Why does SVG code offset html blocks?

Question

css

The moment when I refreshed the page after adding the code turned out to be very unexpected and saw that the blocks had shifted down (well, or a place was added at the bottom if you paste the code at the end). In another layout, this problem did not arise. The code itself (pug)

svg(width="0" height="0")
      defs
        symbol#i-close-svg
          path(d="M64 0L0 64l448 448L2 958l64 64 446-446 446 446 64-64-446-446 448-448-64-64-448 448z")

Answer 1

svg is a block element itself. And if the width itself is not specified in it, it occupies the entire area
