I customized the header area of a page with Elements -> Legacy Hooks -> before Header Content with 5 grid-containers (15%, 15% 40% 15% 15%) and 5 Html-widgets for the content of the grid-containers … and the subtitle of the page, placed in the middle under the 40% container.
15%=picture, 15%=text, 40%=picture, 15%=text, 15%=picture. Header and Header-Content = defined at full width.
It looks OK with a normal page.
Testing a 404 Link, the header looks different (pictures left and right are outside the window and the subtitle is no more centered and parted into two peaces (a part slipped away to the right side).
Is it possible (with a filter, like the changing of the headline and text, perhaps – or by using CSS-code) to force the 404 page to use the customized header as it appears with the normal content pages?
