Sizing of SVG images

Hi,

I'm trying to insert a few SVG images into my dreamweaver page and no matter what the width and height values are the images always fill the entire width of the parent container. I can't get them to render at the size I've saved them at in Illustrator. I've tried adding a class to them with the max-width attribute, and that didn't work. I wrapped the images in a div container and attached a class to that, with a max-width attribute, and that didn't work either.

If I have a svg image that measures 400px x 100px, how can I get it to render at that same size on the page? 

Thanks for any help you can provide.

Kind regards,

Mark
