一、前言🔥
听说全网都在挑战这个,bug菌火急火燎,马不停蹄送来源码教学教程!快拿去送给你喜欢的那个ta吧。废话不多说,咱们先来看看代码运行效果,是不是你们想要的爱心动画?
如上便是李珣同款爱心,代码都帮大家准备好了,接着往下看!
若你中意的那个ta想拥有与全网不一样的爱心,比如如下,DIY文字版特效爱心,代码也帮你们准备好了,你只需要修改文字部分内容即可!不懂代码的也没关系,我会手把手教学,让你就算看不懂代码也能学会自定义文字!真的超级简单。代码教程我都放在下方了。
二、源代码🔥
如下附上该特效核心代码,请查阅,若有完全免动手不想费力的小伙伴,可以去我的公号【猿圈奇妙屋】拿,直接回复【爱心】,即可拿到可直接运行的爱心动画文件(文件直接现成的哦!),心动不如行动。
回复后你点击链接再输入提取码,即可拿到一个[heart.zip]的压缩包,你们只需要下载到本地并解压即可,具体解压后得到的文件如下:
文件可直接通过浏览器打开即可实现播放。若要修改自定义文字,你可以通过选择打开方式【记事本】选中[DIY-heart.html]文件,然后找到第36行,具体请看如下截图:
将如下文字,修改成你想要的文字即可!比如如上我设置的就是"致我最爱的崽崽!"展示效果也就如下所示,字跟爱心跳动同频哦。
ok,教学我都基本说完了,如下贴出火爆全网同款的爱心源码,你们只需要将如下全代码复制粘贴保存到一个[xxx.txt]记事本中,然后将[.txt]格式改成[.html]后缀,最后通过浏览器打开即可播放。
