电脑网站怎么制作电子商务网站建设案例

在逛掘金时，掘金用户在B站看到的灵感进行的一个卸载窗口的动画效果的实用案例。人类是一种不断在学习的动物，并且是一种模仿能力学习能里比较强的动物。我这里是第三波的学习实践者咯！

相对VUE构建动画效果窗口，我更加喜欢用python来进行实现可爱卸载动画效果。其实，类似的软件卸载窗口，我们可以在一些常用的软件平台上进行看到，他们做的会更加的精美，同时在操作的过程当中也会流畅和丝滑太多。软件在用户在体验过程中进行最后的一次挽留用户的一次机会。

我们自己做的过程当中更多的是对功能的一个实现以及在实现过程当中的学习拓展，搞定后的满满的成就感。我们始终在孜孜不倦，同时又在乐此不疲。希望能够在不同的维度上为你带来一些灵感。
