There are three main reasons why front-end performance is the place to start. 1) There is more potential for improvement by focusing on the front-end. Cutting it in half reduces response times by 40% or more, whereas cutting back-end performance in half results in less than a 10% reduction. 2) Front-end improvements typically require less time and resources than back-end projects (redesigning application architecture and code, finding and optimizing critical code paths, adding or modifying hardware, distributing databases, etc.). 3) Front-end performance tuning has been proven to work. Over fifty teams at Yahoo! have reduced their end-user response times by following our performance best practices, often by 25% or more. Steps to increase the performance of a site: 1) Minimize HTTP Requests 2) Use a Content Delivery Network 3) Add an Expires Header 4) Gzip Components 5) Put Stylesheets at the Top 6) Put Scripts at the Bottom 7) Avoid CSS ...

There is a nice technique to reduce the amount of calls your browsers has to make to the server. This will be every image, every css and every JavaScript file included in the webpage. Each time you want to load in one of these elements you will be sending a request to the server which will return the requested object known as a HTTP request. Reduce Page Loading Time With PHP Each one of these uses up time on your page loading, so to reduce page load all you have to do is reduce the amount of calls being made. But what if you want to organise you JavaScript files, jquery file, general file, application file and page file. There could be upto 4 requests for some javascript for the page. It is possible in PHP to combine these JavaScript files together and trick the browser into thinking they are just one JavaScript file, therefore reducing the amount of calls being made to the server. This is done by reading the JavaScript with PHP then changing the header to JavaScript like the ...

HTML5 <video> - DOM Methods and Properties HTML5 has DOM methods, properties, and events for the <video> and <audio> elements. These methods, properties, and events allow you to manipulate <video> and <audio> elements using JavaScript.

HTML5 brings a host of new elements and attributes to allow developers to make their documents more easily understood by other systems (especially search engines!), display data more uniquely, and take on some of the load that has required complex JavaScript or browser plug-ins like Flash and Silverlight to handle. Here are 10 new items in HTML5 that will make it easier for you to write your Web sites. 1: <video> and <audio> One of the biggest uses for Flash, Silverlight, and similar technologies is to get a multimedia item to play. With HTML5 supporting the new video and audio controls, those technologies are now relegated to being used for fallback status. The browser can now natively display the controls, and the content can be manipulated through JavaScript. Don’t let the codec confusion scare you away. You can specify multiple sources for content, so you can make sure that your multimedia will play regardless of what codecs the user’s browser supports. 2: <...
