html iframe is too small

on my home page I added a html iframe code and it is appearing too small.  its a search for properties for sale.  I think it has to do with coding:

<iframe  width="100%" height="100%" frameborder="0" marginwidth="0" marginheight="0"></iframe>

Can you share link to your site? 

you used with=100%, height=100%

You need to increase the size of the parent element

@guardianrealestate254 /config/pages is admin url

Your site is private. Setup password & share url.

Your site is prviate

That is your site?

You need to use custom code to increase the size of the parent element, or try to edit 100% with any number, for example width = "900"

So, you should share your site url to check code.

What is access password? @guardianrealestate254

try this code

div#block-yui_3_17_2_1_1572567603013_10718 iframe {
    height: 600px;
}

Keep the code and i will check

Add my code to HOME > DESIGN > CUSTOM CSS
