Columns with CSS not working

1

I’m pretty sure that this used to work:

With the following in a tiddler tagged with $:/tags/Stylesheet
.twocolumns { display:block; column-count:2; -moz-column-count:2; -moz-column-width:20px; }

This would show the tag list in 2 columns:

@@.twocolumns
{{{ [tag[Concepts]] }}}
@@

But not anymore.

Have I missed something?

Try this instead. The triple curly braces, filtered transclusion may be the issue.

@@.twocolumns
<$list filter="[tag[Concepts]]">

</$list>
@@

Thanks, Tones, but that didn’t do it.
I’m trying this at tiddlywiki.com

@@.twocolumns
<$list filter="[tag[Filter Operators]]"><br>
<$link/>
</$list>

Ah!! I needed a space after @@.twocolumns

Thanks

Replied before seeing your post - yes, that probably does the same thing - thanks

Yes, after playing around altering spaces and lines in the initial options with different results, I can see this seems to be the most robust way of doing it - thanks.
