Relative width CSS classes for theme layouts

To assist with making the elements of a page responsive to various widths, relative width CSS classes have been added to the theme layouts. These classes are marker classes only. There are no styles that are defined for these classes by default. They are there on the containers, rows and columns, of the layouts so that you can define your own styles that are associated with the classes as needed to make your page elements responsive to various widths.

There are two types of relative width classes, and one of each is used on each layout container.

Semantic type, one of:
wpthemeThin
wpthemeNarrow
wpthemeMedium
wpthemeWide
wpthemeFull

These types allow for up to five variations in width and are described by using common width words, such as narrow and wide.

Grid type, one of:
wpthemeCol1of12
wpthemeCol2of12
wpthemeCol1of5
wpthemeCol3of12
wpthemeCol4of12
wpthemeCol2of5
wpthemeCol5of12
wpthemeCol6of12
wpthemeCol7of12
wpthemeCol3of5
wpthemeCol8of12
wpthemeCol9of12
wpthemeCol4of5
wpthemeCol10of12
wpthemeCol11of12
wpthemeCol5of5
wpthemeCol12of12

These types allow for up to 16 variations in width and are described by using a numbering system of nofn width units. At first glance it looks like a simple numbering system where a layout with five columns would use wpthemeCol1of5, wpthemeCol2of5, wpthemeCol3of5, wpthemeCol4of5, and wpthemeCol5of5 to number the columns. However, the best way to look at this system is not as the number of the column, but rather as the number of width units that the column takes up on the page. So, wpthemeCol2of5 means that the column takes up two of five width units of the page, or 2/5ths of the width of the page, and wpthemeCol8of12 means that the column takes up 8 of 12 width units of the page, or 3/4ths of the width of the page. So, a layout with five columns of equal width would use wpthemeCol1of5 on all of the columns.

The two class types map to each other in the following way:

Width of the page Semantic Type Grid Type
1/12th wpthemeThin wpthemeCol1of12
2/12ths (1/6th) wpthemeThin wpthemeCol2of12
1/5th wpthemeThin wpthemeCol1of5
3/12ths (1/4th) wpthemeNarrow wpthemeCol3of12
4/12ths (1/3rd) wpthemeNarrow wpthemeCol4of12
2/5ths wpthemeNarrow wpthemeCol2of5
5/12ths wpthemeMedium wpthemeCol5of12
6/12ths (1/2) wpthemeMedium wpthemeCol6of12
7/12ths wpthemeMedium wpthemeCol7of12
3/5ths wpthemeMedium wpthemeCol3of5
8/12ths (2/3rds) wpthemeMedium wpthemeCol8of12
9/12ths (3/4ths) wpthemeWide wpthemeCol9of12
4/5ths wpthemeWide wpthemeCol4of5
10/12ths (5/6ths) wpthemeWide wpthemeCol10of12
11/12ths wpthemeWide wpthemeCol11of12
5/5ths (1) wpthemeFull wpthemeCol5of5
12/12ths (1) wpthemeFull wpthemeCol12of12
The Semantic types maps to the following page width amount:

Semantic type Amount of the page width
wpthemeThin 1/12th to 1/5th
wpthemeNarrow 1/4th to 2/5ths
wpthemeMedium 5/12ths to 2/3rds
wpthemeWide 3/4ths to 11/12ths
wpthemeFull all
