Going to start using HTML5 as much as possible. Partially supported by IE9 browser (IE9 doesn’t support HTML5 animation) . Well supported on Firefox and Chrome.
I like how it is done in javascript; however, javascript does not hide your IP.
How to enable HTML5 on your webpage
To use HTML5 on a webpage, just add the following tag at the top of the page:
This replaces the tag for a version of HTML4 such as:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Note for BlogEngine.NET
Change the DOCTYPE tag in the theme site.master file and rebuild/re-deploy the website.
Example of HTML5
Here's an example of drawing a red rectangle in a canvas tag:
<script type="text/javascript">
window.onload = function ()
{
drawRectangle();
}
function drawRectangle()
{
var canvas = document.getElementById('drawingCanvas');
if (canvas.getContext)
{
var context = canvas.getContext('2d');
// draw rectangle normally
//context.fillStyle = "rgb(255,0,0)";
//context.fillRect(2, 2, 250, 200);
// draw rectangle with shadow
context.rect(2, 2, 250, 200);
context.fillStyle = "#FF0000";
context.shadowColor = "#BBBBBB";
context.shadowOffsetX = 20;
context.shadowOffsetY = 10;
context.fill();
} else
{
alert("Your browser does not support HTML5!");
}
}
</script>
<canvas id="drawingCanvas" width="260" height="210"></canvas>
If you don't see the rectangle and you get a alert message, your browser does not support HTML5.
