If you want to overwrite any other pages or blogs displaying your blog or website pages in their frames, you might like to use the Break Out of Frame script as given below (inside the header section).
<!– Break out of frame –>
<script>
if (window!= top)
top.location.href=location.href
</script>
But be aware that if it’s you customizing any blogspot blog template never user such script simple becuase this destroyes your drag and drop layout of your blog setting. Add new element is totally lost. And further your layout section breaks out to maximize, without letting you the option of Tabs.
This is what I faced up while customizing with my present template Denim by Darren Delaye.
