Skype Web Browser Plug-in Causes Web Designer Headaches
I recently looked at a web site I had designed many years ago, KellersKove.com, and realized that the Skype browser plugin that Skype automatically installs had changed (broken) the page layout inserting its own CSS in to the web page via the Skype plugin.
Here is what you will have to do to fix it.
You will have to upgrade the Doc Type to:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
Add a Meta tag to the head section of your web page:
<meta name="SKYPE_TOOLBAR" content="SKYPE_TOOLBAR_PARSER_COMPATIBLE" />
I added it to my broken web page and it worked. Skype knows what they did. You can read some of the complaints and feedback here.
