The above code is from default-widgets.php (under wp-includes) and its for Recent Comments widget. Now you can insert any html to widget title. The "italic" highlighted code need to be removed and instead the "bold" highlighted code should be there..

Similarly you can do the same thing for other widgets too..

Hi,

Here is the better way as explained in the tutorial i mentioned. Don't do the changes in default-widgets.php

Instead,

upload the attached file to your theme folder and add the following to your functions.php

if (include('custom_widgets.php')){
add_action("widgets_init", "load_custom_widgets");
}
function load_custom_widgets() {
unregister_widget("WP_Widget_Recent_Comments");
register_widget("WP_Widget_Recent_Comments_Custom");
}

Now you can have html tags in your title.. Here is the working demo

http://www.comnedy.com/widget-title/

In the sidebar widget Most Recent Comments - I put the title as Most <span>Recent</span> <strong>Comments</strong> - And its working.. Have a try. It should work. In the similar way you can do for other existing widgets.

Sorry, The file is not being attached. Here is the code you need to paste in custom_widgets.php


<?php
