Each time that a link or button triggers the mandatory opening of a new window in the browser, the user must be forewarned:
For example:
<a href="cgv.html" target="_blank">General terms and conditions (new window)</a> <a href="cgv.html" target="_blank"> General terms and conditions <img src="images/new-window-pictogram.png" alt="(new window)" title="(new window)" /> </a> <a href="cgv.html" target="_blank" title="General terms and conditions (new window)">General terms and conditions</a>
Do not apply this recommendation on links or buttons opening modal windows.
