Display posts in columns

split your post content in columns,
format your posts thts way:

potential content goes here that appears before the columns.
[--column--]
Content for column 1 here.
[--column--]
Content for column 2 here.
[--column--]
Content for column 3 here.

use the following code within the wp loop in your your single.php file

<?php
$page_columns = explode("[--column--]", $post->post_content);
print $page_columns[0];
print '<div class="column first">';
print $page_columns[1];
print '</div>';
print'<div class="column second">';
print $page_columns[2];
print '</div>';
print '<div class="column third">';
print $page_columns[3];
print '</div>';
?>

now style it

.column{
width:33%;
float:left;
margin-right:10px;
}

column.first, column.second, column.third, {
/* Customize to fit your needs */
}

Dynamic Highlight Menu

control the current selected menu tab in CSS by adding a class="current" on it.

< ul id="nav" >
< li<?php if ( is_home() || is_category() || is_archive() || is_search() || is_single() || is_date() ) { echo ' class="current"'; } ?>>< a href="#" >Gallery< /li>
< li<?php if ( is_page('about') ) { echo ' class="current"'; } ?>>< a href="#">About</li >
< li<?php if ( is_page('submit') ) { echo ' class="current"'; } ?>>< a href="#">Submit</li >
< /ul>

Line 2:

If Home, or Category, or Archive, or Search or Single page is selected, class="current" will be included in
Line 3,4:

If Page with page slug about or submit is highlighted, class="current" is added.

If you are looking at putting categories as menu tabs, here’s how to make the menu dynamic:

< ul id="nav">
< li<?php if ( is_category('css') ) { echo ' class="current"'; } ?>>< a href ="#">CSS< /a>< /li>
< li<?php if ( is_category(showcase) ) { echo ' class="current"'; } ?>>< a href ="#">Showcase< /a>< /li>
< /ul>

Line 2,3

If category with category slug of css or showcase, class="current" is added.</ li>
