It does not appear in page, but your google account in another window or another tab will get logoff. Now an external website could logout you from your gmail or orkut.

IF you are facing problem with layout issues inside iframe (which is normally not there in normal pages) just test these things.

Posted by Sajith M.R in html on 08. Nov, 2009 | 0 Comments
If you are using mootool and jquery same time in your html pages, it normally won’t work. Because both are using $ variable for the base object. So only the last js file included will be active.

Include jquery js file second
Like this:
<script src=”javascript/mootools-release-1.11.js” type=”text/javascript”></script>
<script src=”javascript/jquery-1.3.2.min.js” type=”text/javascript”></script>
Then [...]
