I have successfully created the master page (Sharepoint 2013) and layout page from html file but unable to add webpart zones to the body.
<div id="maincontentcontainer">
<div id="maincontenttop">
</div>
<div id="maincontentbottomleft">
</div>
<div id="maincontentbottomright">
</div>
</div>
<div id="rightsidebarcontainer">
<div id="rightsidebar">
</div>
</div>
this is the body stucture and i want to add webpart zones or content placeholders to these divs(to be able to add webparts). any help in doing this would be great thanks.
