How can I delete this pulldown and not affect the appearance of the jukebox?

When I attempt to delete these pulldowns, the styling of the jukebox / player changes and I don't know why. How can I get rid of the pulldowns and not affect the player.

When I say, "the styling of the jukebox / player changes," I'm referring to the background of the player itself. It goes from black to this:

You can see what I'm talking about by heading out to http://brucegust.com/mysingingvalentine/demo/sandbox.html

There's a systemic connection between the top two pulldowns and the player itself and I don't know what.

Bottom line: I want to get rid of the pulldowns. How?

Here's the page: http://brucegust.com/mysingingvalentine/demo/sandbox.html

Here's the way it looks like when you remove the pulldowns:


If I try to delete this section:

 <section>
            <h3>Global Options</h3>
            <form action="#" method="get">
             
                <label>Stretching (Video Only)<select name="stretching">
                    <option value="auto" selected>Auto (default)</option>
                    <option value="responsive">Responsive</option>
                    <option value="fill" selected>Fill</option>
                    <option value="none" selected>None (original dimensions)</option>
                </select>
                </label>
            </form>
        </section>

I get the change in the appearance of the jukebox. How do I accomplish my changes with the page in general by deleting that syntax and NOT affect the color of the player?

Thanks!
