【每日一练】27—CSS实现留言板效果_留言板

作者 | 杨小爱

留言板在我们的很多项目中都会用到，这个设计的目的就是收取目标用户的信息，以便我们及时与用户取得链接，解决用户的问题，然后实现其作用与价值。

因此，今天我们练习一个简单留言表单的实现，具体效果，可以看下面的截图：

【每日一练】27—CSS实现留言板效果_html_02

在今天这个小练习项目中，我们没有使用到什么复杂的图片素材，只是用到了几个简单的ICON图标，这些图标均来源于阿里巴巴矢量图库，如果需要的话，大家可以自行区下载获取即可，ICON图标地址：https://www.iconfont.cn/，我这里就不再上传这几个ICON的图标素材了。

接下来，我们就一起来看看代码实现过程，建议初学者还是多练习，也许你会觉得在做重复的事情，但是在没有学会之前，我们就只能这样做了。
