Custom full width code for image not working properly

Hello!

I added a custom “HTML Embed” code to show the following:
http://diegocardenas.co/launch/

I copied and pasted the index.html to the HTML Embed but the following shows:
http://ignited.webflow.io/

For some reason, in the original I have an image the covers the whole height and width but in Webflow it only covers the full height. I tried manually configuring the width and height via the Webflow panel but that didn’t work. You can see what I mean if you play with the browser height and the image does not cover the whole width.

Any help is appreciated!
