> For example, it feels nice to define margin or padding on a <p> element, but what does that mean - distance between two paragraphs? Between paragraph and heading? Between paragraph and bulleted list? Using spacers seems like the only way out of this madness. I don't want to be rude but you are completely misunderstanding what CSS and HTML are supposed to do. 1) The <p> tag denotes that the content in the element is a paragraph in the document. 2) The styling is just tell the client (which is typically a browser) how the element is supposed to be styled. It isn't supposed to mean anything in relation to other elements and it isn't supposed to convey meaning. Generally wherever possible you should try to separate the markup and its styling. You can't always do that, but you should try to.
