Block if visibility

[jont]

When a Block if condition is false it in effect sets the equivalent of display:none (in CSS terms) ... this is causing issues with layout ... is it possible to use the Block if with display:hidden to maintain white space formatting?

Hoping not to have to hack around setting more CSS values

Might be a solution to have a second block if for the opposite condition - in effect a block else

More blocks than Lego

Assuming the concept works (not at a Actinic machine) how could the containing Block If know how much space to re-alloacte back to the page as white space

Think probably best to stick to CSS and position the elements so if one is removed from the flow the others do not occupy the space.

[wjcampbe]

My thinking was

Block if evaluates true and occupies a x b space
Block if not evaluates false and does nothing

or

Block if evaluates false and does nothing
Block if not evaluates true and occupies a x b space (same dimensions)

Unless we have something that isn't NOT when it is NOT is - like < 0, > 0 and = 0.

You're probably right, CSS positioning is likely easier

You can use block ifs in the CSS file if that's any help.
