Trying to find the right template file

[dre]

Hi there guys,

Im trying to edit something in the "postbit". Below i basically need to change width:95%; to width:100%;


Im struggling to find the right template although I presume its postbit because its when you've viewing a post.

<!-- / close content container -->
<form action="inlinemod.php?threadid=278&amp;p=" method="post" id="inlinemodform">
<!-- open content container -->

<div align="center">
	<div class="page" style="width:95%; text-align:left">
		<div style="padding:0px 15px 0px 15px" align="left">
