Responsive Web Design Principles: Make an Image Responsive - No Wider than Original Width?

HTML-CSS

The lesson’s text reads as follows:

The max-width property of 100% scales the image to fit the width of its container, but the image won’t stretch wider than its original width.

Is this correct? When I adjust the size of the output display, the image would stretch far beyond its base 250 px width.

It seems to me that this CSS code adjusts the image to be 100% of the display port with no regard for the images original width.

Nevermind. I had it set to width = 100%, rather than max-width!
