: Any tips for good tutorials or discussions on web page animation? The simple effect I'm ultimately after is this: load an image in the centre of a web page have the image slide across to
The simple effect I'm ultimately after is this:
load an image in the centre of a web page
have the image slide across to the left
then start loading other text and images around it
I don't mind how many separate web pages are required to do this, or how many separate images, but I'd like to know what my options are. I am more programmer than graphic designer, so maybe I'm searching using the wrong technical terms. Maybe "animation" is too grand a term for so simple an effect, but "slide" has other connotations in this context, and between those two things, I'm struggling to find a clear way to a clear answer. I would ultimately like to understand things like:
Can the above task be achieved with one image on one page, in HTML, without scripting?
Does HTML only support "static" elements that appear on screen, and never change their position? If that is the case, does all animation therefore rely on either having (static) elements with dynamic content, or repeatedly loaded/rendered static elements which give an appearance of movement?
How widespread is browser support for the various animation options?
So as the original question suggests, maybe a tutorial would be good. I haven't found a decent one of those yet either!

To specifically cover these points:
Can the above task be achieved with one image on one page, in HTML,
without scripting?
You could just about fake it with one great big animated GIF embedded in an HTML page, but it wouldn't be an elegant solution. This really needs scripting and CSS.
Does HTML only support "static" elements that appear on screen, and never change their position?
Strictly speaking, yes. However an HTML page may also include embedded CSS and Javascript code which may add animation; it would be more common to have the bulk of the CSS and Javscript in separate files.
If that is the case, does all animation therefore rely on either having (static) elements with dynamic content, or repeatedly loaded/rendered static elements which give an appearance of movement?
More static elements (containing images, blocks of text, or empty to start with) with movement or their content loaded by scripts.
But I would definitely suggest using HTML + CSS to statically position elements first, before looking at any scripting or animation.
For a "pure HTML" solution, you're going to want to look at CSS3 Animations: www.w3schools.com/css3/css3_animations.asp
However, if you're looking for cross-browser compatibility, this is not the way to go. As you can see on that page, IE does not support this yet.
I would use javascript for a more cross-browser friendly solution. A good library to use might be jqueryui: jqueryui.com
