The Letter E Posted December 5, 2010 Share Posted December 5, 2010 As far as I know you CANNOT use a half pixel UNLESS you are styling a text element... GOOD EXAMPLE: #myDiv { font-size: 12.5px; } BAD EXAMPLE: #myDiv { width: 350.5px; } I think the common misunderstanding is that a pixel is some relative form of measurement. A pixel is a standardized unit and the smallest usable screen element. A pixel contains only one solid color created by mixing light intensities such as red, green, and blue(RGB), or cyan, magenta, yellow, and black(CMYK). I hope this helps a little bit. You can definitely find more in depth info if you keep searching.

SyntaxPro Posted December 7, 2010 Author Share Posted December 7, 2010 I heard of sub pixel rendering, but why if i hit print screen and count that the DIV with text is 13 pixels off from being leveled with the image on its left... why do i have to put 12.5 to level it out... it should be 13 logically... makes no sense Link to comment https://forums.phpfreaks.com/topic/220716-half-pixel/#findComment-1143892 Share on other sites More sharing options...
