Some web loading animations effect I wrote via using HTML/CSS + JQuery

this demo shows how to set the loading animations with a specific time (3s in my example).

note : this is not the best practice, but for some case it's handy.

this demo shows how the loading animations faded out as soon as the web page is rendered. It's more pratical than demo1 because it's not set by time.

note: please clean your cache during test otherwise the effect may be less significant to notice.

this demo using CSS3 to build the animations. CSS3 is greater than GIF loading methods in terms of the size and execution time.

this demo shows a top-fixed bar loading animations and when the page was loaded, it's fade out automatically. You can cusomize the color and bar height in stylesheet.

This demo shows a complicated loading animations based on the real loading process and display percentage loading.

In this demo the new Image() object , complete property , onload, onerror, onkeydown, onkeypress Event was being used.

note: be sure to put src behind the onload event to avoid display error in IE brower.
