Problem:
How to customize / modify / change the background color of the line i’m working on in sublime text 3?
Caveat:
Each Color-Scheme is independent. If you modify, then change schemes, you will ahve to modify again.
Solution:
Preferences > Cusomize Color Scheme >
In the globals section, add "line_highlight": "#color", where #color is the hexadecimal color of your choice.
Example:
"globals":
{
"line_highlight": "#155199",
},
as always, Good Luck!
