I have found that my CSS rules for the tour element behave differently when using HTML5 vs. Flash. I would like to be able to use CSS to create alternate layouts for a page that may have different sizes for the pano.
When using embedPano with Flash, if you don't specify a height or width swfkrpano will default to 100%. However, since these values are set on the width and height attributes of the embed tag I can override theses values with CSS.
But if you are using HTML5, the default width and height are set on the style attribute, overriding my external CSS.
I'm sure I can find a way to work around this, but it does make things a little bit more difficult.
