Hi, there's an addon approved by OCA named \"Report Qweb Element Page Visibility",
This module adds classes such as "first-page" to suits your needs.  This module supports upto v10, if you need v11, just change the report module name to web.

You will need to either Create your new layout or override the existing "web.external_layout".

Based on the layout style setting, the "web.external_layout" will call layout styles such as "external_layout_standard" or "external_layout_clean">

In the layout style, add attribute class="first-page", it will look similar to this<div class="first-page col-xs-5 col-xs-offset-1" name="company_address">
