After having completed one piece without using Flash http://www.ABCsofUFOs.com, I am trying it again. Anyone who has used Flash knows how versatile it is. The empty canvas of the Flash stage offers limitless possibilities as to what can be created, and it is not fussy about how you get there. Throw down some digital "paint," and does Flash ask if Internet Explorer will be able to see it? Mix in some code, and does it beg (like Internet Explorer) for another snippet or two even though no other browser in the world requires it? Flash is forgiving, and Flash is not at war with the rest of the world, like IE is. A Flash file always works in IE (as long as the player is installed), but when it comes to html/CSS/Javascript, it's another game entirely.
Which makes it so difficult to leave Flash behind and work in HTML/CSS/JavaScript. In this realm, it's a daily struggle to make things happen that, in Flash, would take ten minutes. You name it--tweening, swapping images, adding sound, shaping text--in Flash it's, well, a flash.
Another thing that bothers me is that in html, it's all essentially squares and rectangles. Sure, you can make a shape, but positioning it on the page is nowhere as easy as in Flash, where it's basically just drag and drop. Am I alone in this? Do I know so little, having traded quite a lot in Flash for the miniscule amount of what I know in html/CSS/Javascript?
Right now, my frustrations are tempered somewhat by the few successes I gain. But it's difficult, and I am not sure html/CSS/Javascript is up to what I can imagine for the page.
