Adding bootstrap apps inside a Page Viewer Webpart

Problem:  Adding a bootstrap app inside a page viewer web part in SP2010 causes the formatting to be messed up. Reason:  SP 2010 does not have the right compatibility mode required on the master page. Solution: Open the site in SharePoint Designer Copy the v.4 master page for the site to a new master page and add the following line as the first "meta" tag:  <meta http-equiv="X-UA-Compatible" content="IE=10" /> Click save as default master page on the ribbon.  Keep in mind this applies to all pages to the site.
