HTML5 Canvas標籤範例
隨著時代的進步，HTML的版本一直在進化，目前比較新的版本應該就是HTML5了，這次的HTML5針對許多標籤進行調整，當然也新增了一些標籤，主要的目的是希望可以將一些本來需要利用Flash才可以完成的互動頁面取而用HTML5來進行設計，這樣比較能減輕網頁的負載，但不管怎麼進步，其最重要的目的當然還是要網友能夠看到才行！
目前各家的瀏覽器對於HTML5的支援都不一，如果想要測試看看自己所使用的瀏覽器對HTML5的支援程度，可以到這個網址測試，馬老師針對目前的三款瀏覽器（IE9、Firefox6、Chrome13）來做了測試，IE9於HTML5中測試得到了以下的分數：
Firefox6於HTML5中測試得到了以下的分數：
Chrome13於HTML5中測試得到了以下的分數：
所以用以上的結果來看，目前是Google Chrome對於HTML5的支援最好，不過也只是拿了450分中的340而已，所以是否要全面改用HTML5來開發，還是應該要好好的斟酌一下，但是先了解HTML5能做到的功能，一定是沒問題的！以下就是馬老師針對HTML新增的畫布標籤製作的範例，不過因為瀏覽器支援的關係，必須使用Chrome觀賞才會是比較完整的功能喔！

im.src = "img/p" + i + ".jpg";
photos.push(im);
}
function slideshow(){
context = document.getElementById('canvas').getContext('2d');
setInterval(loop,10);
}
function loop(){
x += (slider.value - x) * 0.1;
ind = Math.floor(x/800);
offset = x % 800;
context.drawImage(photos[ind], offset, 0, 800-offset, 600, 0, 0, 800-offset, 600);
context.drawImage(photos[ind+1], 0, 0, 800, 600, 800-offset, 0, 800, 600);

Great blog post. Some tips i would like to bring up is that personal computer memory must be purchased but if your computer can’t cope with anything you do by using it. One can put in two RAM boards having 1GB each, by way of example, but not one of 1GB and one having 2GB. One should check the company’s documentation for own PC to make certain what type of memory space is necessary.
