about size/resize, and measurements: when assigning width or height, px is often! how many px's are there per inch or per cm? for width, it is convenient, with some other measurements applicable, but for height? px's is rather imperceptible! I tried to attribute a certain height in my code, what is best: px, rows, number of lines or what?
