Typeform page embedding

I am trying to embed the typeform that i created as a full page embedding however it doesn’t seem to work. The website is medx.manmedsoc.com and the code that i was provided is below. Where am i meant to place this code for the whole page to have the typeform. I also have a custom css if this would make it easier?

<!–Add the title of your typeform below–>
<title>Register Your Interest</title>

<!–CSS styles that ensure your typeform takes up all the available screen space (DO NOT EDIT!)–>
<style type=“text/css”>

}
