块之间有空格

解决办法
如果多个span连续编写,像这样: <span>连续的span</span><span>连续的span</span>
是不会有空格的 但是真正开发代码的时候,一般不会连续书写span,而是不同的span之间有回车换行,比如这样: <span>有换行的span</span> <span>有换行的span</span> <span>有换行的span</span>
而这样编写代码,就会导致<span>之间出现空格

使用float来解决。 float使用完毕之后,记得在下面加上 <div style="clear:both"></div> 用于使得后续的元素,不会和这些span重复在一起

代码高亮插件双击即可选中,不过部分同学反应,通过代码高亮插件复制的代码无法在IDEA里正常显示,这里提供TEXTAREA的方式,方便复制,谢谢
1. 自行完成练习
根据练习目标尽量自己实现代码效果,期间会碰到疑问,难题,和自己不懂的地方,这些都是必要的过程
2. 带着疑问查看答案
完成过程中,碰到无法解决的问题,带着疑问,查看答案,分析答案的解决思路
3. 查看答案讲解视频
依然有不明白的地方,点开视频讲解,带着疑问,听视频讲解有问题的部分
4. 再做一遍
理解后,再从头做一遍,把有疑问的地方都捋清楚
5. 总结
最后再总结一遍,总结思路,总结解决办法,以后遇到类似的问题,怎么处理
