Although CSS isn’t that difficult, useful CSS techniques are not easy to find. Sometimes finding a cross-browser solution might take time, but you don’t have to reinvent the wheel every single time. Other designers may have had the same problem in the past and thus the main goal of this round-up is to share with you a goldmine of new techniques which you will hopefully find very useful and valuable. We also hope that these tutorials and articles will help you solve common design problems and find new ways of approaching tricky CSS issues.
The main goal of the article is to present powerful new CSS techniques, encourage experimentation in the design community and push CSS forward. Please notice that we feature both experimental demos and practical techniques in this article. Next week we will present even more useful new tools and resources for front-end developers. We sincerely appreciate the efforts of the design community — thank you, guys!
This is a remarkable example of what can be done using CSS3 3D transformations. The interesting stuff is the possibility of manipulate the transformation matrix of any element of the DOM, In this case we get the matrix given only the four end points of the element. Don’t forget to click on the items, too. Who thought a couple of years ago that something like that would be possible with only CSS?

Angled Content Mask with CSS
This article explains how to create angled CSS content “masks”. The idea is pretty simple and uses CSS transform property (rotation, to be more precise).
Rotating Feature Boxes
All the animation here are CSS3 transitions. JavaScript only watches for the clicks and applies and removes classes as needed. So when you click on a block, that block’s class’ is adjusted. The new classes have different size and position values. Because the block has transition CSS applied, those new sizes and postion values are animated as well.

You just make a block level element with zero width and height, a colored border on one side, and transparent borders on the two adjacent sides. Useful for little arrow sticking out from speech bubbles, navigation pointers, and more.
Responsive Images: Experimenting with Context-Aware Image Sizing
Since Ethan Marcotte coined the term, responsive Web design has gained a lot of attention in the Web design community, mainly due to its remarkable potential for flexible layouts that respond to the browser’s viewport for the best user experience. The main problem with such designs, however, is figuring out how to serve small images to mobile devices and tablets and large ones to desktop displays. The goal of this technique is to deliver optimized, contextual image sizes for responsive layouts that utilize dramatically different image sizes at different resolutions.

This tutorial explains how to take an ordinary
select element, and replace it with a better looking version, while keeping all the functionality intact. It uses CSS3 multiple background and a transparent PNG image as a sprite. Currently, multiple backgrounds are supported by Firefox, Safari, Chrome and Opera. For Internet Explorer and older versions of the first browsers, a fallback is defined, which is basically just a regular version of the background. When parsing the CSS document, browsers that do not understand multiple background will just ignore the rule and use the plain one.This tutorial shows how to create a 3D slideshow using only HTML and CSS.

Useful for little arrow sticking out from speech bubbles, navigation pointers, and more.

