Without Major Modifications into the Theme, but only with Additions to the Hybrid WordPress Theme Functions
Well, I am not the one to be happy for this. Credits must go to Justin Tadlock, the author of the robust and comprehensive WordPress Theme, Hybrid WordPress Theme Framework, the user-friendly, search-engine optimized parent theme, featuring 15 custom page templates and multiple widget-ready areas and for the YUI Grids implementation theme functions to Victor Goh, the author of a WordPress called yui-css-grid, A YUI Grid CSS based WordPress theme. YUI Grids CSS. This theme is based on the yui-app-theme and comes with 8 color schemes, 5 page widths and 6 layout combinations. Color scheme – dark blue, facebook, green, greenish, orange, purple, red, tan blue and custom. Page width – 750px, 950px, 974px, 100% fluid and custom. Page layout – 6 combinations of right and left sidebar with different widths. Customize your theme using the Dashboard menu Themes > Customize Theme after installing this theme.
With this modifications, I am now able to style the Hybrid Theme Framework and display them with YUI GRIDS layout.
The YUI GRIDS Layout has some the choices #doc, #doc2, #doc3, #doc4 and #custom_doc with varieties of left or right sidebars.
It is worth to notice as well that I also added two more menus, i.e., Footer Menu as an additional menu for joined after the Primary Menu Navigation (Page Menu Navigation) of the Hybrid Theme; and secondly I also added functionality for disabling and enabling subsidiary and secondary sidebars in singular.php and page-single page display. There is also Login/Logout Menu added here, copying from another verison of of Hybrid Theme called News WordPress Theme developed by Justin Tadlock and his colleague at DevPress.
All of my themes will apply the same Navigation Menus as well as the disable/enable functionality for sidebars.
