They always have a fixed physical size. Main absolute units: | Unit | Meaning | Size | |---|---|---| | `px` | pixel | the smallest point on the screen (conceptual, but fixed for CSS) | | `cm` | centimeter | 1 cm | | `mm` | millimeter | 1 mm | | `in` | inch | 1in = 2.54 cm | | `pt` | point | 1pt = 1/72 inch | | `pc` | pica | 1pc = 12pt | --- ### Key point Although there are formally many absolute units, **in real-world layout almost only** `px` **is used**. The rest (cm, mm, in, pt, pc) are better suited to print or PDF, not interfaces. --- In short: absolute units give a fixed size, but are mainly suitable where responsiveness does not matter. On the web they are used sparingly, with relative units (`em`, `rem`, `%`, `vw`, `vh`) usually preferred instead.For the reviewerNote to the moderator (optional)Visible only to the moderator.
