# Safari 1.0 PRE width bug

As noted in my blog, in certain cases Safari will miscalculate the width of a PRE element. I think I've found the trigger. If a nested container element is preceded by uncontained text and a blank line, and there are "too many" characters contained in the nested element, the PRE width will be too wide. In the examples below, the nested element is a SPAN whose content is the days-of-week line, as follows:

        <SPAN CLASS=dow> D  M  T  W  J  F  S</SPAN>

## Example 1

            2003

     D  M  T  W  J  F  S

          September
        1  2  3  4  5  6
     7  8  9 10 11 12 13
    14 15 16 17 18 19 20
    21 22 23 24 25 26 27
    28 29 30
| The blank line between '2003' and the nested element triggers the width bug.

## Example 2

            2003

     D  M  TWJFS

          September
        1  2  3  4  5  6
     7  8  9 10 11 12 13
    14 15 16 17 18 19 20
    21 22 23 24 25 26 27
    28 29 30
| The blank line between '2003' and the nested element triggers the width bug. Here, the excess whitespace is reduced by reducing the number of characters contained by the nested element.

## Example 3

            2003
     D  M  T  W  J  F  S

          September
        1  2  3  4  5  6
     7  8  9 10 11 12 13
    14 15 16 17 18 19 20
    21 22 23 24 25 26 27
    28 29 30
| The blank line between '2003' and the nested element has been removed, so the bug is not triggered.

## Example 4

            2003

     D  M  T  W  J  F  S

          September
        1  2  3  4  5  6
     7  8  9 10 11 12 13
    14 15 16 17 18 19 20
    21 22 23 24 25 26 27
    28 29 30
| The blank line between '2003' and the nested element no longer triggers the width bug, because now the '2003' is itself contained by a nested element (in this case, another SPAN).
