[css3-multicol] column-span property

Hello community,


[CSS3COL] specifies a new property column-span to have a static, non-floating 
element span multiple columns.
I would like to see the capabilities of column-span extended to:
* Be allowed for floating boxes and maybe others as well if applicable.
* Allow percentages.

If a floating box has its column-span property set, the column-span property 
specifies how many columns the floating box should span. For a floating box, 
either the width or the column-span property can be set. If both are set, the 
column-span property takes precedence. The column-span property is an 
alternative way to set the width taking the size of the column-gap into 
account. The effective width calculated on the base of the column-span is: 
width := column-span * column-width + floor(left + column-span / 100%) * 
column-gap.

Examples:
* A float with left:0%; and column-span:200%; should span two columns 
including the gap between them.
* A float with left:50%; and column-span:200%; should span three columns, 
starting in the middle of the first of those three and ending in the middle 
of the last of those three, including two gaps between them.
