Hi there.
If you would like to have that the first letter of your content get the css "dropcap" which makes the first letter bigger and adds nice typo to your blog, add this function to function.php in your theme or better your child theme:
function wpguy_initial_cap($content){
// Regular Expression, matches a single letter
// * even if it's inside a link tag.
$searchfor = '/>(]+>)?([^<s])/';
// The string we're replacing the letter for
$replacewith = '>$1<span class="dropcap">$2</span>';
// Replace it, but just once (for the very first letter of the post)
$content = preg_replace($searchfor, $replacewith, $content, 1);
// Return the result
return $content;
}
// Add this function to the WordPress hook
add_filter('the_content', 'wpguy_initial_cap');
