About px and % (1200px base)
px and % (1200px base) are common css measurements.
💡 Did you know?
CSS percentage widths are relative to the containing block, not the viewport. A 50% div inside a 600px container is 300px, not half the screen. Only viewport-relative units (vw, vh) are relative to screen. This is the most common CSS misunderstanding among new developers.
