Suggestion: windows tag
Usage: If you want to create a modal form/window, a “popup” or a lightbox you have to use Javascript. I am suggesting this tag to remove the javascript need to create such a standard feature on the web. This technique uses iframe and css to create the look.
Implementation: I am suggesting that
Adding the following attributes:
- modal
boolean, if the window shall be modal or not - movable
boolean, true if the window shall be moveable, false if not - fade-background-color
Color, set the background color being used when window opens. Default is dark gray… - background-opacity
integer, set the transparency for the background
I am not part of the W3 HTML 5 working group and I have not posted this suggestion to this group. I am just suggesting it here as something I wish to see in HTML 5.
