Hello. I am new to Web design and have started using Ian Lloyd's "Build Your Own Web Site the Right Way" as a guide in my efforts. On the whole, I find the book quite useful, but one thing that I do not understand is why the mark-up examples always show varying degrees of indentation between headings, sub-headings, and so forth. Is this just an aid to viewing in outline form? It doesn't seem to be needed as I have pretty much given up on indenting the lines as given and still obtained the desired results. So why is it conventionally presented this way? Neither the proper way to indent (which apparently involves a complicated style change with long paragraphs) nor the reason for doing this are explained in the book (or in any of the other introductory books I have consulted in seeking an answer to this question). Thanks. --Alan
