In the medium term, any changes should be made to the Sega Retro variant first, before manually copying the contents back here. As this is not an automatic process, this version of the template might also be out of date.

Template to draw a line.

This isn't an intelligent, HTML5/Javascript/whatever line where you define two points and line is drawn between them, because that method is incompatible with wikicode. This is an html span block of height 0 with a 1px border being rotated with CSS. Therefore:

| x1=
| y1=
| w=
| angle=
| colour=
| dashed=
| thickness=
