In some pages there is a space in between the header and the pages. I know that when you create a custom page it is like that but it doesn't look nice and a little bit messy....
Is there a way to make it fit the rest off the pages and remove the space and text in between?
Thanks

It can be usually adjusted via margin.
Each page should also have unique ID or class on body.

@MB Themes,

With element inspector it shows that the space is <div class="breadcrumb"> Since hiding breadcrumbs in admin is there, isn't it possible to hide it there (maybe?) I tried but i do not understand the correct setting for that.
It says: Enter custom pages where to hide breadcrumbs, i.e. for plugin pages, in format: location-section. Delimit with comma (,). Example: osp-cart, osp-promote, blg-home
In my case this would be oc-content,plugins,user_rating,index 

@mwindey
body#body-custom should do the job to identify

@MB Themes,
Thanks but it did not work... I found the solution with google and was able to solve in the meantime 
Solution was simple....
In style from theme:
body#body-user-custom .breadcrumb {display: none;}
Thanks for your help!

EDIT:
Your solution also works! It was because of my skills it didn't work LOL 
Again thank you for helping!
