Inventor of pixel

The page for Russell Kirsch credits him as the "inventor of the pixel," yet he does not appear in this article, and the term is credited here to others, so either this page is incomplete or the other page is wrongly attributing the invention to him. — Preceding unsigned comment added by 71.198.178.65 (talk) 00:31, 14 August 2020 (UTC)

Pixel as unit of measurement

The article currently states this: "Pixels, abbreviated as "px", are also a unit of measurement commonly used in graphic and web design, equivalent to roughly 1⁄96 inch (0.26 mm). This measurement is used to make sure a given element will display as the same size no matter what screen resolution views it," and quotes this article about CSS from W3C as a source.

I believe the source is wrongly interpreted. Px as an equivalent to 1⁄96 inch is only true in case of printing of CSS styled document. The linked article clearly states that px is "...usually not related to physical centimeters or inches..." It also doesn't make sense to claim px measurement would be used to make sure given element is the same size no matter what screen resolution is being used to display it. Logically, 100x100px square will have drastically different size when displayed on old 1280*720 21" screen and on latest iPhone. In reality, px measurement is used to make sure the element at least 1px wide is always visible (it is not narrower than available resolution) and that element with dimension set by integer in px has always sharp edges. This is also mentioned in the quoted source. Delltar (talk) 09:57, 5 October 2021 (UTC)
