Hi Saber:
You can do this directly in symbology. See link below, Use Rule Based
Symbology and "Elev" % 100= 0 to separate all the contours that are
multiples of 100. Set your line symbols and you should be good to go.

Hi Azzurra,
You can use Raster styling to display it as contours with minor and
major contours:

Hi to all,
I have extracted contours from a dtm raster 20 m resolution file
and the result is a vector file of contours with 20 m of interval
between the contours.
I would like to have two different symbols for these contours: for
example black colour and thickness 1 for the contours with
interval of 100 m (0, 100, 200, 300 etc.) and grey colour and
thickness 0.5 for the contours 20, 40, 60, 80, 120, 140 .. etc.).
What can I do?
Normally I create another contours file only for the contours
equidistant 100 m and I put a different symbol for the 2 layers.
Do you know other ways without the creation of another file?
maybe rule-based symbology?
Thank you, Azzurra
