responsive – fills container automatically to aspect ratio
fixed-height – keeps the specified height unchanged
fill – fills available height & width
container – lets its children define its size, like a normal div
flex-item – works like display:flex style
intrinsic – responsive until it reaches its height and width

p{font-size: 0.9em;}

<amp-img
media="(min-width: 720px)"
src="demo.jpg"
width=300

</amp-img>
</amp-anim>
