You can either use an anchor tag and style it

<a class="btn btn-success" href="https://www.google.com" target="_blank">Google</a>

Or you can change your button to

<button title="button title" class="action primary tocart" onclick=" window.open('http://www.google.com', '_blank'); return false;">Google</button>

<button type="button" onclick="window.open('http://www.website.com/page')"> button</button>

Im trying to create a button that links to a PDF file open in a new window.
Tried the _blank method but that didn’t work.

<button onClick="parent.location='files/sample.pdf'" class="send" >Curriculum vitae</button>
</form>
