Hi, any micro-format, and two column theme can be used, such as Avada or Newspaper theme. But no matter what theme we use, it needs some very good modification.
On the diamon hill site, i see they have created a custom theme, it's not so designed, but everything arranged as needed. Like, on the about page, they have used floating menu to reach each department members area, on strategy pages, they interlinked each strategy sub-sections. Its the best presentation.
To after creating/changing a theme to that format, we can scrap all of the pages they have, and then modify it manually. That what you need right - all of the feature + all of the content ?
Thanks.
