Changing Widths:
My best advice is to use the following css to change widths of the sidebar and main content area. Just add it to syle.css in your child theme
@media only screen and (min-width: 64.063em) {
#container.large-8 {
width: 75%; /* your custom percentage */
}
#main .large-4 {
width: 25%; /* your custom percentage */
}
}
Richard: Wouldn’t altering the division of columns to 9 and 3 be more in accordance with the Foundation way? Or is there some reason why sticking to 8 and 4 columns is more advisable?
line 207 of widgets-extensions.php handles the code for the main container
function cleanyetibasic_container()
It basically changes the width from large-8 to large-12 based on whether or not the full-width page template is chosen or if the sidebar is active.
I figured using css would be an easier way around than editing the files.
you would also have to edit sidebar-extensions.php
Also found a good link on overwriting functions in your childtheme here:
http://venutip.com/content/right-way-override-theme-functions
so you could do something like
function remove_container() {
remove_action( 'cleanyetibasic_abovecontent', 'cleanyetibasic_container', 1 );
}
add_action( 'init', 'remove_conatiner' );
function childtheme_container() {
...
}
add_action( 'cleanyetibasic_abovecontent', 'childtheme_container', 1);
I justed realized this won’t work with cleanyetibasic_sidebar()
I’ll revise the code so that it the opening element for the sidebar uses an action.
Works like a treat in 2.0.3:
// Add custom sidebar
function my_sidebar_open( $open ) {
$open = '<div class="large-3 columns">';
// echo apply_filters('cleanyetibasic_sidebar_open', $open);
return $open;
}
add_filter( 'cleanyetibasic_sidebar_open', 'my_sidebar_open', 1);
