The only way I know to make an image re-size with the window is to use percent rather than pixels when setting the image size, but the default in the SS editor is pixels. Assigning a class to img in the css so that whenever the class is called the image size will be a set percentage will work, but I'm not sure if this is best approach. Am I being lazy and choosing the easiest option or should I be looking to set a default in the php?
In my mind php should be used to define the foundation or structure of the site rather than the styling, yet it can be easily used to output content to a set style. (font color is the first example that comes to mind, though I would imagine it wouldn't be hard to set an image size) Is one better than the other or am I just thinking like a designer rather than a developer?
