REM to PX Browser Function with Sass
Performance is a key skill for front-end developers today. New CSS3 and HTML5 features help improve our apps but sometimes these features aren't well supported. This is where Graceful Degradation comes in. You want to leverage the extended features of new browsers but can't afford to ignore support for legacy browsers. I recently started a new project where IE8 support was required. Due to cascade
A Visual Guide to Sass & Compass Color Functions - Jackie Balzer
Sass and Compass provide a number of useful functions you can use to alter and manipulate colors with ease. Most color functions operate on a single color, but some can be used to combine two colors in different ways. Our "base color" and "alternate color" will be used throughout the examples. You can click on the swatch for either of those two colors to change their values and see how the calcula
Refactoring DOM Heavy JS - Jack Franklin
June 3, 2013Refactoring DOM Heavy JSOne of the things I've been getting more into recently is refactoring. It's something that is heavily talked about in the Ruby world, but seems to be a bit less so in the JS world. In this post what I've done is write some of my own (crappy) JavaScript for some simple JS tabs, using bad habits and code smells. I'll then look at how, if I was new to this code, I
smelnikov/FChain · GitHub
FChain is a library that can be used as a base to construct slideshows, presentations , image galleries or just used to run a predetermined number of functions in order. At it's core it is simply an array-like object of functions, which can be traversed through or automatically executed based on a timer. Examples var setColor = function(color) { return function() { document.body.style.backgroundCo
Francisco Soto — Fun with Javascript and function tracing
Fun with Javascript and function tracing May 18, 2013 The problem It was a normal day at my job, my team mates were putting the finishing touches and bug fixes into our latest features, due to be released during Finovate Spring. I wasn’t part of that project but found myself free of my own tasks and decided to jump in to help. And so a bug report came to me. The bug was simple, when adding some ex
Doctrina - JavaScript: Function Invocation Patterns
JavaScript has been described as a Functional Oriented Language (this as opposed to Object Oriented Language). The reason is because functions in JavaScript do more than just separate logic into execution units, functions are first class citizens that also provide scopeL1 and the ability to create objects. Having such a heavy reliance upon functions is both a blessing and a curse: It's a blessing
SASS px to em and em to px - Some code from jimmynotjim - Forrst
// Convert px to em @function pxtoem($target, $context){ @return ($target/$context)+0em; } // Convert em to px @function emtopx($target, $context){ @return ($target*$context)+0px; } Included in my SASS Button mix-in (the previous post) was a custom function I wrote that easily converted pixels to ems (inspired by Andrew F's converter for LESS). I realized there may be times the conversion needed
sassの抑えておきたいfunctionの使い方 « NAVER Engineers' Blog
こんにちは。 年末の予定はぶっ通しでスカイリムにつぎ込むことが決定したUIT富田です。 今回は、Less & Sass Advent calendar 2011の6日目として、 sassのfunctionについて解説します。 すっぽりハマった四則演算の落とし穴 sassは値の四則演算をサポートしており、10進数だけでなく、16進数の値であってもよしなに計算してくれます。 color: #a3a4a5 + #111111; ↓ color: #b4b5b6; 16進数と10進数でもエラーにならず計算してくれます。（普通あまりやらないとは思いますが） color1: #000000 + 1; color2: #000000 + 15; ↓ color1: #010101; color2: #0f0f0f; この16進数の計算は、結果が#fffffを上回った場合、上回った分は切り捨てて、す

Pushing Files to the Browser Using Delivery.js, Socket.IO and Node.js - Liam Kaufman
Recently I’ve been working with both the HTML 5 File API and Socket.IO and it occured to me that those technologies could be used to send, and push, files between the client and server. Immediately I set about making delivery.js, a simple node module that makes it extremely easy to send and push files between the client and the server via Socket.IO. I should note that this is my first node module,
