同学你好，解答如下：
1、整体效果是可以的。如果再完善一下五角星的形状会更好。例如：
.star1 { position: absolute; width: 0; height: 0; top: 60px; border-left: 100px solid transparent; border-right: 100px solid transparent; border-bottom: 80px solid yellow; transform: rotate(35deg) scale(0.5); } .star1::before { content: ""; position: absolute; left: -100px; top: 0; width: 0; height: 0; border-left: 100px solid transparent; border-right: 100px solid transparent; border-bottom: 80px solid yellow; transform: rotate(-70deg); } .star1::after { content: ""; position: absolute; left: -63px; top: -47px; width: 0; height: 0; border-left: 30px solid transparent; border-right: 30px solid transparent; border-bottom: 80px solid yellow; transform: rotate(-35deg); }2、编程题是没有完整代码的，因为代码很灵活，实现的方式不是唯一的。在学习阶段 , 鼓励大家先独立思考并完成效果 。做完之后存在疑惑的 ,可以在问答区域提问 ，老师会针对你的代码进行指导 , 这样能够了解同学具体哪里掌握的不好 ,有针对性的为你指导 。同学也能通过老师的指导，锻炼自己独立思考与编码的能力，才能更好的帮助你去成长 。
祝学习愉快~
