Width of input type=text element

Question

How come when I do this:

Answer 1

The visible width of an element is width + padding + border + outline, so it seems that you are forgetting about the border on the input element. That is, to say, that the default border width for an input element on most (some?) browsers is actually calculated as 2px, not one. Hence your input is appearing as 2px wider. Try explicitly setting the border-width on the input, or making your div wider.
