Sometimes i dont even notice things like this, as i look at them all day and go, ah yeah thats a search box. I forget that all these things can be fixed. 

Anyway, even just adding this form to a card will make it look neater. 

Yep i think thats better

Just add the search form to a card using the following card.html template. 

$search_card = new template("card.html");
$search_card->set("title", "Search");
$search_card->set("content", $search_form);

and then replace this

//$page_content .= $search_form;
$page_content .= $search_card->output();

/end
