今日任务：对电影详情界面进行优化，主要完成了“星级评分”模块，使界面可以根据电影评分的不同而产生不同的星数。
星级评分模块主要代码：
1 <div class="score">
2 <p class="star">豆瓣评分：<font size="5" face="arial" color="black">9.7</font></p>
3 <canvas width="250" height="20" id="D_myCanvas"></canvas>
4 <p class="star">腾讯视频评分：<font size="5" face="arial" color="black">8.5</font></p>
5 <canvas width="250" height="20" id="T_myCanvas"></canvas>
6 <p class="star">爱奇艺评分：<font size="5" face="arial" color="black">6.0</font></p>
7 <canvas width="250" height="20" id="A_myCanvas"></canvas>
8 <p class="star">IMDB评分：<font size="5" face="arial" color="black">7.5</font></p>
