From SharePoint 2013 -If I create a publishing sub site called "Media" and I want to customize the master page for all site pages within this Media sub site, what steps must I take to complete this without changing the administrative pages (i.e. pages in site settings, design manager, etc...). They all use olso.
I want a full customization (master page editing), of just the site pages within this specific sub site.
I may have 100 site pages within this sub site, and want them all to use a single custom master template. Nothing else in this sub site should use this custom master template.
