描述
Describe the bug When you zoom in on a page that has icons from nes.css on it, the icons begin to show with white grid lines in between them as if the squares used to make them aren't touching anymore.
To Reproduce
- Go to https://nostalgic-css.github.io/NES.css/ and view the icons.
- Zoom in (and out at different percentages) on the browser.
- View icons rendered with gaps.
Expected behavior
Icons should be rendered similar to how they get rendered at 100% zoom.

Environment:
- OS: Mac
- Browser: Chrome
- Build environment (i.e. NodeJS): N/A
Suggestion(s) for fixing this issue Unfortunately I don't know much about rendering graphic
Additional context Love NES.css!
