Just for a simple example. Take a standard Celtic Trinity Knot. I want the top (like the black plane in the red/black picture) to be a plane in the shape of a trinity knot. The bottom plane (like the red plane in the red/black picture) should be the same shape but with an extra "thickness". I need this to be a volume so I need the planes connected with side walls. The blue picture is a basic volume made of this shape. In the red and black picture it shows the different sizes of the two planes that I need. I can make the blue picture's volume but I need to know how to make one of the sides slightly "bigger" or "thicker" like shown in the red and black picture. In the red/black picture the planes are overlapped to show how the red plane is "bigger/thicker".

1$\begingroup$ So do you want a red border like Harry's solution? Or do you want the shape to "grow" from front to back plane? $\endgroup$– Gordon BrinkmannJan 26 at 8:28

$\begingroup$ I need it to "grow" from front to back. The colors were just to differentiate the back from the front. $\endgroup$– user161472Jan 27 at 17:45

$\begingroup$ Then you can take Harry's answer, select the outlining edges of the extrusion at the front faces, then hit X and choose Dissolve Edges. $\endgroup$– Gordon BrinkmannJan 27 at 18:28

Select the faces along the outer and inner perimeters and press Alt+E > Extrude Faces Along Normals
While you are extruding and moving the mouse inwards, hold down Alt so you get an Even Thickness. Then click to confirm. While the new faces are highlighted, press Ctrl+Numpad+ to increase the selection and Assign the red material to it.
Here's the final result:
