Edit Lines width!

Hello,I am new in JSOM and I want to change width and color of lines(boundaries).I watched some tutorials and guide but I still cant get it.Can someone please help me,and tell me how to do it step by step.

Somebody,please?!!

Thanks in Advance!

If you are talking about the resulting rendered maps, as for example www.openstreetmap.org, you shouldn’t even try to do this. The map describes the logical structure of the world, and it is up to the rendering tool chain to decide on details of how to render it.

If you are talking about how things render in JOSM, I think you need a more JOSM targeted forum, although I would be curious as to the reason for wanting to do this.

You can do a search for “own style” or similar key words on https://help.openstreetmap.org/

there are solutions for your aims to influence rendering like you want.

HI,thanks for response!
I read the documentation and I see I cant change the color!

I am doing this for school project not for an update in maps.
All I want to change is line width!

Is there any tool in JSOM for doing this?
Somebody,please??
