Hide the Iframe scrollbars but still can scroll - html

Question

Actually, I know that this question has been a lot even just in stackoverflow, but still, the answers I found does not work for me - lots of them are asked long ago. But however, I'm trying to put an iframe inside a web page, and it's from the same origin. The problem is, every time I scroll, these annoying scrollbars came out. I've tried to make changes like adding overflow: hidden (which makes it worse - it disables scrolling!), scrolling="no" (same as overflow, disables scrolling), and more. Is there a simple way that I can remove the scrollbar on the iframe but still can scroll it? CSS are better, but if it can be done in JavaScript at someways, it's also OK. Thanks a lot!!
Update: My code:
the parent page: (things in {%%} and {{}} are jinja templates, I use them to render the template)

And my web page in the iframe:

Answer 1

Kind of a hacky solution, but this will hide the scrollbars by making the frame bigger than the container.
.outer {
width: 500px;
height: 150px;
overflow: hidden;
}
.outer iframe {
width: 520px;
height: 170px;
overflow: auto;
}
<div class="outer">
<iframe src="/"></iframe>
</div>
