How Do I Get My Website To Scale Down To A Mobile Device?

I can see there are 2 meta tag declared in the html document

1.
<meta name="viewport" content="width=720">

2.
<meta name="viewport" content="width=device-width; initial-scale=1.0;">

first one is in the head and second one is in the body. Ideally your second one should have been in the head tag. Meta tag is body is ignored as per below post.

Try changing if it helps.
