Horizontal rules are a great help in separating sections of a page, but they are not a panacea. Don't leave unimplemented links If you don't have a file or script to link to, don't implement it. Also, check your links occasionally to see if they still exist. If they don't, remove your reference to them. Check for spelling and grammar errors .
Restraint is suggested for punctuation and for varying fonts.
Consider using exclamation points and question marks sparingly. The same goes for ellipses and dashes. Consider people with systems and browsers different from yours . Some don't even move forward and backward between links easily, or, for that matter, caches them. Consider putting links in various directions at the bottom of your pages, whether as icons or straight text.
