iFrame удаляет div

У меня есть небольшая проблема: когда я использую iFrame, он удаляет div. Я думаю, что ошибка находится где-то здесь:

<h1>About</h1>

<iframe src="http://www.wikipedia.com" scrolling="no" width="960" height="500" frameborder="0" style="margin-left: 0px";>

<div class="center">
    <p style="text-align: justify; ">&nbsp;</p>
<p style="line-height: normal; font-family: Verdana; "><span style="letter-spacing: 0.0px">People are extremely visual creatures. That is why very few things can beat the power of moving imagery and that is primarily why we got involved in creating them.&nbsp;</span></p>

<p style="line-height: normal; font-family: Verdana; "><span style="letter-spacing: 0.0px">REDRUM started as a creative film and animation studio in 2009. Like the enthusiastic filmmakers that we are, we try to tell memorable visual stories that help our clients get their message across. We believe that having each discipline involved in the process work under one roof, creates a strong unity and achieves even better results. From concepting&nbsp;to final product. Talented people with different skills can learn and grow from each other in a collaborative atmosphere. Its how we like to do things, and we trust that it shows in our work. </span></p>

<p style="line-height: normal; font-family: Verdana; "><span style="letter-spacing: 0.0px">But dont just take our word for it; come see for yourself. Join us at our studio for a good cup of Italian&nbsp;coffee and a round of pool.</span></p>

</div>

Кто-нибудь есть идея, что может вызвать это? Я тестировал его, и он отображает весь текст без iframe, но когда я добавляю его, весь текст уходит.
