About the Unit
Millimeter (mm): The millimeter (mm) is a physical unit of measurement, 1/10th of a centimeter. Like cm, mm is commonly used in graphic design and printing, where precise physical measurements are needed. In CSS, mm is useful for defining width, height, and other dimensions of elements in layouts that will be printed or converted to other physical formats. Using mm is an effective way to ensure precise and consistent layout dimensions during the printing process. For digital designs, the mm unit may be less practical, as most web interfaces benefit more from relative units to ensure a more adaptive user experience. However, for technical documents or precision graphics, mm may be the best choice.
Pro Tip: mm → vh
Use mm for physical measurements, vh for viewport-based height.
