CSS Question

Bootstrap modal not filling up space properly

This is more of a general question than anything. So I have two situations. One where I create an iframe inside the modal and the other, I fill the modal via an Ajax call.

The problem with the first situation is that the iframe is very small compared to the overall modal, filling up only the left side of the modal.

small iframe

The problem with the other method is that it may sometime create lots of empty white spaces.

white space

I was wondering how to get around these two issues. I've tried overriding it with

max-width: 100%; width: auto; height: auto
but they didn't do anything besides stretch it to max by default.

Bonus:
I find that Bootstrap modals are too convoluted to be used in a more complex manner. If anyone could recommend me a better modal system that would be great. I've used jQueryMobile before and their modals were excellent (as they fixed the spacing issues), however they came with problems of their own.

Answer

Changed CSS Properties to make this happen as the popup with consider based on the content inside the body.

.modal-dialog{max-width:800px; width:auto !important; display:table}
<link href="http://getbootstrap.com/dist/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://getbootstrap.com/dist/js/bootstrap.min.js"></script>

Modal with limited text 
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch Modal
</button>

Modal with Large Content
<!-- Large modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#bs-example-modal-lg">Launch Modal</button>
