How to Customize Browser Scrollbars Using CSS
We`re all using web browsers to navigate on internet. Most of you(to be more specific, 65% according to my analytics) are using Chrome and Safari to navigate through this website. These 2 browsers have something in common: they are both built on the WebKit platform, or in other words, they are WebKit browsers. Did you know that you can customize the way a scrollbar looks? Customizing scrollbars is easy, being based on a pure CSS solution, but there`s a glitch: custom scrollbars works only for WebKit browsers. Let`s write some code: As you noticed already, each element has the custom prefix ::-webkit-.
transform-function
Syntax The <transform-function> data type is specified using one of the transformation functions listed below. Each function applies a geometric operation in either 2D or 3D. Matrix transformation matrix() Describes a homogeneous 2D transformation matrix. matrix3d() Describes a 3D transformation as a 4×4 homogeneous matrix. Perspective perspective() Sets the distance between the user and the z=0 plane. Rotation rotate() Rotates an element around a fixed point on the 2D plane. rotate3d() Rotates an element around a fixed axis in 3D space. rotateX() Rotates an element around the horizontal axis. rotateY() Rotates an element around the vertical axis. rotateZ() Rotates an element around the z-axis. Scaling (resizing) scale() Scales an element up or down on the 2D plane. scale3d() Scales an element up or down in 3D space. scaleX() Scales an element up or down horizontally. scaleY() Scales an element up or down vertically. scaleZ() Scales an element up or down along the z-axis. Skewing (distortion) skew() skewX() skewY()
RESTful Web services: The basics
The basics REST defines a set of architectural principles by which you can design Web services that focus on a system's resources, including how resource states are addressed and transferred over HTTP by a wide range of clients written in different languages. If measured by the number of Web services that use it, REST has emerged in the last few years alone as a predominant Web service design model. REST didn't attract this much attention when it was first introduced in 2000 by Roy Fielding at the University of California, Irvine, in his academic dissertation, "Architectural Styles and the Design of Network-based Software Architectures," which analyzes a set of software architecture principles that use the Web as a platform for distributed computing (see Resources for a link to this dissertation). This article suggests that in its purest form today, when it's attracting this much attention, a concrete implementation of a REST Web service follows four basic design principles: Back to top
Performance & Organization - An Advanced Guide to HTML & CSS
Having the ability to write HTML and CSS with a solid understanding is a great expertise to have. As a website’s code base and traffic grows, a new skill set comes into play, one that is extremely important to both development time and user experience. Knowing the fundamentals of website performance and organization can go a long way. The organization and architecture of a code base can greatly affect not only the speed of development, but also the speed at which pages render. Both of which can be sizeable concerns not only for developers but also users. Additionally, taking a few small steps to improve the performance of a website can pay off in dividends. Strategy & Structure The first part to improving a website’s performance and organization revolves around identifying a good strategy and structure for developing the code base. Style Architecture The architecture outlined above includes three directories, all with individual groups of styles. Object Oriented CSS Choosing a Methodology
CSS drop-shadows without images
Drop-shadows are easy enough to create using pseudo-elements. It’s a nice and robust way to progressively enhance a design. This post is a summary of the technique and some of the possible appearances. Demo: CSS drop-shadows without images Known support: Firefox 3.5+, Chrome 5+, Safari 5+, Opera 10.6+, IE 9+ I’ll be looking mainly at a few details involved in making this effect more robust. After a bit of back-and-forth on Twitter with Simurai, and proposing a couple of additions to Divya’s and Matt’s demos using jsbin, I felt like documenting and explaining the parts that make up this technique. The basic technique There is no need for extra markup, the effect can be applied to a single element. The pseudo-elements need to be positioned and given explicit or implicit dimensions. The next step is to add a CSS3 box-shadow and apply CSS3 transforms. One of the pseudo-elements then needs to be positioned on the other side of the element and rotated in the opposite direction.
Simple example - Node.js, Restify, MongoDb and Mongoose - Backbone.js Tutorials
Before I start, the Backbone.js parts of this tutorial will be using techniques described in "Organizing your application using Modules to construct a simple guestbook. Getting started To easily understand this tutorial you should jump straight into the example code base. Example Codebase Example Demo This tutorial will assist you in saving data(Backbone.js Models) to MongoDb and retrieving a list(Backbone.js Collections) of them back. The technologies This stack is great for rapid prototyping and highly intuitive.

Code a Spinning Circular Menu With CSS
Don’t be a square, break outside your boring box and try on a circle for size. Today we’re going to build a circular navigation menu that spins to different points as the user hovers over an anchor. Along the way we’ll have to overcome several obstacles like how to structure our HTML to be conducive to a remote hover and how to position all of the elements just right so that everything works. Launch Demo – Download Files Step 1: Structural HTML Before we write a single character of HTML, we have to figure out the structure of what it is that we’re building. Basically, each of the rectangles at the top are tied to one of the four little circles inside of the big circle. Every time I try to pull off a remote hover, it takes me a few tries to get the structure just right. Let’s say that we put this structure into place with the idea that we wanted a hover over the anchor to change the color of the paragraph. As it turns out, this simply doesn’t work. So what do we do? Application Take a Look!
