While ago I've published proposal about different layout managers and
flex units in CSS:
http://lists.w3.org/Archives/Public/www-style/2009Apr/0154.html

Display template is one of layout managers that it covers.

Say you have some list (<ul>) and you need to replace its items in rows
having three cells each:

ul
{
   flow:horizontal-flow; /* bricks in the wall layout */
}
ul > li {
   height: 1*; /* li height spans full row height */
}
ul > li:p:nth-child(3n+1)
{
   width: 25%; /* first column, fixed width */
}
ul > li:p:nth-child(3n+2)
{
   width: 1*; /* second column, flex = 1 */
}
ul > li:p:nth-child(3n+3)
{
   width: 2*; /* third column, flex = 2
                 two times wider (if space allows)
                 than second */
   clear: right; /* each third items ends row, row break after it */
}

Rows here can have variable number of items in them - matter
of clear:right | left definition.

Different cases require different layout managers. For master page
layout template is pretty good. Even for the long lists I saw it being used.

li /* each item in this (long) list is defined
       by the template: */
{
   flow: "a a b"
         "c d e";
}
li > div.caption   { float:"a"; }
li > div.price     { float:"b"; }
li > div.note      { float:"c"; }
li > div.principal { float:"d"; width:1*; }
li > div.rebate    { float:"e"; }

I suspect that flex units are what you are looking for.
