To optimize your URL keywords, always use a hyphen (-) between words in your weblinks. Google recognizes hyphens as spaces, but not underscores. Slashes (/) are also treated as spaces, but they are not recommended for URLs. However, you can use slashes to separate keywords in your texts.
To avoid inconsistencies across different browsers, always use the following CSS code unless you specify a different value for padding and margin. Some browsers do not set these properties to zero by default. html { padding: 0px; margin: 0px; } body { padding: 0px; margin: 0px; }
never use position:absolute; left:99px; its a handy little quick fix to position an element but it doesn’t ever work.
