网站加地图百度网站回档怎么能恢复

巧妇难为无米之炊，想写功能但是没有好看的设计，边写边设计效率又不够高。mastergoAi生成的页面又不够好看，而且每月给的免费积分用得又超快，so决定自给自足。能有多难，先做，做了再改。

于是决定踏足设计，本期话题新手如何用mastergo设计小程序页面。

先去小红书上找找模子，看能否复原。摸了一晚上，感觉效果还行，比ai生成的要好看那么一点。只是想画个时钟出来不知道怎么画好，还的看怎么用canvas实现时钟动画。

附上mastergo网址：MasterGo 莫高设计 - AI 时代的数字界面生产平台

有了UI页面画起来就是快多了

今天用canvas绘制了时钟，然后调整了下整体的布局更简洁直观了

另外再附上canvas绘制时钟代码，canvas越写越有意思了
