I can reproduce this as well, in Chrome, (although you masked the problem by adding style="display:none;"
to your script tag which is why no one else is seeing this). My google translate extension showed the problem as well:
Your issue is in style.css where you have this rule:
* {
...
display: block;
...
}
You need to change that selector to be body *
otherwise it will apply to literally everything on the page.
As others have mentioned you have an unclosed PHP tag (on a non-PHP page, natch), but that's not the issue here.
Also, that extra >
on the page is not from a script but you have an extra > on the line:
<font class>>
