'Space between the border of my rotated svg icon and the svg canvas

I'm creating a rudimental web icon system (a kind of sprite) with svg. However in my code around one icon (between the smash magazine icon and the red border) there is some room. I would know how it is possible to remove it. The icon is rotated and with the viewBox I'm not able to do the job. May be I have to make some transformation. How could I do?

Solution 1:[1]

Your SVG's have default display:inline and there's a whitespace between them, which is rendered by browser like it was a whitespace between two words. Quick and dirty solution is to remove the whitespaces - all of them, including line breaks. But the better one is to use flexbox to turn your SVG's to flex elements.
