How to Create Graphical File Upload Progress Bars Using HTML5 and JavaScript
“In my previous posts, we discovered How to Use HTML5 File Drag & Drop, Open Files Using JavaScript and Asynchronously Upload Files Using Ajax. In the final part of this series, we cover the most exciting part of the process: graphical progress bars!
File upload progress bars provide essential user feedback but they’ve been notoriously difficult to implement. Until now that is. Both Firefox and Chrome support the XMLHttpRequest2 object which offers a progress event handler. But first, let’s consider how our progress bar will be implemented…”
Why You Should Start Using HTML5 & CSS3 Today

Many designers are complaining about the numerous ways how the lack of cross-browser compatibility is effectively holding us back and tying our hands keeping us from completely being able to shine and show off the full scope of our abilities in our work. Many are holding on to the notion that once this push is made, we will wake to a whole new Web full of exciting opportunities just waiting on the other side. So they wait for this day. When in reality, they are effectively waiting for Godot.
Just like the elusive character from Beckett’s classic play, this day of full cross-browser support is not ever truly going to find its dawn and deliver us this wonderful new Web where our work looks the same within the window of any and every Web browser. Which means that many of us in the online reaches, from clients to designers to developers and on, are going to need to adjust our thinking so that we can realistically approach the Web as it is now, and more than likely how it will be in the future.
Sometimes it feels that we are hiding behind the lack of cross-browser compatibility to avoid learning new techniques that would actually dramatically improve our workflow. And that’s just wrong. Without an adjustment, we will continue to undersell the Web we have, and the landscape will remain unexcitingly stale and bound by this underestimation and mindset.”
