Add Page Element Blogger

When we need a design element in blogger, just for example if we want to add a widget in the header or above the initial post, then we need to add the element.

Or it could be said we turn on the elements that have been there a way to change it by editing the html.
Here's how.

Add Page to Header.
Find this code:
<div id='header-wrapper'>
<b:section class='header' id='header' maxwidgets='1' showaddelement='no'>

Replace it with:
<div id='header-wrapper'>
<b:section class='header' id='header' maxwidgets='3' showaddelement='yes'>

Add Page to Main.
Find:
<div id='main-wrapper'>
<b:section class='main' id='main' showaddelement='no'>

Replace with:
<div id='main-wrapper'>
<b:section class='main' id='main' showaddelement='yes'>
