I need to set two webpartzones in Horzontal way (side by side) and the third zone at the bottom of these two Zones. I need help in getting the webpart zones aligned horizontally. I used Designer manager to add the snippets and created the html file The extract of html file for the webpart zones is as follows
<div data-name="WebPartZone">
<!--CS: Start Web Part Zone Snippet-->
<!--SPM:<%@Register Tagprefix="WebPartPages" Namespace="Microsoft.SharePoint.WebPartPages" Assembly="Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxx"%>-->
<div xmlns:ie="ie">
<!--MS:<WebPartPages:WebPartZone runat="server" ID="xxcdxcxcxcxcxcx" TabIndex="1" BorderStyle="None" BorderWidth="0px" Height="38%" LayoutOrientation="Horizontal" Width="42%" AllowPersonalization="False" FrameType="None" Orientation="Vertical" Title="Zone1">-->
<!--MS:<ZoneTemplate>-->
<!--DC: Replace this comment with default web parts for new pages. -->
<!--ME:</ZoneTemplate>-->
<!--ME:</WebPartPages:WebPartZone>-->
</div>
<!--CE: End Web Part Zone Snippet-->
