top half image of a page stays fixed
you mean just the top half of a page?
so maybe u can create a row.
for example its the first row in your layout
then right click it,
choose "set custom row height"
enter: 50svh
put something inside the row
In the gridder, right click on the row and choose "set html class and id". For "html class" enter: fixedrow
Enter the custom css in "lay options" -> "custom css & html":
.fixedrow{ position: sticky; top: 0; }maybe u need this instead:
.fixedrow{ position: sticky; top: 0; z-index: 20; }not sure
