But how can I generate the SVG code? I have an SVG image.
This isn’t a theme-specific question so I’d recommend Googling for some instructions.
Also, doing this will also improve my pagespeed
I don’t think you will see a difference there but not sure either.
and after doing this I have to remove the current logo from the customizer?
Yes
Lastly, what about the height and width of the SVG logo?
Might need some CSS tweak but can you add the logo in first?
