Responsive Images: How they Almost Worked and What We Need. It’s our job, as designers and developers, to pick apart even the seemingly most simple tasks to find ways to improve them.

Responsive Images: How they Almost Worked and What We Need

When Ethan Marcotte coined “responsive web design,” he said that a responsive website is made up of three things: a flexible grid, flexible images and media, and media queries. In doing so, he opened up a world of new and exciting things to obsess over. I chose flexible images. Issue № 343 Unfortunately, we can’t test bandwidth in any reliable way—not yet, at least. While we were working on the new Boston Globe website, we devised a technique to mitigate the size of requests for users that may have limited bandwidth. How responsive images worked#section1 Scott Jehl brilliantly masterminded Filament Group’s “responsive images” technique. There are three key components to our responsive images script: the markup, the JavaScript, and a server-side redirect rule.

It's no longer just embedded text background images and slices; it's interactivity and dynamic content, it's HTML5 and mobile development, it's JSON objects and Local Storage. No, I’m not talking about trying base jumping, I’m talking about how often you try new things in web design.

Recently, Louis Lazaris of Impressive Webs wrote an article titled “Skills for Front-End Developers” where he compiled a long list of “things” that a front-end developer (or web designer in my eyes) should know. There were forty-three items on this list, ranging from jQuery to the Canvas API. FEDe - A Search engine for Front-End (HTML,CSS,Javascript & jQuery) Web developers.

It also gave programmers the chance to give their webpages a more eye-popping look and website visitors were happier than ever. Despite the large number of developers that sing the praises of JavaScript, there are those Internet users who see its dark side. Webpages using multiple JavaScript codes are slow to load and overuse of JavaScript contributes to making webpages look cluttered and ugly. In no time the smart use of JavaScript became a hot topic amongst programmers. Without further ado, let us dive into our list of JavaScript best practices that will save you from this unwanted criticism.

You have read this a zillion times already. Use comments and white spaces while in development mode to keep your code readable.

In this tutorial we’re going to use jQuery and two plugins to gradually change a website’s background as the user scrolls the page. We’ll be using the Color Animation and Waypoints plugins. The Color Animation plugin adds animations to the color properties of elements. jQuery already includes an animate function, this plugin simply extends it. The Waypoints plugin allows us to execute a function when a user scrolls past a certain element. I’m sure it’s obvious how these two plugins will help us achieve our goal.

First things first, let’s set up our project folder. We can grab the newest version of jQuery here and put it in the js folder. We’ll use script.js to add the Color Animation and Waypoints plugins. The Markup The HTML markup in this tutorial is going to be very simple. Start by adding this code to index.html: Inside the div with the class container add the following code: <!
