I want to make a rectangle using 4 straight lines

Sorry I’m Japanese so, I’m nonnative.
I want to make a rectangle using 4 straight lines (thickness 3px).
I adjusted the length of the line and the margins from the top, bottom, left, and right so that it becomes a rectangle.
However, the lines do not overlap well and it is not possible to make a beautiful rectangle.
What settings should I make to make a rectangle?
The size of the section is vh = 100 (and vw = 100).

@mamorous3578-af1 why won’t you use container with transparent or white background and borders set to 3px? here is the example:

Mr. Andrew Taran . Thanks for your reply !

@mamorous3578-af1 I also recommend using a container with a border as I find the less elements you need to recreate the design, the easier it is to work. But I was able to see that if using a horizontal line that is less than 5 pixels in width, it seems to want to docking is lining up to the selection tool and not the line itself.

If you’re using 3 pixels in width, you can try using -2 pixels of margin to get it to line up correctly. I made a video as well below so you can see.

Wao!Amazing!
Mr. Roberto Rocha , thanks for your reply.
