- And we all know Google Loves HTML – Google Apps is a web based version of an office suite, but if that’s not enough, they also wrote a love story about HTML5And recently, on Google has been re-mixing their logo using adding HTML5 – this one is an interactive tribute to 20,000 leagues under the sea
- Silverlight FirestarterGu, Tim Heuer, John Papa, Jesse Liberty and other cogniscenti all to try and convince everyone that MS loved Silverlight and that seemed to have worked for a while, until last week’s MVP summit where the ASP.NET team were spotted rollin like this. Anyhow Microsoft clearly loves HTML5 AND Silverlight
- Native is for “high touch” things. Web is for low touch.
- FaceBook supports 18 native applications – too much! Moving to HTML5… even farmville!
- So we have 4 of the largest technology companies agreeing (to some degree) that HTML5 is the future… but
- What IS HTML5
- For the purposes of this talk I’t really 3
- So if we look at a typical page layout… divs and pretty common ID’s and Classes – which mean things to you and I, but not to the machine…
- With HTML5, we get new DOM elements, which have semantic meaning.
- Allows computers to “understand” the content better
- Gradients and rounded corners – help avoid using images on pages. We also have much wider support for web fonts, which now allows
- Also WebDB – relational database in the browser.
- As well as some other less widely implemented stuff
- Google Body Browser in Chrome to see what this is all about.
- So – HTML5 brings unicorsand rainbows to the world. Great… just
- There are two things to contend with
- The second problem is IE
- It’s not just that IE does not support HTML5 in any meaningful way, even more important is javascript performanceSo – the latest version of IE is >5 times slower than other more modern browsers. And IE 6 and 7 are more than double that!So the simple answer has been to use Flex of Silverlight
- Desktopvs tablets vs phones – very different screen sizes, and user xpectations
- This alone means that you need a separate “view” for touch devices – also note that Flex on Android != same app for desktop and mobile!
- So – what do we do? Multiple devices, form factors, javascript environments
- Since we have different needs for different client devices, lets drop the idea that we can create ONE thing and run it everywhere – use some infrastructure to create optimized views for each device.
