With each major update IOS always come many changes, some visible to the naked eye for most users and others more subtle enough that those who seek them. The latest version of Safari to increase support for HTML5 currently included in the beta 5 of the IOS, good news for web developers.
Of all the changes are good and less good is the possibility of using position: fixed, overflow: scroll, a new type of input (range of dates, hours or months), the use of the increase in JavaScript. If not, we can’t access pictures or video to upload from your browser. Something that would be very useful and missing persons who attempted to publish to your blog from IPAD, for example.
However, all is not said. Being a beta version is included in the system, it is possible that other changes in the final version we will have with the launch of five IOS in the fall, for better or worse it could be modified or deleted a number of things. For those who want to test and scoring, IOS 4.3.3 IOS scored 206 while the total 5267 of the implementation of the HTML5 test.
