I flagged your post as it is in breach of the forum rules at FAQ - Manager Forum under section Be specific
If your question is related to custom themes or custom reports, always post the code or report definition you have developed and the results it produces. Do not simply post a picture of something you want and ask other users to tell you how to achieve it.
There are 2 issues:
Custom themes are put in obsolete features so it may disappear one day and any effort to create new ones will be lost. Furthermore some functions such as Footers do not work with custom themes.
You need to show your own attempt to develop a custom theme and explain where you are failing.
