Part 4 - How to change columns width
Content area on a site where Flow Plone Skin installed is subdivided into three columns: column one and two are usual portlet column, column three - is a content area.

Column width can be changed: we define first and third column width, and the second column width is generated on the basis of the other two.
1. How to change column width through Zope Management Interface
Go to ZMI interface and select portal_skins in the left navigation menu.
In portal_skins contents select qploneskinflow.

This folder has base_properties document,

that contains information about Plone's color, logo ans border defaults:

Now column one width is 234px, column two width is 174 px. In case you want to change these numbers press Customize button. In the opened window change columnOneWidth value from 234px to your new column width,and columnTwoWidth from 174px to new value. Do not delete px.
Let's put, for example, columnOneWidth value = 200px, than columnTwoWidth value = 250px.

Save changes. Now return to Plone Interface and you'll see your changes applied: column one narrowed (from 234 to 200px), column two widened (from 174 to 250px) with navigation items lines widened as well.

2. How to change column width through File System
There is a base_properties document in qploneskinflow folder:
Open it and you will see the list of main skin properties: Plone's color, logo and border defaults:

Now column one width is 234px, column two width is 174 px. In case you want to change these numbers - change columnOneWidth value from 234px to your new column width,and columnTwoWidth from 174px to new value. Do not delete px.
Let's put, for example, columnOneWidth value = 200px, than columnTwoWidth value = 250px.
Save changes. Now restart server so that changes are applied. When you get back to Plone interface you will see your changes applied: column one width narrowed, column two widened with navigation items lines widened as well.
