.content .r3
{
-khtml-border-radius: 3px;
-webkit-border-radius: 3px;
-o-border-radius: 3px;
border-radius: 3px;
}
.sidebar .r4
{
-khtml-border-radius: 4px;
-webkit-border-radius: 4px;
-o-border-radius: 4px;
border-radius: 4px;
}
Also you could declare many elements and use the same class like.
.navigation .r,
.content .r,
.sidebar .r
{
-khtml-border-radius: 3px;
-webkit-border-radius: 3px;
-o-border-radius: 3px;
border-radius: 3px;
}
.sidebar-2 .r,
.sidebar-home .r
{
-khtml-border-radius: 4px;
-webkit-border-radius: 4px;
-o-border-radius: 4px;
border-radius: 4px;
}
Add a bit of code in functions.php to create a new sidebar, then a file for the new sidebar sidebar-home.php
<?php if ( ! dynamic_sidebar( 'sidebar-home' ) ) : ?>
<p><?php echo __( 'Add widgets to the Home Sidebar, Admin > Appearance > Widgets', 'themenamespace' ); ?></p>
<?php endif; ?>
Then call it in home.php or index.php a page file.
<div class="sidebar-3 r">
<?php get_sidebar('home'); ?>
</div>
