I'm experienced with Latex but more or less plain Latex without much graphical content. Anyway, I'm trying to create a template for invoices and other official documents. Therefore I want a simple design that follows a corporate identity.
Question: But I have no idea how to add those blue lines both to the title page and to the default page style (odd and even). I had a look at the TikZ package but I have no idea how to apply & place it on a page or inside a page header.
Any help is appreciated.
This would be a design of a title page including the company details on the right and a logo on the upper right.
This is a design of a default even/odd page having a header including the blue line and the document title.
