Three-Tiered Approach

In TheGem, Theme Options are built reflecting the flexible three-tier template hierarchy approach. Sounds complicated, but very easy in use: 

Tier 1: Theme Options allow you to make global website setup, which will be automatically applied to all single pages & posts and all archive pages (see “Global Website Settings”) .   

Tier 2: Additionally, you can make separate  settings for chosen types of single and archive pages (posttypes) , which will differ from global settings and will apply only on this selected types. For example, if you wish, that all your blog posts or product categories have different layout & styles than the rest of your website, you can easily make this custom settings in Theme Options (see “Single & Archive Pages”).   

Tier 3: And finally, using Page Options, you can setup individual pages, posts, products etc. to look differently than set for the whole website (Tier 1) or for the selected posttypes (Tier 2).
