animation - how to animate .jpg image with CSS? -

i'm trying animate image, i.e. move left right , before implementing css animation keyframes noticed cannot element in html obey css style - whatever style changes create in css, image on webpage remains same size, in same place, etc.

html:

<div id="animate"><img class="thumbnail" src="flower.jpg"> </div>

css:

#animate { width:200x; height:100px; }

you need select img:

img { width: 200x; height: 100px; }

css animation
