Yes it is possible with CSS to have links open in new tabs or new windows. I discovered this issue when testing target="_blank" in IE9/IE10 versus Chrome.
<a href="[yourlink]" target="_blank" style="target-new: tab;">GetPowers</a> Or you could put it in the header as:
<html>
<head>
<style>
a { target-new:tab; }
</style>
</head>
<body> There are some options for the target-new style:
target-new: window | tab | none
