效果預(yù)覽

初衷：很多人在初學(xué)前端的時(shí)候都會(huì)問，“如何入門前端？”
同為在前端學(xué)習(xí)道路上，奮力追趕的一員，本人對(duì)于目前網(wǎng)絡(luò)上所能看到的 “入門級(jí)” 的教材并不太滿意。學(xué)習(xí)一門新知識(shí)，實(shí)例是尤其重要的。在這里本人整理了目前頁面上常見功能實(shí)現(xiàn)的具體實(shí)例。愿能為大家提供一些幫助。
希望能夠與大家互相分享，共同進(jìn)步。

好啦，現(xiàn)在所有的代碼都寫完啦！

趕快打開瀏覽器，看看效果吧！

在這里，只是給大家提供一種思路，參考。
具體的實(shí)現(xiàn)，每個(gè)人都可以有不同的方法。
請(qǐng)大家趕快發(fā)揮想象，把你最想實(shí)現(xiàn)的功能，在電腦敲出來吧！
