在无序列表ul>li中，无线列表的标志是出现在各列表前面的圆点。在有序列表ol>li中，前面默认带有数字，如何修改列表前面的项目符号，只需要通过list-style调整就好，常见的符号有（/*内容注释部分*/）list-style-type:circle;/*空心圆*/list-style:none;/*去除标志*/list-style:square;/*方块*/list-style:upper-roman;/*罗马数字*/list-style:lower-alpha;/*list-style-type:upper-alpha;大写字母*/list-style-type: decimal;/*序号数字展示*/等！
