Styling script inside of HTML

I'm trying to style a stock widget taken from: http://ift.tt/2fH9VcW. I am using Bootstrap to help style the page.

In order to place it inside of a div, I had to put the script itself inside of the HTML code I've written as shown below:

    <div class="col-md-3 col-sm-12 well">
        <script src="http://ift.tt/2gmtc1N"></script>
    </div>

However, I cannot style the size of the stock which causes it to be bigger than the space I have allocated for it as shown below:

Is there any way for me to edit the size of the script? I have already considered increasing the column size, but that is not an attractive option considering other elements of the page.
