Open Source Resources for Web Application Developers

Would you like the Scrolling Background Effect like youlove.us? The technique is actually a lot simpler than it looks, it’s based around scrolling a very tall gradient image behind some transparent PNG images. The header image has a transparent background and solid text, while the main page is actually an image with the heading text as transparent cut outs.

The JavaScript is where the real magic happens. They have made use of the jQuery library and Alexander Farkas backgroundposition.js script to help them make the background move. The final result looks very nice. However, it might consume a lot of your CPU resources.

With 200 lines of JavaScript, you can drag and drop table content. Content of the HTML table cells can be dragged to the another table cell or another table. Script has built in autoscroll and option to forbid landing to some table cells. Table could have rowspan or colspan cells and different background color for every cell.

In order to detect destination table cells, script calculates all table cell coordinates / dimensions and store them to the arrays. Arrays are searched inside onMouseMove handler and when user release left mouse button, object will drop to the current table location.

Requirements: FireFox 3, Internet Explorer 6 and Google Chrome

While mimicking the OS X dock and stacks isn’t new, it’s certainly not common. Nettuts has shown us a few ways to do “Outside the Box” Navigation with OS X style docks and stacks navigation.

jQuery OS X Stack and Drop Stack is my favorite navigation style out of the three shown in the tutorial. It’s super lightweight (~1kb). It might be a little awkward having the navigation in the bottom right or left of the browser window but it would certainly be creative and save lots of space.

Many websites offer syndication formats such as RSS, JSON, or XML based services to allow for easy content delivery. But what happens when a website doesn’t offer one of these services? How do you syndicate content from a website that doesn’t offer a news feed?

Nettus has gaven us a a simple solution using JQuery’s AJAX functions and PHP’s cURL library that allows us to syndicate external content. This is a simple solution if you require content from an external website.

Although JQuery’s easy syntax and CSS-selectors give us the convenience of styling and selecting what we want from the client-side, this is not speed optimized. Remember you have no control over whether or not the content creator changes what tags and classes they use, it is always best to style general elements that will be commonly used.

jQueryforDesigners has added a scrolling carousel that worked in the same way the carousel worked on the Apple Mac ads page. They have published a tutorial which walk through the fundamentals of scrolling carousel, and how they have created jQuery Infinite Carousel.

The trick is building the DOM with the cloned nodes, because we’ve cloned the start of the list to the end of the list, when we scroll off the last items, it looks like we’ve looped back round. Once the animation completes, we change the scrollLeft position back to the real first items.

This scrollLeft isn’t visible to the user since the overflow is hidden, and so it creates the effect of being infinitely sliding from left or right.

Currently, there are two commonly used techniques on displaying columns, the fixed columns and the liquid columns. With fixed columns, there will be certain viewport resolutions, where it leaves excess white space where a column was just not able to squeeze in. The downside of liquid columns is that we are restricted to having a fixed number of columns per row.

SohTanaka has thought of a solution: Smart Columns with CSS & jQuery would be able to benefit the situations is to take the good of both scenarios and mash it into one. Allow as many fixed columns to line up across the viewport. Take excess white space and evenly distribute them to each of the columns to complete the full row. This way the columns will always fit perfectly.

And also, It keeps a default fixed width as the base, so that the columns are reasonably within the intended columns sizes while maintaining enough flexibility to accommodate for the expandable viewport.
