It is the default value. For setting list item marker to a circle we used the circle, for setting it to be square we set the value square. If we set the value none, list items will not be marked.

Solution: If we want to display the list horizontally we can use display:inline or float:left. It will create a menu. E.g. ul {list-style-type: none; padding:0; overflow:hidden; } li {float:left} li g{ display: block; color:red; padding: 20px;}.

Solution: There are two functions for specifying counters, ‘counter()’ or ‘counter()’. First one has two forms ‘counter(name,style)’ and ‘counter(name)’. The second one also has two forms ‘counter(name,string,style)’ and ‘counter(name,string)’.
