To make links in a web page to open in a target frame or new window all you need is to add target=”_blank” in between the <a href=”***”> section of the html code, where *** is the default target frame.
target=”_blank” Opens a page in new window
target=”_self” Opens a page in the same frame
target=”_top” Opens a page in the top page breaking all frames
target=”_parent” Opens a page in parent frame
We can also use target=”frame or iframe’s name” to make the link to open in that frame or iframe.
To make links to open in a target frame or new window by default add <base target=”***”> in between the <head> section of the code. This also works for Blogger’s templates, for Blogger Beta’s templates since it had to be XML compliant you have to add the closing tag </base> at the end to <base target=”***”> to make it work.
