
To wrap long URLs, strings of text, and other content, you can just apply a carefully crafted chunk of CSS code to any block-level element .
Trevor Davis shows on some examples what you can do with the CSS generated content.
An incredibly useful CSS3 feature when you’re creating columns with floats is box-sizing. It lets you choose which box sizing model to use – whether or not an element’s width and height include padding and border or not. It makes it much easier to define flexible widths where you also need padding and/or borders. A typical example is laying out forms, which can be a real pain when you want flexible widths.
Shi Chuan takes a close look at boilerplates and helps us understand the math we need to tweak the width required for a good resolution to any particular device.
Keith Chu revises Cloud Four’s work and finds a way to alleviate extra HTTP requests, not iPad-specific as well as lack of reusability. In this post, he shares with us his proposed revision to the iPad orientation CSS.