The main problem with such designs, however, is figuring out how to serve small images to mobile devices and tablets and large ones to desktop displays. The goal of this technique is to deliver optimized, contextual image sizes for responsive layouts that utilize dramatically different image sizes at different resolutions.
Harry Roberts presents a simple technique that uses an image and CSS to create clean ribbons. This technique creates a white
with a pink background, pulls the
out of the content area with a negative margin and then places the image absolutely left-bottom of the :before pseudo-element.
Create a centred horizontal navigation
Centring block level elements is easy, just define a width and set margin: 0 auto;, but what if you don’t know that fixed width? You could use text-align: center;, but that won't work on 100%-width block-level elements either. However, there is a way to have a centred horizontal navigation without knowing an explicit width, and without adding CSS.
Keep Margins Out of Link Lists
When building a menu or other list of links, it's generally a good practice to use display: block; or display: inline-block; so that you can increase the size of the link target. The simple truth: bigger link targets are easier for people to click and lead to better user experience. Make sure list items don't have padding, but links do and don't use margins, so there are no un-clickable gaps.
Pure CSS3 Post Tags
This is a rather simple pure CSS trick you can use to style your blog post tags, usually placed at the bottom of the posts. See also Image-Free Tag Shape.
Styling children based on their number, with CSS3
Lea Verou presents an interesting technique for styling children based on their number. It is based on the relationship between :nth-child and :nth-last-child. With the technique, the number of total rules is still O(N), but the number of selectors in every rule becomes just 2, making this trick practical for far larger numbers of children.
Wrapping Long URLs and Text Content with CSS
To wrap long URLs, strings of text, and other content, it's enough to apply a carefully crafted chunk of CSS code to any block-level element (e.g., perfect for
tags). Very useful for cases when code snippets need to be presented in a blog post with a fixed content width.
Pure CSS(3) accordion
An
interesting accordion technique that uses nothing but semantic HTML,
CSS and some progressive CSS3. There are also two versions, a horizontal
one and a vertical one.
Target iPhone and iPad with CSS3 Media Queries
A
detailed explanation of how to se CSS3 media queries to apply CSS style
to the portrait and landscape modes in mobile devices such as iPad or
iPhone.
Rein In Fluid Width By Limiting HTML Width
If
you are making a fluid width site but wish to limit the maximum width
it can expand, you can do so easily by literally applying a max-width to the html element. Quick and useful tip.
Inline Boxes with Bottom Alignment
Imagine
that you want to keep a "Submit" button at the bottom of a line box,
aligned with form controls positioned below their label (see below). If
the containing block is not wide enough for the "Submit" button to flow
next to the other controls, that button must be displayed at the
beginning of the next line box with minimal space above it. The article
explains a solution for this problem.
Transparent CSS Sprites
The idea of the technique is to create a transparent sprite allowing the background-color
to show through. If you are familiar with CSS Sprites, you should be
able to grasp this twist relatively easily. Simply, an image with a
transparent “knocked-out” transparent center is placed over a background
colour. Changing the background colour changes the appearance of the
element.
Jump links and viewport positioning
"Using
within-page links presses the jumped-to content right at the very top
of the viewport. This can be a problem when using a fixed header. With a
bit of hackery, there are some CSS methods to insert space between the
top of the viewport and the target element within a page."
Mimic Equal Columns with CSS3 Gradients
"What
happens when your main content area needs two specific background
colors: one for the primary content, and another for the sidebar? If
you’ve ever tried applying the background to each container itself,
you’ll no doubt have realized that your layout quickly becomes
fragmented as soon as the primary content section exceeds the height of
the sidebar. Generally, the solution is to set a background image on the
parent element, and set it to repeat vertically. However, if we get
clever with CSS3 gradients, we can achieve the same effect with zero
images." A nice piece by Jeffrey Way.
Double Click in CSS
There has been some interesting talk about how we essentially lose the
:hover pseudo class in CSS as well as mouseenter, mouseleave, and
mousemove in JavaScript. Now, here is the idea: can we somehow pull off a
double click with pure CSS? Yes, we can, if the input covers link,
buries on focus, which triggers hover on link keeping it on top. Work on
WebKit (including Mobile) and Firefox. So we've basically created a
"light" alternative to hover for the sequence tap → change state /
activate link → tap again to visit link.
Center Multiple DIVs with CSS
At some point, you may have a situation where you want to center multiple elements (maybe «div»
elements, or other block elements) on a single line in a fixed-width
area. Centering a single element in a fixed area is easy. Just add margin: auto
and a fixed width to the element you want to center, and the margins
will force the element to center. You can achieve something similar by
taking advantage of CSS’s flexibity with “recasting” elements.
Clearing Floats with Overflow
One
of the common problems we face when coding with float-based layouts is
that the wrapper container doesn't expand to the height of the child
floating elements. The typical solution to fix this is by adding an
element with clear float after the floating elements or adding a
clearfix to the wrapper. But you can also use the overflow property to fix this problem. It's not a new trick, but still very useful.
Different Transitions for Hover On / Hover Off
The
idea of this technique is to solve an interesting problem: what about
using different transition for hover on and off? In the example, when
you hover over, the :hover transition overrides the
transition set in the regular state, and that property animates. When
you hover off, the transition from the regular state takes over and that
property animates. Useful.
Stretch a Box to its Parent's Bounds
A
powerful feature that enables absolute positioning of stretching a box.
The most popular use is having a box positioned in either top or bottom and right or left coordinates.
Equal Height Column Layouts with Borders and Negative Margins in CSS
This article demonstrates different construct techniques and brushes up on a few concepts you might have missed.
Using CSS Text-Shadow to Create Cool Text Effects
The
CSS3 text-shadow property has been around for some time now and is
commonly used to recreate Photoshop's Drop Shadow type shading to add
subtle shadows which help add depth, dimension and to lift an element
from the page. A demo is available if you'd like to see what it looks
like before you give it a try yourself.
Fluid Width Equal Height Columns
Equal
height columns have been a need of web designers forever. If all the
columns share the same background, equal height is irrelevant because
you can set that background on a parent element.
CSS Box-Shadow:Inset
It's
always nice to be able to add a vignetting effect to photos
sans-Photoshop, but the way browsers interpret box-shadow:inset is to
throw the shadow behind the image, rendering it invisible. While this
seems pretty useless, it does make sense when you consider other kinds
of content.
Flexible Navigation
An interesting technique for a navigation that uses only CSS transforms and transitions and no JavaScript.
Circle Zoom
A
very nice hover effect: the Twitter icon has a circle as a background
and the circle increases its radius when the users hovers the mouse over
it.
Last Click
CSS3 Memory
A game of memory in which you will have to find three matching cards (as a tribute to the CSS transitions).
