Global Content by BusinessBox allows you to define at only one place some content globally used all over your website.
Hence it prevents from writing mutlitple times some hardly-maintenable text.
Plain text as well as more complex HTML/CSS code can be put in each of those global variables.
Simply use this content in either your templates by using our PHP function <code>gcbb_get</code> or directly in the content of posts or pages using a modifiable tag such as <code>[GCBB#variable]</code>.
