satimis on "Full width page - theme twentythirteen"

Hi all,

I was following;
Full Width Page Template
http://wordpress.org/support/topic/full-width-page-template-2?replies=26

to edit full width page but failed.

1)
Steps performed as follows;

child style.css

/*
Theme Name:     Twenty Thirteen Child
Theme URI:      http://sousvide.reynoldstocks.com/
Description:    Child theme for the Twenty Thirteen theme
Template:       twentythirteen
Version:        0.1.0
*/
@import url("../twentythirteen/style.css");
body .site-header {
background-size: 100%;
}
.entry-header-full,
.entry-content-full,
.entry-summary-full,
.entry-meta-full {
	margin: 0 auto;
	max-width: 1110px;
	width: 95%;
}

copied page.php to "child theme" and renamed it full-width.php

changed;
.entry-header to .entry-header-full,
.entry-content to .entry-content-full,
.entry-meta to .entry-meta-full

Couldn't find .entry-summary

2)
Rename full-width.php back to page.php

Still failed

Please help. Thanks
