HTML does its best to accommodate whatever circumstances it finds itself in. Vary the size and proportions of your browser window right now. Make it small, then skinny and tall.
You can see how the text in this window will rearrange itself to accommodate the size and shape of the browser window. The text "flows" inside the browser window. By default, text and images will just rearrange themselves to be seen. They will maintain the linear sequence in which they were originally placed, but creating virtual line breaks as dictated by the browser's shape and size.
