HTML:
<div class="safe-block">
<strong>Always stay safe!</strong>
<span class="txt">Never pay down a deposit in a bank account until you have met the seller, seen signed a purchase agreement. NO serious private advertisers ask for a down payment before you meet. Receiving an email with an in-scanned ID does not mean that you have identified the sender. You do this on the spot, when you sign a purchase agreement.</span>
</div>
