This time I will show you how to operate the unordered list attribute in JS, and what are the precautions for operating the unordered list attribute in JS. The following is a practical case, let's take a look.

list-style-type##     none: No mark. disc: solid circle (default). circle: hollow circle.

square: solid square. decimal: number.

                               

list-style-position

    inside number or grid style is inside li and occupies The width of li

The outside is outside the li and does not occupy the width of li

                                                           tle ui LI ’ and does not occupy the    of li’s width

    (3) list-style- image Use images to replace the tags of list items
