Change the size of an Embed LinkedIn post

Hello everyone
I want the embed LinkedIn post to be the same size as the rest of the website content, but I can’t get it to fit properly due to any settings.
The rest of the content has a margin of 221,578 px and the embed code from LinkedIn would be as follows:

<iframe src="" height="399" width="710" frameborder="0" allowfullscreen="" title="Eingebetteter Beitrag"></iframe>

Here is my public share link:Link
