HTML5 Offline: Why It Makes Sense for Your Mobile Web Site

24/04/2013

HTML5 has been getting a lot of attention these past few years. And why not? It is an improvement to the very popular standard, bringing with it a lot of features that make HTML code writing a breeze while also making HTML5 Web sites greater for its visitors.

One of the things that HTML5 promises is the ability to be able let your customers access your mobile Web site even when they do not have an Internet connection. Yes, HTML5 allows your visitors to read your mobile Web site offline.

But it goes further than that.

HTML5's offline capabilities allow you to have your site load up almost instantaneously when visitors return to your site. This is because of application caching. The first time someone visits your site, their browser will keep a copy of the HTML, the CSS, images and other elements that are commonly used with your site. Because these elements are already cached, the next time they visit your mobile Web site, it will completely load in a jiffy! What's more, this will enable your visitors to use your HTML5 application, or at least some parts of it, without an Internet connection.

HTML5 also allows for offline storage. Think about when you play a game and you want to save your status or your progress. All you have to do is hit the save game button. HTML5 works in the same way in that you could store user-specific settings on the browser itself. Why is this important? Say you run a mobile Web site that features a simple game with different levels. If you do not have offline storage, you would be requiring the user to upload game details almost every five to ten seconds to make sure that he or she can keep his or her game updated. With offline storage, these updates may be kept current by saving them in the browser and then just uploading them at longer intervals.

The thing with having a mobile Web site is that not every smartphone is always connected to the Internet. People may turn off their data connection to save money, or they may be in places where they could not get one. This is why you should really look into using HTML5 for your mobile Web site!
