xf_openWeb is ready for download. Actually it is a flexible width theme, so take care what you display in centercolumn. Look into modultemplates and look for clearings which should not be there and for tables width=”100%”. This may force the content to be displayed after the content of left block.
When you want to use a fixed width version you can easily avoid this behaviour by setting an additional fixed width for “#contentArray1″ and “#contentArray0″. Play with the CSS settings and have fun.
