I tested the simile timeline menu on the left in Safari, but since I haven’t spent much time on it yet, I forgot to test IE and Firefox – with embarrassing results, it didn’t work at all as I learned today.
It quickly turned out that the problem was in the following two lines:
... <script src="/wp-content/themes/boc/timeline-api.js" type="text/javascript"/> <script type="text/javascript"> ...
I was naive enough to expect that any decent browser wouldn’t have any problems with the first line, but it turned out that IE and Firefox DID NOT process the “/>” at the end of the first line. To be more precise, the javascript that followed the second line has not been processed at all, because the browsers were confused by the end of the first line.
When I changed it to
... <script src="/wp-content/themes/boc/timeline-api.js" type="text/javascript"></script> <script type="text/javascript"> ...
everything worked fine. To be honest, I don’t understand why. If anyone can explain me the background of this behaviour – please leave a comment.
BTW: Safari worked as expected.
