Embedded Google Doc looking teeeny tiny!

Can anyone give me the code which will make this google doc show up centred and readable on both mobile on desktop?

Ignore the design of the page for now as I'm just testing this out!

I found this code from a previous thread and I changed the width to 100% and that works but it was left aligned.

 

@media screen and (min-width:768px) {
div#block-yui_3_17_2_1_1664290343213_3729 iframe {
    width: 50%;
    left: 50%;
    transform: translateX(-50%);
    height: 3800px;
}
}

Don't remove any code in your current code
